Button to download HTML of a page - html

Is there a way to have a button/link and when you click on it, it will take the current page location and download an HTML version of it? It will be an iframe too, and the link should just download the iframe's content. Thanks!

The following JavaScript will take the current document and provide it as a download link. Tested in Chrome, not sure about others. Keep in mind that IE has limits for DataURI size. Furthermore, you'll lose your external images/CSS/etc, unless you inject the base tag into the top of the head tag (or find some other way to roll in resources):
// create the link to trigger download
// you could alternatively fetch an existing tag and update it
var a = document.createElement('a');
// send as type application/octet-stream to force download, not in browser
a.href =
"data:application/octet-stream;base64," +
btoa("<html>"+ document.getElementsByTagName('html')[0].outerHTML +
"</html>");
a.innerText = "Download this page";
// put the link wherever you want
document.body.appendChild(a);
EDIT: also doesn't provide a filename, or a .htm at the end of the download link... hmph. Those things can only really be provided by the Content-Disposition header, and that requires sending a request off to the server, so... not a fantastic user experience, but the easiest way to get the exact page state as the user sees it.

All you need is a simple script that takes the file name as a param and generates a zip. Here is an example in PHP.

How can I redirect the user from one page to another using jQuery or pure JavaScript?
One does not simply redirect using jQuery
jQuery is not necessary, and window.location.replace(...) will best simulate an HTTP redirect.
window.location.replace(...) is better than using window.location.href, because replace() does not keep the originating page in the session history, meaning the user won't get stuck in a never-ending back-button fiasco.
If you want to simulate someone clicking on a link, use
location.href
If you want to simulate an HTTP redirect, use location.replace
For example:
// similar behavior as an HTTP redirect
window.location.replace("http://stackoverflow.com");
// similar behavior as clicking on a link
window.location.href = "http://stackoverflow.com";
WARNING: This answer has merely been provided as a possible solution; it is obviously not the best solution, as it requires jQuery. Instead, prefer the pure JavaScript solution.
$(location).prop('href', 'http://stackoverflow.com')
Standard "vanilla" JavaScript way to redirect a page
window.location.href = 'newPage.html';
Or more simply: (since window is Global)
location.href = 'newPage.html';
If you are here because you are losing HTTP_REFERER when redirecting, keep reading:
(Otherwise ignore this last part)
The following section is for those using HTTP_REFERER as one of many security measures (although it isn't a great protective measure). If you're using Internet Explorer 8 or lower, these variables get lost when using any form of JavaScript page redirection (location.href, etc.).
Below we are going to implement an alternative for IE8 & lower so that we don't lose HTTP_REFERER. Otherwise, you can almost always simply use window.location.href.
Testing against HTTP_REFERER (URL pasting, session, etc.) can help tell whether a request is legitimate.
(Note: there are also ways to work-around / spoof these referrers, as noted by droop's link in the comments)
Simple cross-browser testing solution (fallback to window.location.href for Internet Explorer 9+ and all other browsers)
Usage: redirect('anotherpage.aspx');
function redirect (url) {
var ua = navigator.userAgent.toLowerCase(),
isIE = ua.indexOf('msie') !== -1,
version = parseInt(ua.substr(4, 2), 10);
// Internet Explorer 8 and lower
if (isIE && version < 9) {
var link = document.createElement('a');
link.href = url;
document.body.appendChild(link);
link.click();
}
// All other browsers can use the standard window.location.href (they don't lose HTTP_REFERER like Internet Explorer 8 & lower does)
else {
window.location.href = url;
}
}
There are lots of ways of doing this.
// window.location
window.location.replace('http://www.example.com')
window.location.assign('http://www.example.com')
window.location.href = 'http://www.example.com'
document.location.href = '/path'
// window.history
window.history.back()
window.history.go(-1)
// window.navigate; ONLY for old versions of Internet Explorer
window.navigate('top.jsp')
// Probably no bueno
self.location = 'http://www.example.com';
top.location = 'http://www.example.com';
// jQuery
$(location).attr('href','http://www.example.com')
$(window).attr('location','http://www.example.com')
$(location).prop('href', 'http://www.example.com')
This works for every browser:
window.location.href = 'your_url';
It would help if you were a little more descriptive in what you are trying to do. If you are trying to generate paged data, there are some options in how you do this. You can generate separate links for each page that you want to be able to get directly to.
<a href='/path-to-page?page=1' class='pager-link'>1</a>
<a href='/path-to-page?page=2' class='pager-link'>2</a>
<span class='pager-link current-page'>3</a>
...
Note that the current page in the example is handled differently in the code and with CSS.
If you want the paged data to be changed via AJAX, this is where jQuery would come in. What you would do is add a click handler to each of the anchor tags corresponding to a different page. This click handler would invoke some jQuery code that goes and fetches the next page via AJAX and updates the table with the new data. The example below assumes that you have a web service that returns the new page data.
$(document).ready( function() {
$('a.pager-link').click( function() {
var page = $(this).attr('href').split(/\?/)[1];
$.ajax({
type: 'POST',
url: '/path-to-service',
data: page,
success: function(content) {
$('#myTable').html(content); // replace
}
});
return false; // to stop link
});
});
I also think that location.replace(URL) is the best way, but if you want to notify the search engines about your redirection (they don't analyze JavaScript code to see the redirection) you should add the rel="canonical" meta tag to your website.
Adding a noscript section with a HTML refresh meta tag in it, is also a good solution. I suggest you to use this JavaScript redirection tool to create redirections. It also has Internet Explorer support to pass the HTTP referrer.
Sample code without delay looks like this:
<!-- Place this snippet right after opening the head tag to make it work properly -->
<!-- This code is licensed under GNU GPL v3 -->
<!-- You are allowed to freely copy, distribute and use this code, but removing author credit is strictly prohibited -->
<!-- Generated by http://insider.zone/tools/client-side-url-redirect-generator/ -->
<!-- REDIRECTING STARTS -->
<link rel="canonical" href="https://yourdomain.example/"/>
<noscript>
<meta http-equiv="refresh" content="0;URL=https://yourdomain.example/">
</noscript>
<!--[if lt IE 9]><script type="text/javascript">var IE_fix=true;</script><![endif]-->
<script type="text/javascript">
var url = "https://yourdomain.example/";
if(typeof IE_fix != "undefined") // IE8 and lower fix to pass the http referer
{
document.write("redirecting..."); // Don't remove this line or appendChild() will fail because it is called before document.onload to make the redirect as fast as possible. Nobody will see this text, it is only a tech fix.
var referLink = document.createElement("a");
referLink.href = url;
document.body.appendChild(referLink);
referLink.click();
}
else { window.location.replace(url); } // All other browsers
</script>
<!-- Credit goes to http://insider.zone/ -->
<!-- REDIRECTING ENDS -->
But if someone wants to redirect back to home page then he may use the following snippet.
window.location = window.location.host
It would be helpful if you have three different environments as development, staging, and production.
You can explore this window or window.location object by just putting these words in Chrome Console or Firebug's Console.
JavaScript provides you many methods to retrieve and change the current URL which is displayed in browser's address bar. All these methods uses the Location object, which is a property of the Window object. You can create a new Location object that has the current URL as follows..
var currentLocation = window.location;
Basic Structure of a URL
<protocol>//<hostname>:<port>/<pathname><search><hash>
Protocol -- Specifies the protocol name be used to access the resource on the Internet. (HTTP (without SSL) or HTTPS (with SSL))
hostname -- Host name specifies the host that owns the resource. For example, www.stackoverflow.com. A server provides services using the name of the host.
port -- A port number used to recognize a specific process to which an Internet or other network message is to be forwarded when it arrives at a server.
pathname -- The path gives info about the specific resource within the host that the Web client wants to access. For example, stackoverflow.com/index.html.
query -- A query string follows the path component, and provides a string of information that the resource can utilize for some purpose (for example, as parameters for a search or as data to be processed).
hash -- The anchor portion of a URL, includes the hash sign (#).
With these Location object properties you can access all of these URL components
hash -Sets or returns the anchor portion of a URL.
host -Sets
or returns the hostname and port of a URL.
hostname -Sets or
returns the hostname of a URL.
href -Sets or returns the entire
URL.
pathname -Sets or returns the path name of a URL.
port -Sets or returns the port number the server uses for a URL.
protocol -Sets or returns the protocol of a URL.
search -Sets
or returns the query portion of a URL
Now If you want to change a page or redirect the user to some other page you can use the href property of the Location object like this
You can use the href property of the Location object.
window.location.href = "http://www.stackoverflow.com";
Location Object also have these three methods
assign() -- Loads a new document.
reload() -- Reloads the current document.
replace() -- Replaces the current document with a new one
You can use assign() and replace methods also to redirect to other pages like these
location.assign("http://www.stackoverflow.com");
location.replace("http://www.stackoverflow.com");
How assign() and replace() differs -- The difference between replace() method and assign() method(), is that replace() removes the URL of the current document from the document history, means it is not possible to use the "back" button to navigate back to the original document. So Use the assign() method if you want to load a new document, andwant to give the option to navigate back to the original document.
You can change the location object href property using jQuery also like this
$(location).attr('href',url);
And hence you can redirect the user to some other url.
Basically jQuery is just a JavaScript framework and for doing some of the things like redirection in this case, you can just use pure JavaScript, so in that case you have 3 options using vanilla JavaScript:
1) Using location replace, this will replace the current history of the page, means that it is not possible to use the back button to go back to the original page.
window.location.replace("http://stackoverflow.com");
2) Using location assign, this will keep the history for you and with using back button, you can go back to the original page:
window.location.assign("http://stackoverflow.com");
3) I recommend using one of those previous ways, but this could be the third option using pure JavaScript:
window.location.href="http://stackoverflow.com";
You can also write a function in jQuery to handle it, but not recommended as it's only one line pure JavaScript function, also you can use all of above functions without window if you are already in the window scope, for example window.location.replace("http://stackoverflow.com"); could be location.replace("http://stackoverflow.com");
Also I show them all on the image below:
Should just be able to set using window.location.
Example:
window.location = "https://stackoverflow.com/";
Here is a past post on the subject: How do I redirect to another webpage?
Before I start, jQuery is a JavaScript library used for DOM manipulation. So you should not be using jQuery for a page redirect.
A quote from Jquery.com:
While jQuery might run without major issues in older browser versions,
we do not actively test jQuery in them and generally do not fix bugs
that may appear in them.
It was found here:
https://jquery.com/browser-support/
So jQuery is not an end-all and be-all solution for backwards compatibility.
The following solution using raw JavaScript works in all browsers and have been standard for a long time so you don't need any libraries for cross browser support.
This page will redirect to Google after 3000 milliseconds
<!DOCTYPE html>
<html>
<head>
<title>example</title>
</head>
<body>
<p>You will be redirected to google shortly.</p>
<script>
setTimeout(function(){
window.location.href="http://www.google.com"; // The URL that will be redirected too.
}, 3000); // The bigger the number the longer the delay.
</script>
</body>
</html>
Different options are as follows:
window.location.href="url"; // Simulates normal navigation to a new page
window.location.replace("url"); // Removes current URL from history and replaces it with a new URL
window.location.assign("url"); // Adds new URL to the history stack and redirects to the new URL
window.history.back(); // Simulates a back button click
window.history.go(-1); // Simulates a back button click
window.history.back(-1); // Simulates a back button click
window.navigate("page.html"); // Same as window.location="url"
When using replace, the back button will not go back to the redirect page, as if it was never in the history. If you want the user to be able to go back to the redirect page then use window.location.href or window.location.assign. If you do use an option that lets the user go back to the redirect page, remember that when you enter the redirect page it will redirect you back. So put that into consideration when picking an option for your redirect. Under conditions where the page is only redirecting when an action is done by the user then having the page in the back button history will be okay. But if the page auto redirects then you should use replace so that the user can use the back button without getting forced back to the page the redirect sends.
You can also use meta data to run a page redirect as followed.
META Refresh
<meta http-equiv="refresh" content="0;url=http://evil.example/" />
META Location
<meta http-equiv="location" content="URL=http://evil.example" />
BASE Hijacking
<base href="http://evil.example/" />
Many more methods to redirect your unsuspecting client to a page they may not wish to go can be found on this page (not one of them is reliant on jQuery):
https://code.google.com/p/html5security/wiki/RedirectionMethods
I would also like to point out, people don't like to be randomly redirected. Only redirect people when absolutely needed. If you start redirecting people randomly they will never go to your site again.
The next paragraph is hypothetical:
You also may get reported as a malicious site. If that happens then when people click on a link to your site the users browser may warn them that your site is malicious. What may also happen is search engines may start dropping your rating if people are reporting a bad experience on your site.
Please review Google Webmaster Guidelines about redirects:
https://support.google.com/webmasters/answer/2721217?hl=en&ref_topic=6001971
Here is a fun little page that kicks you out of the page.
<!DOCTYPE html>
<html>
<head>
<title>Go Away</title>
</head>
<body>
<h1>Go Away</h1>
<script>
setTimeout(function(){
window.history.back();
}, 3000);
</script>
</body>
</html>
If you combine the two page examples together you would have an infant loop of rerouting that will guarantee that your user will never want to use your site ever again.
var url = 'asdf.html';
window.location.href = url;
You can do that without jQuery as:
window.location = "http://yourdomain.com";
And if you want only jQuery then you can do it like:
$jq(window).attr("location","http://yourdomain.com");
This works with jQuery:
$(window).attr("location", "http://google.fr");
# HTML Page Redirect Using jQuery/JavaScript Method
Try this example code:
function YourJavaScriptFunction()
{
var i = $('#login').val();
if (i == 'login')
window.location = "Login.php";
else
window.location = "Logout.php";
}
If you want to give a complete URL as window.location = "www.google.co.in";.
Original question: "How to redirect using jQuery?", hence the answer implements jQuery >> Complimentary usage case.
To just redirect to a page with JavaScript:
window.location.href = "/contact/";
Or if you need a delay:
setTimeout(function () {
window.location.href = "/contact/";
}, 2000); // Time in milliseconds
jQuery allows you to select elements from a web page with ease. You can find anything you want on a page and then use jQuery to add special effects, react to user actions, or show and hide content inside or outside the element you have selected. All these tasks start with knowing how to select an element or an event.
$('a,img').on('click',function(e){
e.preventDefault();
$(this).animate({
opacity: 0 //Put some CSS animation here
}, 500);
setTimeout(function(){
// OK, finished jQuery staff, let's go redirect
window.location.href = "/contact/";
},500);
});
Imagine someone wrote a script/plugin with 10000 lines of code. With jQuery you can connect to this code with just a line or two.
So, the question is how to make a redirect page, and not how to redirect to a website?
You only need to use JavaScript for this. Here is some tiny code that will create a dynamic redirect page.
<script>
var url = window.location.search.split('url=')[1]; // Get the URL after ?url=
if( url ) window.location.replace(url);
</script>
So say you just put this snippet into a redirect/index.html file on your website you can use it like so.
http://www.mywebsite.com/redirect?url=http://stackoverflow.com
And if you go to that link it will automatically redirect you to stackoverflow.com.
Link to Documentation
And that's how you make a Simple redirect page with JavaScript
Edit:
There is also one thing to note. I have added window.location.replace in my code because I think it suits a redirect page, but, you must know that when using window.location.replace and you get redirected, when you press the back button in your browser it will not got back to the redirect page, and it will go back to the page before it, take a look at this little demo thing.
Example:
The process: store home => redirect page to google => google
When at google: google => back button in browser => store home
So, if this suits your needs then everything should be fine. If you want to include the redirect page in the browser history replace this
if( url ) window.location.replace(url);
with
if( url ) window.location.href = url;
You need to put this line in your code:
$(location).attr("href","http://stackoverflow.com");
If you don't have jQuery, go with JavaScript:
window.location.replace("http://stackoverflow.com");
window.location.href("http://stackoverflow.com");
On your click function, just add:
window.location.href = "The URL where you want to redirect";
$('#id').click(function(){
window.location.href = "http://www.google.com";
});
Try this:
location.assign("http://www.google.com");
Code snippet of example.
jQuery is not needed. You can do this:
window.open("URL","_self","","")
It is that easy!
The best way to initiate an HTTP request is with document.loacation.href.replace('URL').
Using JavaScript:
Method 1:
window.location.href="http://google.com";
Method 2:
window.location.replace("http://google.com");
Using jQuery:
Method 1: $(location)
$(location).attr('href', 'http://google.com');
Method 2: Reusable Function
jQuery.fn.redirectTo = function(url){
window.location.href = url;
}
jQuery(window).redirectTo("http://google.com");
First write properly. You want to navigate within an application for another link from your application for another link. Here is the code:
window.location.href = "http://www.google.com";
And if you want to navigate pages within your application then I also have code, if you want.
You can redirect in jQuery like this:
$(location).attr('href', 'http://yourPage.com/');
JavaScript is very extensive. If you want to jump to another page you have three options.
window.location.href='otherpage.com';
window.location.assign('otherpage.com');
//and...
window.location.replace('otherpage.com');
As you want to move to another page, you can use any from these if this is your requirement.
However all three options are limited to different situations. Chose wisely according to your requirement.
If you are interested in more knowledge about the concept, you can go through further.
window.location.href; // Returns the href (URL) of the current page
window.location.hostname; // Returns the domain name of the web host
window.location.pathname; // Returns the path and filename of the current page
window.location.protocol; // Returns the web protocol used (http: or https:)
window.location.assign; // Loads a new document
window.location.replace; // RReplace the current location with new one.
In JavaScript and jQuery we can use the following code to redirect the one page to another page:
window.location.href="http://google.com";
window.location.replace("page1.html");
ECMAScript 6 + jQuery, 85 bytes
$({jQueryCode:(url)=>location.replace(url)}).attr("jQueryCode")("http://example.com")
Please don't kill me, this is a joke. It's a joke. This is a joke.
This did "provide an answer to the question", in the sense that it asked for a solution "using jQuery" which in this case entails forcing it into the equation somehow.
Ferrybig apparently needs the joke explained (still joking, I'm sure there are limited options on the review form), so without further ado:
Other answers are using jQuery's attr() on the location or window objects unnecessarily.
This answer also abuses it, but in a more ridiculous way. Instead of using it to set the location, this uses attr() to retrieve a function that sets the location.
The function is named jQueryCode even though there's nothing jQuery about it, and calling a function somethingCode is just horrible, especially when the something is not even a language.
The "85 bytes" is a reference to Code Golf. Golfing is obviously not something you should do outside of code golf, and furthermore this answer is clearly not actually golfed.
Basically, cringe.
Javascript:
window.location.href='www.your_url.com';
window.top.location.href='www.your_url.com';
window.location.replace('www.your_url.com');
Jquery:
var url='www.your_url.com';
$(location).attr('href',url);
$(location).prop('href',url);//instead of location you can use window
Here is a time-delay redirection. You can set the delay time to whatever you want:
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Your Document Title</title>
<script type="text/javascript">
function delayer(delay) {
onLoad = setTimeout('window.location.href = "http://www.google.com/"', delay);
}
</script>
</head>
<body>
<script>
delayer(8000)
</script>
<div>You will be redirected in 8 seconds!</div>
</body>
</html>

But if someone wants to redirect back to home page then he may use the following snippet.
window.location = window.location.host
It would be helpful if you have three different environments as development, staging, and production.
You can explore this window or window.location object by just putting these words in Chrome Console or Firebug's Console.
JavaScript provides you many methods to retrieve and change the current URL which is displayed in browser's address bar. All these methods uses the Location object, which is a property of the Window object. You can create a new Location object that has the current URL as follows..
var currentLocation = window.location;
Basic Structure of a URL
<protocol>//<hostname>:<port>/<pathname><search><hash>
Protocol -- Specifies the protocol name be used to access the resource on the Internet. (HTTP (without SSL) or HTTPS (with SSL))
hostname -- Host name specifies the host that owns the resource. For example, www.stackoverflow.com. A server provides services using the name of the host.
port -- A port number used to recognize a specific process to which an Internet or other network message is to be forwarded when it arrives at a server.
pathname -- The path gives info about the specific resource within the host that the Web client wants to access. For example, stackoverflow.com/index.html.
query -- A query string follows the path component, and provides a string of information that the resource can utilize for some purpose (for example, as parameters for a search or as data to be processed).
hash -- The anchor portion of a URL, includes the hash sign (#).
With these Location object properties you can access all of these URL components
hash -Sets or returns the anchor portion of a URL.
host -Sets
or returns the hostname and port of a URL.
hostname -Sets or
returns the hostname of a URL.
href -Sets or returns the entire
URL.
pathname -Sets or returns the path name of a URL.
port -Sets or returns the port number the server uses for a URL.
protocol -Sets or returns the protocol of a URL.
search -Sets
or returns the query portion of a URL
Now If you want to change a page or redirect the user to some other page you can use the href property of the Location object like this
You can use the href property of the Location object.
window.location.href = "http://www.stackoverflow.com";
Location Object also have these three methods
assign() -- Loads a new document.
reload() -- Reloads the current document.
replace() -- Replaces the current document with a new one
You can use assign() and replace methods also to redirect to other pages like these
location.assign("http://www.stackoverflow.com");
location.replace("http://www.stackoverflow.com");
How assign() and replace() differs -- The difference between replace() method and assign() method(), is that replace() removes the URL of the current document from the document history, means it is not possible to use the "back" button to navigate back to the original document. So Use the assign() method if you want to load a new document, andwant to give the option to navigate back to the original document.
You can change the location object href property using jQuery also like this
$(location).attr('href',url);
And hence you can redirect the user to some other url.
Basically jQuery is just a JavaScript framework and for doing some of the things like redirection in this case, you can just use pure JavaScript, so in that case you have 3 options using vanilla JavaScript:
1) Using location replace, this will replace the current history of the page, means that it is not possible to use the back button to go back to the original page.
window.location.replace("http://stackoverflow.com");
2) Using location assign, this will keep the history for you and with using back button, you can go back to the original page:
window.location.assign("http://stackoverflow.com");
3) I recommend using one of those previous ways, but this could be the third option using pure JavaScript:
window.location.href="http://stackoverflow.com";
You can also write a function in jQuery to handle it, but not recommended as it's only one line pure JavaScript function, also you can use all of above functions without window if you are already in the window scope, for example window.location.replace("http://stackoverflow.com"); could be location.replace("http://stackoverflow.com");
Also I show them all on the image below:
Should just be able to set using window.location.
Example:
window.location = "https://stackoverflow.com/";
Here is a past post on the subject: How do I redirect to another webpage?
Before I start, jQuery is a JavaScript library used for DOM manipulation. So you should not be using jQuery for a page redirect.
A quote from Jquery.com:
While jQuery might run without major issues in older browser versions,
we do not actively test jQuery in them and generally do not fix bugs
that may appear in them.
It was found here:
https://jquery.com/browser-support/
So jQuery is not an end-all and be-all solution for backwards compatibility.
The following solution using raw JavaScript works in all browsers and have been standard for a long time so you don't need any libraries for cross browser support.
This page will redirect to Google after 3000 milliseconds
<!DOCTYPE html>
<html>
<head>
<title>example</title>
</head>
<body>
<p>You will be redirected to google shortly.</p>
<script>
setTimeout(function(){
window.location.href="http://www.google.com"; // The URL that will be redirected too.
}, 3000); // The bigger the number the longer the delay.
</script>
</body>
</html>
Different options are as follows:
window.location.href="url"; // Simulates normal navigation to a new page
window.location.replace("url"); // Removes current URL from history and replaces it with a new URL
window.location.assign("url"); // Adds new URL to the history stack and redirects to the new URL
window.history.back(); // Simulates a back button click
window.history.go(-1); // Simulates a back button click
window.history.back(-1); // Simulates a back button click
window.navigate("page.html"); // Same as window.location="url"
When using replace, the back button will not go back to the redirect page, as if it was never in the history. If you want the user to be able to go back to the redirect page then use window.location.href or window.location.assign. If you do use an option that lets the user go back to the redirect page, remember that when you enter the redirect page it will redirect you back. So put that into consideration when picking an option for your redirect. Under conditions where the page is only redirecting when an action is done by the user then having the page in the back button history will be okay. But if the page auto redirects then you should use replace so that the user can use the back button without getting forced back to the page the redirect sends.
You can also use meta data to run a page redirect as followed.
META Refresh
<meta http-equiv="refresh" content="0;url=http://evil.example/" />
META Location
<meta http-equiv="location" content="URL=http://evil.example" />
BASE Hijacking
<base href="http://evil.example/" />
Many more methods to redirect your unsuspecting client to a page they may not wish to go can be found on this page (not one of them is reliant on jQuery):
https://code.google.com/p/html5security/wiki/RedirectionMethods
I would also like to point out, people don't like to be randomly redirected. Only redirect people when absolutely needed. If you start redirecting people randomly they will never go to your site again.
The next paragraph is hypothetical:
You also may get reported as a malicious site. If that happens then when people click on a link to your site the users browser may warn them that your site is malicious. What may also happen is search engines may start dropping your rating if people are reporting a bad experience on your site.
Please review Google Webmaster Guidelines about redirects:
https://support.google.com/webmasters/answer/2721217?hl=en&ref_topic=6001971
Here is a fun little page that kicks you out of the page.
<!DOCTYPE html>
<html>
<head>
<title>Go Away</title>
</head>
<body>
<h1>Go Away</h1>
<script>
setTimeout(function(){
window.history.back();
}, 3000);
</script>
</body>
</html>
If you combine the two page examples together you would have an infant loop of rerouting that will guarantee that your user will never want to use your site ever again.
var url = 'asdf.html';
window.location.href = url;
You can do that without jQuery as:
window.location = "http://yourdomain.com";
And if you want only jQuery then you can do it like:
$jq(window).attr("location","http://yourdomain.com");
This works with jQuery:
$(window).attr("location", "http://google.fr");
# HTML Page Redirect Using jQuery/JavaScript Method
Try this example code:
function YourJavaScriptFunction()
{
var i = $('#login').val();
if (i == 'login')
window.location = "Login.php";
else
window.location = "Logout.php";
}
If you want to give a complete URL as window.location = "www.google.co.in";.
Original question: "How to redirect using jQuery?", hence the answer implements jQuery >> Complimentary usage case.
To just redirect to a page with JavaScript:
window.location.href = "/contact/";
Or if you need a delay:
setTimeout(function () {
window.location.href = "/contact/";
}, 2000); // Time in milliseconds
jQuery allows you to select elements from a web page with ease. You can find anything you want on a page and then use jQuery to add special effects, react to user actions, or show and hide content inside or outside the element you have selected. All these tasks start with knowing how to select an element or an event.
$('a,img').on('click',function(e){
e.preventDefault();
$(this).animate({
opacity: 0 //Put some CSS animation here
}, 500);
setTimeout(function(){
// OK, finished jQuery staff, let's go redirect
window.location.href = "/contact/";
},500);
});
Imagine someone wrote a script/plugin with 10000 lines of code. With jQuery you can connect to this code with just a line or two.
So, the question is how to make a redirect page, and not how to redirect to a website?
You only need to use JavaScript for this. Here is some tiny code that will create a dynamic redirect page.
<script>
var url = window.location.search.split('url=')[1]; // Get the URL after ?url=
if( url ) window.location.replace(url);
</script>
So say you just put this snippet into a redirect/index.html file on your website you can use it like so.
http://www.mywebsite.com/redirect?url=http://stackoverflow.com
And if you go to that link it will automatically redirect you to stackoverflow.com.
Link to Documentation
And that's how you make a Simple redirect page with JavaScript
Edit:
There is also one thing to note. I have added window.location.replace in my code because I think it suits a redirect page, but, you must know that when using window.location.replace and you get redirected, when you press the back button in your browser it will not got back to the redirect page, and it will go back to the page before it, take a look at this little demo thing.
Example:
The process: store home => redirect page to google => google
When at google: google => back button in browser => store home
So, if this suits your needs then everything should be fine. If you want to include the redirect page in the browser history replace this
if( url ) window.location.replace(url);
with
if( url ) window.location.href = url;
You need to put this line in your code:
$(location).attr("href","http://stackoverflow.com");
If you don't have jQuery, go with JavaScript:
window.location.replace("http://stackoverflow.com");
window.location.href("http://stackoverflow.com");
On your click function, just add:
window.location.href = "The URL where you want to redirect";
$('#id').click(function(){
window.location.href = "http://www.google.com";
});
Try this:
location.assign("http://www.google.com");
Code snippet of example.
jQuery is not needed. You can do this:
window.open("URL","_self","","")
It is that easy!
The best way to initiate an HTTP request is with document.loacation.href.replace('URL').
Using JavaScript:
Method 1:
window.location.href="http://google.com";
Method 2:
window.location.replace("http://google.com");
Using jQuery:
Method 1: $(location)
$(location).attr('href', 'http://google.com');
Method 2: Reusable Function
jQuery.fn.redirectTo = function(url){
window.location.href = url;
}
jQuery(window).redirectTo("http://google.com");
First write properly. You want to navigate within an application for another link from your application for another link. Here is the code:
window.location.href = "http://www.google.com";
And if you want to navigate pages within your application then I also have code, if you want.
You can redirect in jQuery like this:
$(location).attr('href', 'http://yourPage.com/');
JavaScript is very extensive. If you want to jump to another page you have three options.
window.location.href='otherpage.com';
window.location.assign('otherpage.com');
//and...
window.location.replace('otherpage.com');
As you want to move to another page, you can use any from these if this is your requirement.
However all three options are limited to different situations. Chose wisely according to your requirement.
If you are interested in more knowledge about the concept, you can go through further.
window.location.href; // Returns the href (URL) of the current page
window.location.hostname; // Returns the domain name of the web host
window.location.pathname; // Returns the path and filename of the current page
window.location.protocol; // Returns the web protocol used (http: or https:)
window.location.assign; // Loads a new document
window.location.replace; // RReplace the current location with new one.
In JavaScript and jQuery we can use the following code to redirect the one page to another page:
window.location.href="http://google.com";
window.location.replace("page1.html");
ECMAScript 6 + jQuery, 85 bytes
$({jQueryCode:(url)=>location.replace(url)}).attr("jQueryCode")("http://example.com")
Please don't kill me, this is a joke. It's a joke. This is a joke.
This did "provide an answer to the question", in the sense that it asked for a solution "using jQuery" which in this case entails forcing it into the equation somehow.
Ferrybig apparently needs the joke explained (still joking, I'm sure there are limited options on the review form), so without further ado:
Other answers are using jQuery's attr() on the location or window objects unnecessarily.
This answer also abuses it, but in a more ridiculous way. Instead of using it to set the location, this uses attr() to retrieve a function that sets the location.
The function is named jQueryCode even though there's nothing jQuery about it, and calling a function somethingCode is just horrible, especially when the something is not even a language.
The "85 bytes" is a reference to Code Golf. Golfing is obviously not something you should do outside of code golf, and furthermore this answer is clearly not actually golfed.
Basically, cringe.
Javascript:
window.location.href='www.your_url.com';
window.top.location.href='www.your_url.com';
window.location.replace('www.your_url.com');
Jquery:
var url='www.your_url.com';
$(location).attr('href',url);
$(location).prop('href',url);//instead of location you can use window
Here is a time-delay redirection. You can set the delay time to whatever you want:
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Your Document Title</title>
<script type="text/javascript">
function delayer(delay) {
onLoad = setTimeout('window.location.href = "http://www.google.com/"', delay);
}
</script>
</head>
<body>
<script>
delayer(8000)
</script>
<div>You will be redirected in 8 seconds!</div>
</body>
</html>

How to embed path to the current path at anchor href?

For example, right now I'm at http://example.com/practice
If I have a link within the generated page: Click here, I'm directed to http://example.com/5.
Now I know that this is the usual method of relative path. But what I actually need here is so that the link will take me to http://example.com/practice/5 without I need to specify practice or example.com on that page. Preferred if not using any Javascript if possible, but if it is not possible, then I guess I'll have to use Javascript then.
I've already tried Click here and Click here and they still work exactly like "5".
Please help. Thanks.
You can do something in your javascript where you grab the current location with window.location.href (there may be a better way depending if you're using any js frameworks). For example for this page, window.location.href returns https://stackoverflow.com/questions/38284340/how-to-embed-path-to-the-current-path-at-anchor-href
You could then do something like this
var baseUrl = window.location.href;
var aTag = document.querySelector(<selector for your anchor tag>);
aTag.setAttribute("href", baseUrl + "/" + <url we want to go to>);
So essentially we grab our current location, change the href of the tag we want to navigate to, then add whatever subroute we want to go to at the end. Kind of a weird way to do it, but like I said earlier, there may be an easier way if you're using react or angular or some other framework or library.

What does "blob" mean in the `href` property in "<link>"? [duplicate]

My page generates a URL like this: "blob:http%3A//localhost%3A8383/568233a1-8b13-48b3-84d5-cca045ae384f" How can I convert it to a normal address?
I'm using it as an <img>'s src attribute.
A URL that was created from a JavaScript Blob can not be converted to a "normal" URL.
A blob: URL does not refer to data the exists on the server, it refers to data that your browser currently has in memory, for the current page. It will not be available on other pages, it will not be available in other browsers, and it will not be available from other computers.
Therefore it does not make sense, in general, to convert a Blob URL to a "normal" URL. If you wanted an ordinary URL, you would have to send the data from the browser to a server and have the server make it available like an ordinary file.
It is possible convert a blob: URL into a data: URL, at least in Chrome. You can use an AJAX request to "fetch" the data from the blob: URL (even though it's really just pulling it out of your browser's memory, not making an HTTP request).
Here's an example:
var blob = new Blob(["Hello, world!"], { type: 'text/plain' });
var blobUrl = URL.createObjectURL(blob);
var xhr = new XMLHttpRequest;
xhr.responseType = 'blob';
xhr.onload = function() {
var recoveredBlob = xhr.response;
var reader = new FileReader;
reader.onload = function() {
var blobAsDataUrl = reader.result;
window.location = blobAsDataUrl;
};
reader.readAsDataURL(recoveredBlob);
};
xhr.open('GET', blobUrl);
xhr.send();
data: URLs are probably not what you mean by "normal" and can be problematically large. However they do work like normal URLs in that they can be shared; they're not specific to the current browser or session.
another way to create a data url from blob url may be using canvas.
var canvas = document.createElement("canvas")
var context = canvas.getContext("2d")
context.drawImage(img, 0, 0) // i assume that img.src is your blob url
var dataurl = canvas.toDataURL("your prefer type", your prefer quality)
as what i saw in mdn, canvas.toDataURL is supported well by browsers. (except ie<9, always ie<9)
For those who came here looking for a way to download a blob url video / audio, this answer worked for me. In short, you would need to find an *.m3u8 file on the desired web page through Chrome -> Network tab and paste it into a VLC player.
Another guide shows you how to save a stream with the VLC Player.
UPDATE:
An alternative way of downloading the videos from a blob url is by using the mass downloader and joining the files together.
Download Videos Part
Open network tab in chrome dev tools
Reload the webpage
Filter .m3u8 files
Look through all filtered files and find the playlist of the '.ts' files. It should look something like this:
You need to extract those links somehow. Either download and edit the file manually OR use any other method you like. As you can see, those links are very similar, the only thing that differs is the serial number of the video: 's-0-v1-a1.ts', 's-1-v1-a1.ts' etc.
https://some-website.net/del/8cf.m3u8/s-0-v1-a1.ts
https://some-website.net/del/8cf.m3u8/s-1-v1-a1.ts
https://some-website.net/del/8cf.m3u8/s-2-v1-a1.ts
and so on up to the last link in the .m3u8 playlist file. These .ts files are actually your video. You need to download all of them.
For bulk downloading I prefer using the Simple Mass Downloader extension for Chrome (https://chrome.google.com/webstore/detail/simple-mass-downloader/abdkkegmcbiomijcbdaodaflgehfffed)
If you opt in for the Simple Mass Downloader, you need to:
a. Select a Pattern URL
b. Enter your link in the address field with only one modification: that part of the link that is changing for each next video needs to be replaced with the pattern in square brackets [0:400] where 0 is the first file name and 400 is the last one. So your link should look something like this https://some-website.net/del/8cf.m3u8/s-[0:400]-v1-a1.ts.
Afterwards hit the Import button to add these links into the Download List of Mass Downloader.
c. The next action may ask you for the destination folder for EACH video you download. So it is highly recommended to specify the default download folder in Chrome Settings and disable the Select Destination option in Chrome Settings as well. This will save you a lot of time! Additionally you may want you specify the folder where these files will go to:
c1. Click on Select All checkbox to select all files from the Download List.
c2. Click on the Download button in the bottom right corner of the SMD extension window. It will take you to next tab to start downloading
c3. Hit Start selected. This will download all vids automatically into the download folder.
That is it! Simply wait till all files are downloaded and you can watch them via the VLC Player or any other player that supports the .ts format. However, if you want to have one video instead of those you have downloaded, you need to join all these mini-videos together
Joining Videos Part
Since I am working on Mac, I am not aware of how you would do this on Windows. If you are the Windows user and you want to merge the videos, feel free to google for the windows solution. The next steps are applicable for Mac only.
Open Terminal in the folder you want the new video to be saved in
Type: cat and hit space
Open the folder where you downloaded your .ts video. Select all .ts videos that you want to join (use your mouse or cmd+A)
Drag and drop them into the terminal
Hit space
Hit >
Hit Space
Type the name of the new video, e.g. my_new_video.ts. Please note that the format has to be the same as in the original videos, otherwise it will take long time to convert and even may fail!
Hit Enter. Wait for the terminal to finish the joining process and enjoy watching your video!
Found this answer here and wanted to reference it as it appear much cleaner than the accepted answer:
function blobToDataURL(blob, callback) {
var fileReader = new FileReader();
fileReader.onload = function(e) {callback(e.target.result);}
fileReader.readAsDataURL(blob);
}
I'm very late to the party.
If you want to download the content you can simply use fetch now
fetch(blobURL)
.then(res => res.blob())
.then(blob => /*do what you want with the blob here*/)
Here the solution:
let blob = new Blob(chunks, { 'type' : 'video/mp4;' });
let videoURL = window.URL.createObjectURL(blob);
const blobF = await fetch(videoURL).then(res => res.blob())
As the previous answer have said, there is no way to decode it back to url, even when you try to see it from the chrome devtools panel, the url may be still encoded as blob.
However, it's possible to get the data, another way to obtain the data is to put it into an anchor and directly download it.
<a href="blob:http://example.com/xxxx-xxxx-xxxx-xxxx" download>download</a>
Insert this to the page containing blob url and click the button, you get the content.
Another way is to intercept the ajax call via a proxy server, then you could view the true image url.

How can I create download link in HTML?

I have a basic idea of HTML. I want to create the download link in my sample website, but I don't have idea of how to create it. How do I make a link to download a file rather than visit it?
In modern browsers that support HTML5, the following is possible:
<a href="link/to/your/download/file" download>Download link</a>
You also can use this:
Download link
This will allow you to change the name of the file actually being downloaded.
This answer is outdated. We now have the download attribute. (see also this link to MDN)
If by "the download link" you mean a link to a file to download, use
Download
the target=_blank will make a new browser window appear before the download starts. That window will usually be closed when the browser discovers that the resource is a file download.
Note that file types known to the browser (e.g. JPG or GIF images) will usually be opened within the browser.
You can try sending the right headers to force a download like outlined e.g. here. (server side scripting or access to the server settings is required for that.)
In addition (or in replacement) to the HTML5's <a download attribute already mentioned,
the browser's download to disk behavior can also be triggered by the following http response header:
Content-Disposition: attachment; filename=ProposedFileName.txt;
This was the way to do before HTML5 (and still works with browsers supporting HTML5).
A download link would be a link to the resource you want to download. It is constructed in the same way that any other link would be:
Link
Link to installer
To link to the file, do the same as any other page link:
link text
To force things to download even if they have an embedded plugin (Windows + QuickTime = ugh), you can use this in your htaccess / apache2.conf:
AddType application/octet-stream EXTENSION
This thread is probably ancient by now, but this works in html5 for my local file.
For pdfs:
<p>test pdf</p>
This should open the pdf in a new windows and allow you to download it (in firefox at least). For any other file, just make it the filename. For images and music, you'd want to store them in the same directory as your site though. So it'd be like
<p><a href="images/logo2.png" download>test pdf</a></p>
There's one more subtlety that can help here.
I want to have links that both allow in-browser playing and display as well as one for purely downloading. The new download attribute is fine, but doesn't work all the time because the browser's compulsion to play the or display the file is still very strong.
BUT.. this is based on examining the extension on the URL's filename!You don't want to fiddle with the server's extension mapping because you want to deliver the same file two different ways. So for the download, you can fool it by softlinking the file to a name that is opaque to this extension mapping, pointing to it, and then using download's rename feature to fix the name.
<a target="_blank" download="realname.mp3" href="realname.UNKNOWN">Download it</a>
<a target="_blank" href="realname.mp3">Play it</a>
I was hoping just throwing a dummy query on the end or otherwise obfuscating the extension would work, but sadly, it doesn't.
You can use in two ways
<a href="yourfilename" download>Download</a>
it will download file with original name In Old Browsers this option was not available
2nd
Download
Here You have option to rename your file and download with a different name
The download attribute is new for the <a> tag in HTML5
<a href="http://www.odin.com/form.pdf" download>Download Form</a>
or
Download Form
I prefer the first one it is preferable in respect to any extension.
If you host your file in AWS, this may work for you. The code is very easy to understand. Because the browser doesn't support same-origin download links, 1 way to solve it is to convert the image URL to a base64 URL. Then, you can download it normally.
var canvas = document.createElement("canvas")
var ctx = canvas.getContext('2d')
var img = new Image()
img.src = your_file_url + '?' + new Date().getTime();
img.setAttribute('crossOrigin', '')
var array = your_file_url.src.split("/")
var fileName = array[array.length - 1]
img.onload = function() {
canvas.width = img.naturalWidth
canvas.height = img.naturalHeight
ctx.drawImage(img,
0, 0, img.naturalWidth, img.naturalHeight,
0, 0, canvas.width, canvas.height)
var dataUrl = canvas.toDataURL("image/png", 1)
var a = document.createElement('a')
a.href = dataUrl
a.download = fileName
document.body.appendChild(a)
a.click()
document.body.removeChild(a)
}
Like this
Link name
So a file name.jpg on a site example.com would look like this
Image
i know i am late but this is what i got after 1 hour of search
<?php
$file = 'file.pdf';
if (! file) {
die('file not found'); //Or do something
} else {
if(isset($_GET['file'])){
// Set headers
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-Disposition: attachment; filename=$file");
header("Content-Type: application/zip");
header("Content-Transfer-Encoding: binary");
// Read the file from disk
readfile($file); }
}
?>
and for downloadable link i did this
Download PDF
