Is it possible to hide the attributes of a HTML tag?
Suppose I have this code:
<div class="test"></div>
When someone use inspect elements on my website, they can only see this:
<div></div>
The reason why I want to do that is this:
I'm building a Web Application for my assigment at college, using Java as back-end language (I'm using Spring MVC Framework). I try to send a request and receive response without reload the entire page, and I found an example of using AJAX like this:
<button class="btn btn-success btn-lg" onclick="$.post('/waiter/order/2/menu?product=Crown%20Royale')">Crown Royale</button>
As you can see, the information of the request call is shown in HTML, and I want to hide it to keep the privacy of my Website.
No. Everything you send to the client, they will be able to see (and even change).
That's why serverside validation of forms is so important for example. Users can just turn off the required attribute and submit the form. If you don't have validation in place, your code will error.
You can't. The browser needs those tags and classes to show your webpage, and if your browser has them it won't make them private towards the end-user.
How do I create a link to a part of long webpage on another website that I don't control?
I thought you could use a variant of the #partofpage at the end of my link. Any suggestions?
Just append a # followed by the ID of the <a> tag (or other HTML tag, like a <section>) that you're trying to get to. For example, if you are trying to link to the header in this HTML:
<p>This is some content.</p>
<h2><a id="target">Some Header</a></h2>
<p>This is some more content.</p>
You could use the link Link.
Create a "jump link" using the following format:
http://www.example.com/somepage#anchor
Where anchor is the id of the element you wish to link to on that page. Use browser development tools / view source to find the id of the element you wish to link to.
If the element doesn't have an id and you don't control that site then you can't do it.
That is only possible if that site has declared anchors in the page.
It is done by giving a tag a name or id attribute, so look for any of those close to where you want to link to.
And then the syntax would be
text
In case the target page is on the same domain (i.e. shares the same origin with your page) and you don't mind creation of new tabs (1), you can (ab)use some JavaScript:
see tenth paragraph on another page
Trivia:
var w = window.open('some URL of the same origin');
w.onload = function(){
// do whatever you want with `this.document`, like
this.document.querySelecotor('footer').scrollIntoView()
}
Working example of such 'exploit' you can try right now could be:
javascript:(function(url,sel,w,el){w=window.open(url);w.addEventListener('load',function(){w.setTimeout(function(){el=w.document.querySelector(sel);el.scrollIntoView();el.style.backgroundColor='red'},1000)})})('https://stackoverflow.com/questions/45014240/link-to-a-specific-spot-on-a-page-i-cant-edit','footer')
If you enter this into location bar (mind that Chrome removes javascript: prefix when pasted from clipboard) or make it a href value of any link on this page (using Developer Tools) and click it, you will get another (duplicate) SO question page scrolled to the footer and footer painted red. (Delay added as a workaround for ajax-loaded content pushing footer down after load.)
Notes
Tested in current Chrome and Firefox, generally should work since it is based on defined standard behaviour.
Cannot be illustrated in interactive snippet here at SO, because they are isolated from the page origin-wise.
MDN: Window.open()
(1) window.open(url,'_self') seems to be breaking the load event; basically makes the window.open behave like a normal a href="" click navigation; haven't researched more yet.
The upcoming Chrome "Scroll to text" feature is exactly what you are looking for....
https://github.com/bokand/ScrollToTextFragment
You basically add #targetText= at the end of the URL and the browser will scroll to the target text and highlight it after the page is loaded.
It is in the version of Chrome that is running on my desk, but currently it must be manually enabled. Presumably it will soon be enabled by default in the production Chrome builds and other browsers will follow, so OK to start adding to your links now and it will start working then.
Edit: It's been implemented in Chrome. See https://chromestatus.com/feature/4733392803332096
You can NOW...
As of Chrome release 81 (Feb 2020), there is a new feature called Text Fragments. It allows you to provide a link that opens at the precise text specified (with that text highlighted).
At the moment, it works in Edge, Chrome and Opera but not in Firefox, Safari or Brave. (See note 6 at bottom for more)
For security reasons, the feature requires links to be opened in a noopener context. Therefore, make sure to include rel="noopener" in your anchor markup or add noopener to your Window.open() list of window functionality features.
You create the link to your desired text by appending this string to the end of the URL:
/#:~:text=
and providing the percent-encoded search string thus:
/#:~:text=String%20to%20focus%20on
Here is a working example:
https://newz.icu/#:~:text=Google%20surveillance%20increases
Notes:
Test the above link in Chrome or Opera only
In the above example, note that the text string is in a div that is normally hidden on page load - so in this example it is being displayed despite what would normally happen. Useful.
Recent versions of Chrome also include a new option when you Right-Click on selected text: Copy link to highlight. This will auto-create the direct-to-text link for you (i.e. it automatically appends the /#:~:text= to the text you highlighted) and place it in the clipboard - just paste it where desired.
Suppose you want to highlight an entire block of text? The Text Fragments feature allows specifying a starting%20phrase and an ending%20phrase (separated by a comma), and it will highlight all text in between:
https://newz.icu/#:~:text=Dr.%20Mullis,before%20now
Note the comma between Mullis and before

PS - Please forgive choice of example website. It simply had the desired
elements required for the demonstration. Hoping we can focus on function
rather than content.
First off target refers to the BlockID found in either HTML code or chromes developer tools that you are trying to link to. Each code is different and you will need to do some digging to find the ID you are trying to reference. It should look something like div class="page-container drawer-page-content" id"PageContainer"Note that this is the format for the whole referenced section, not an individual text or image. To do that you would need to find the same piece of code but relating to your target block. For example dv id="your-block-id" Anyways I was just reading over this thread and an idea came to my mind, if you are a Shopify user and want to do this it is pretty much the same thing as stated.
But instead of
> http://url.to.site.example/index.html#target
You would put
> http://example.com/target
For example, I am setting up a disclaimer page with links leading to a newsletter signup and shopping blocks on my home page so I insert https://mystore-classifier.com/#shopify-section-1528945200235 for my hyperlink.
Please note that the -classifier is for my internal use and doesn't apply to you. This is just so I can keep track of my stores.
If you want to link to something other than your homepage you would put
> http://mystore-classifier.example/pagename/#BlockID
I hope someone found this useful, if there is something wrong with my explanation please let me know as I am not an HTML programmer my language is C#!
It's now possible to create an "anchor" link that goes to a specific part of any webpage in most browsers in a few different ways.
All of them will create a link with an #anchor at the end, where "anchor" is the thing that you want to navigate to. The browser will interpret the part of the URL after the # to scroll to a specific part of the page.
Here are 3 ways to create a url like this:
Using an existing anchor. Perhaps there will be one in the URL as you scroll down the page. If not, look around the page for a header that has a little link icon to the left of it and click it to update the browsers navigation url.
Using any html element's id property or the name or id on an ("anchor") element. The other answers explain this quite well. You will have to open the developer console and inspect the part of the page to find an id (and you may not find one). It's a little different on each browser, but here's how to inspect an element in Chrome.
Using a text snippet to highlight part of the page.
Basically, html tag can have id="abc" as shown below:
<div id="abc">test</div>
<p id="abc">test</p>
<span id="abc">test</span>
<a id="abc">test</a>
And, "<a>" tag can also have name="abc" as shown below:
<a name="abc">test</a>
Then, you can use the id and name values "abc" with "#" in urls as shown below to go to the specific part of a page:
https://www.example.com/#abc
https://www.example.com/index.html#abc
Then, you can put the urls above in "<a>" tag to create the links to id="abc" and name="abc" as shown below:
test
test
And, if you want to go to the specific part of the same page, you can only put the id and name values "abc" with "#" in "<a>" tag to create the links to id="abc" and name="abc" as shown below:
<!-- Go to the specific part of the same page -->
test
<div id="abc">test</div>
<!-- Go to the specific part of the same page -->
test
<a name="abc">test</a>
I'm trying to learn the best way to create buttons via HTML/CSS.
I was using clickable div's before, but looks like this was not the best idea ever.
What about button's? Or a href's
Which way is the best to go with today (html5 css3)?
It depends on the behavior you are looking for. If its purpose is to link to another page then use an <a>. If it is for submitting a form or doing some sort of post or get I would use a button.
There is a web based project management product called Basecamp. When they first launched they were using <a> tags as delete buttons next to each individual task. Users who visited their internal pages while using the google web optimizer plugin for chrome were seeing all of their tasks marked as deleted. Google page optimizer looks for links in the page and triggers a click to pre-load future pages.
Let form follow function and you should be good to go :0)
One reason to favor buttons is that buttons are naturally better for accessibility, while using links, spans or other tags fails on that count. To get proper accessibility with those other elements, you have to use ARIA roles to fix them.
That's not a hack per se, since that's part of what ARIA roles are for. But it's an extra thing to learn about and make sure that you get right.
the best way to create buttons in html is to use
or
because when you buttons and inputs of type submit are used by default by the browser when you try to submit a form
for example :
<form action="somepage.php" method="POST">
<input type="text" name="name1">
<textarea></textarea>
<input type="submit" value="submit the form with a input of type submit">
</form>
only when the user click the submit button the form data are submited
BUT , when we use a or divs to play the role of buttons you need to call javascript and ask for help
FINNALY THE GOOD PRACTICE IS TO USE BUTTONS AND INPUT OF TYPE SUBMIT TO PLAY THE ROLE OF BUTTON EVERYTHING ELSE IS A CUSTOMIZATION THAT CAN INCREASE THE TIME TO LOAD THE PAGE
I simply want to add couple share button onto my page. And I see that people recommend different ways of doing it:
I see some articles using home?status:
<a href=”http://twitter.com/home?status=Currently reading <?php the_permalink(); ?>” title=”Click to send this page to Twitter!” target=”_blank” rel=”nofollow”>Share on Twitter</a>
and some using share?url:
Tweet
What's the difference?
Your first example simply updates the status with the text you enter. The second example has a lot more functionality.
share?url supports class attributes for the anchor tag. In the anchor tag you can add things like data-related to suggest accounts the user will follow after they share the content or if you don't supply a url it will look for the current url the call is being generated from and share that. It has a lot more functionality vs the dumbed down home?status call.

Short Version:
Do you know of any way to get an input button (submit) and an anchor tag to render the same visually using CSS and no Javascript?
Long Version:
I'm developing an ASP.NET MVC application. The site contains pages to view the details of or to create or update my models. The page actions are contained at the bottom of the form and typically include Update and Cancel or Edit, Delete and List (if on a details view page). The Update, Edit, and Delete actions post data from a form to the server, while the Cancel and List actions are/can be handled by appropriate GET requests. It's important to note that one of my design goals is to make the site work as identically as possible if Javascript is disabled to the way it does when Javascript is enabled. I also want the UI elements to render the same visually whether the element causes a postback or fires off a GET request.
In order to get the form submissions to work in the absence of Javascript, I think I must use submit buttons. I'm overriding, with CSS, the visually styling of the buttons to render much like the "buttons" on the top of the SO page -- flat, solid-color with plain text. I'd like the actions that generate GET requests to be handled with anchor tags, but I had problems getting these tags and the styled buttons to render identically. There seem to be issues with alignment and font-sizing. I was able to get them close but not identical.
EDIT: Styling differences using buttons and anchors included not being able to get the fonts to render in the same position relative to the baseline within the bounding box and getting the bounding box itself to render at the same size and alignment relative to the container. Things were just a few pixels off one way or the other regardless of my tweaks. If you've been able to get it to work, please let me know. Knowing that it's possible would make it easier to keep trying things until I could get it to work.
One thing I tried was wrapping the GET-actions around a button, styled like the form buttons. This worked great in Firefox, but not in IE7. Clicking on such a button in IE7 didn't propogate the click back to the anchor. What I've come up with now is to create a new form for the GET, using method="GET", associated with the required action. I wrap that around a submit button that has an onclick handler that sets location.href to the URL of the desired action. This renders visually the same and seems to work, even if the form is nested in another form. A minor niggle is that if Javascript is disabled, then my GET url contains a ? at the end instead of being the nice clean url that you would desire.
What I'd like to know is whether anyone else has solved this in a different way that would work better (and maybe require less HTML)? Do you have any other ideas that I could try? Any way to fix the ? on the GET url when the request is submitted as a post when Javascript is turned off?
Sample code below from a details view. I realize that I could (and arguably should) add the onclick handlers via javascript as well, but the code actuall reads better when I do it inline. I'm using HtmlHelper extensions to generate all of the mark up below. I have reformatted it to improve readability.
<form action="../Edit/2" class="inline-form" method="get">
<input class="button"
onclick="location.href='../Edit/2';return false;"
value="Edit"
type="submit" />
</form>
<form action="../Delete/2" class="inline-form" method="post">
<input class="button"
value="Delete"
type="submit" />
</form>
<form action="../List" class="inline-form" method="get">
<input class="button"
onclick="location.href='../List';return false;"
value="List Donors"
type="submit" />
</form>
