i am asking a very basic question. my problem is that i want to write url string like below
http://example.com/index.html/sometext
but when i write url like index.html/ it results in page not found. if url only upto index.html then it works. is there any way to write it in html pages. Please help Thanks
The URL you provided is not valid. The .html extension would be the end of the URL... with the format you've specified, it implies that another folder exists under index.html, which would never be possible. However, if you want to add parameters to the URL, you can add them like this:
http://example.com/index.html?text=sometext
You can then capture that data in your code.
EDIT
To answer the second question of how to pickup the URL parameters, you can use the method shown in this post:
http://www.jquerybyexample.net/2012/06/get-url-parameters-using-jquery.html
Basically, create a function as follows...
function GetURLParameter(sParam)
{
var sPageURL = window.location.search.substring(1);
var sURLVariables = sPageURL.split('&');
for (var i = 0; i < sURLVariables.length; i++)
{
var sParameterName = sURLVariables[i].split('=');
if (sParameterName[0] == sParam)
{
return sParameterName[1];
}
}
}
And you can use it like this:
var text = GetURLParameter('text');
You either want to use a QueryString like http://example.com/index.html&someVar=sometext
Or you will want to enable mod_rewrite to transform incoming urls to something that your backend technology understands.
There are lots of frameworks that enable you to use those fancy URLs like http://example.com/index/someText, for example Laravel for PHP or, ASP.NET MVC, or ...

I've just started using VueJS and I'm really liking it! :) I would like to save the values in the querystring to a VueJS variable - this is something super simple in handlebars + express, but seems more difficult in Vue.
Essentially I am looking for something similar to -
http://localhost:8080/?url=http%3A%2F%2Fwww.fake.co.uk&device=all
const app = new Vue({
...
data: {
url: req.body.url,
device: req.body.device
}
...
});
Google seemed to point me to vue-router, but I'm not sure if that's really what I need/how to use it. I'm currently using express to handle my backend logic/routes.
Thanks,
Ollie
You can either to put all your parameters in hash of the url, e.g.:
window.location.hash='your data here you will have to parse to'
and it will change your url - the part after #
Or if you insist to put them as query parameters (what's going after ?) using one of the solutions from Change URL parameters
You can use URLSearchParams and this polyfill to ensure that it will work on most web browsers.
// Assuming "?post=1234&action=edit"
var urlParams = new URLSearchParams(window.location.search);
console.log(urlParams.has('post')); // true
console.log(urlParams.get('action')); // "edit"
console.log(urlParams.getAll('action')); // ["edit"]
console.log(urlParams.toString()); // "?post=1234&action=edit"
console.log(urlParams.append('active', '1')); // "?post=1234&action=edit&active=1"

I need to download data feed from this website:
http://www.oddsportal.com/soccer/argentina/copa-argentina/rosario-central-racing-club-hnmq7gEQ/
In Chrome using developer tools I was able to find this link
http://fb.oddsportal.com/feed/match/1-1-hnmq7gEQ-1-2-yj45f.dat
which contains everything I need. Question is how to programmatically (preferably in java) get to the second link when I know the first.
Thanks in advance for any useful help.
This is quite similar to this issue. You can use that to get a String with all the sources. Then you just search the string to find what you're looking for. It can look like this.
First start ChromeDriver and navigate to the page you wish to scrap.
WebDriver driver = new ChromeDriver();
driver.get("http://www.oddsportal.com/soccer/argentina/copa-argentina/rosario-central-racing-club-hnmq7gEQ/");
Then download the sources into a string
String scriptToExecute = "var performance = window.performance || window.mozPerformance || window.msPerformance || window.webkitPerformance || {}; var network = performance.getEntries() || {}; return network;";
String netData = ((JavascriptExecutor) driver).executeScript(scriptToExecute).toString();
And finally search the string for the desired link
netData = netData.substring(netData.indexOf("fb.oddsportal"), netData.indexOf(".dat")+4);
System.out.println(netData);
You can use a framework such as JSoup in Java and scrape a page.
Document doc = Jsoup.connect("http://en.wikipedia.org/").get();
Once you have this you can then query the links on that page and save them to an array:
Elements links = doc.select("a[href]");
Then run though this array and follow them links.
for (Element link : links) {
Document doc = Jsoup.connect(link.attr("abs:href")).get();
}
I am building several apps and want to be able to reuse som code as separate HTML pages by passing parameters to them.
I would really like to pass parameters via ajax with one of these:
Alt1
$.mobile.pageContainer.pagecontainer("change", "../Photo/Photo.html", { reload: true, parameter: "dummyParameter"});
$.mobile.changePage("../Photo/Photo.html", { reloadPage: true, parameter: "dummyParameter"});
Problem is that the page wont reload.
If I use the below link the page is loaded/reloaded, but I cant seem to find the passed parameter.
Alt2
Or through a basic link
(I would prefeer to not generate the url in javascript as in alt2 but if what it takes...)
I use this code to try to retreive the parameters:
$(document).on("pagebeforechange", function (e, data) {
if (data.toPage[0].id == "Photo") {
//var parameters = $(this).data("url").split("?")[1];
//var parameter = parameters.replace("paremeter=", "");
var stuff = data.options.stuff;
//showStuff("#p2", stuff);
}
});
While I'm at it, if someone uses type script. Visual studio complains about that this call signature isnt correct:
$(document).on("pagebeforechange", function (e, data)
Expects one argument, the event, not the data. The plugin generates correct javascript but the IDE complains.
Thanks!
Our corporate wiki is Mediawiki. I have no problem to put iframe into my site to refer for some article on wiki.
But my own site have a lot of widgets and own style. I don't want to include Mediawiki navigation/search/login widgets, logo image.
Is it possible and how to get Mediawiki page contents without widgets (only article body)?
Yes, it is. You'll probably want to use the action=render url parameter, for example: http://en.wikipedia.org/w/index.php?action=render&title=Main_Page. Note that the stylesheets from the wiki aren't included, so you'll need to copy the relevant rules to your site's css files. See also this.
Thank waldir for answer!
After asking question I perform own research and end with code:
window.onload = function() {
httpRequest = new XMLHttpRequest();
httpRequest.onreadystatechange = function() {
if (httpRequest.readyState !== 4) {
console.log("Not ready, code: %o", httpRequest.readyState);
return;
}
if (httpRequest.status !== 200) {
console.log("Server error: %o", httpRequest.status);
return;
}
var json = JSON.parse(httpRequest.responseText);
console.log("json: %o", json);
var wiki = json.query.pages["1"].revisions[0]["*"];
console.log("wiki: %o", wiki);
var html = InstaView.convert(wiki);
console.log("html: %o", html);
document.getElementById('area').innerHTML = html;
};
var url = 'https://wiki.evil-company.com/api.php?action=query&prop=revisions&format=json&titles=Main_page&rvprop=timestamp|user|comment|content';
httpRequest.open('GET', url, true);
httpRequest.send(null);
}
Here I use https://github.com/cscott/instaview/blob/master/main.js project which is enhanced http://en.wikipedia.org/wiki/User:Pilaf to transform json output to HTML on browser side.
The reason for this code because our wiki is old or misconfigured and action=render is not available. But I trap into cross-domain scripting issue so I think that iframe with action=render is better solution.
See also How do you grab an article including the links in a usable format?
Another suggestion to use action=parse (http://en.wikipedia.org/w/api.php?action=parse&title=Linux) lead to warning:
You are looking at the HTML representation of the XML format.
HTML is good for debugging, but is unsuitable for application use.
Specify the format parameter to change the output format.
UPDATE
Perfect solution just append query action=render to any valid wiki URL like:
http://en.wikipedia.org/wiki/Linux?action=render
In a php file I can do:
<p><?php echo "hello!";?></p>
Is there a way to do this in node, if yes what's the logic for it?
I have an idea how could this be done:
Use an identifier markup for node in the HTML file like: <node>code</node>
Load & Parse HTML file in Node
Grab node markup from the HTML file and run it
But I'm not sure if this is the best way or even if it works :)
Please note I want to learn node.js, so express and other libraries and modules are not answers for me, because I want to know the logic of the process.
What your describing / asking for a node.js preprocessor. It does exist but it's considered harmful.
A better solution would be to use views used in express. Take a look at the screencasts.
If you must do everything from scratch then you can write a micro templating engine.
function render(_view, data) {
var view = render.views[view];
for (var key in data) {
var value = data[key];
view.replace("{{" + key + "}}", value);
}
return view;
}
render.views = {
"someView": "<p>{{foo}}</p>"
};
http.createServer(function(req, res) {
res.end(render("someView", {
"foo": "bar"
}));
});
There are good reasons why mixing php/asp/js code directly with HTML is bad. It does not promote seperation of concerns and leads to spaghetti code. The standard method these days is templating engines like the one above.
Want to learn more about micro templating? Read the article by J. Resig.
You can try using JooDee, a node webserver which allows you to embed serverside javascript in your web pages. If you are familiar with Node and PHP/ASP, it is a breeze to create pages. Here's a sample of what a page looks like below:
<!DOCTYPE html>
<html>
<: //server side code in here
var os = require('os');
var hostname = os.hostname();
:>
<body>
<div>Your hostname is <::hostname:></div>
</body>
</html>
Using JooDee also lets you expose server javascript vars to the client with no effort by attaching attributes to the 'Client' object server side, and accessing the generated 'Client' object in your client side javascript.

Use a template engine. From terminal
npm install ejs
In code:
var ejs = require('ejs');
var options = {
locals: {
foo: function() { return "bar"; }
}
};
var template = "<p><%= foo() %></p>";
console.log(ejs.render(template, options));
