In JavaScript, is there a way to get source code of a given URL?

Question

In JavaScript, is there a way to get source code of a page given its URL? Kind of equivalent to PHP\'s file_get_contents()

Answer 1

How about this: http://phpjs.org/functions/file_get_contents:400 ?

Answer 2

You can just download from a URL through XMLHttpRequest (or jQuery's ajax):

$.get(
    'yourfile.js', 
    function(data) { 
        // The source code is in data
    } 
);

Answer 3

I can do this with Pretty Diff tool api: http://prettydiff.com/api.php

The actual application, prettydiff.js, is JavaScript, and the service processing the requests on the server is also JavaScript. To see this in action go to the test link and use the "Source URI" method of input.
