问题:

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()

回答1:

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

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

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

回答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.
