jQuery.fetch. Makes loading remote data in elements a breeze. Only 250 bytes minified.

Example

HTML

<div class="remote" data-href="some-remote-url.html"> </div>

JavaScript

$().ready(function() { 
    $('.remote').fetch(function() { alert('data is loaded'); });
});

Note

The callback is stored with the element. Extra .fetch calls will execute the callback again unless you pass false or a new callback.
