Question

I have been using the fantastic jQuery library for quite some time and have become familar with its AJAX capabilities. I am working on a project which only requires the AJAX capabilities of jQuery. Separating this logic from jQuery is not so easy because there are so many dependencies.

I need an AJAX library which can achieve the following (in the same way that jQuery allows):

• Load script from another domain
• Load script from same domain
• Execute callback as soon as script has been executed

Using jQuery this can be achieved easily using:

$.ajax({
    type     : 'GET',
    url      : url,
    dataType : 'script',
    cache    : true,

    success: function() {
       // script has literally just finished executing...
    }
})

Which well established (and lightweight) open source library would achieve these requirements?

Okay, it turns out that the functionality that I require is not truly part of an AJAX response. Looking in the jQuery source I found that the “script” handler is essentially creating a “script” element temporarily and then removing it once it has loaded.
