Use jQuery to load scripts asynchronously

jquery.loadasync.js

// Load scripts asynchronously
jQuery.loadAsync = function(url, callback) {
	// Don't use $.getScript since it disables caching
	jQuery.ajax({
		'url': url,
		'dataType': 'script',
		'cache': true,
		'success': callback || jQuery.noop
	});
};

Good tip. This is basically what $.getScript() does, but with the cache AJAX option, right? I was surprised to find that $.getScript() does not accept this option itself :/

Yeah, I’ve pinged @kswedberg about it — he’ll be adding it to the documentation page for $.getScript soon.

$.getScript support caching when using the options object signature like this:

$.getScript({
    url: "foo.js",
    cache: true
})
