Loading JavaScript Asynchronously

JQuery plugin:

(function($) {
    jQuery.asyncJs = function(js) {
        var s = document.createElement('script');
        s.type = 'text/javascript';
        s.async = true;
        s.src = js;
        document.getElementsByTagName('head')[0].appendChild(s);
    }
})(jQuery);

Use:

$.asyncJs('http://connect.facebook.net/ru_RU/all.js');
