$.getScript mutiple scripts

This is very useful for loading mutiple scripts with a callback function containing code that you want to run only when all of the scripts have been loaded. To load mutiple scripts you need to enhance the AJAX $.getScript() function to handle mutiple scripts then simply add them to an array for the first parameter and the callback function as the second parameter.

Single jQuery Get Script

$.getScript('script1.js', function(data, textStatus) {
    //do something after script has loaded
});

Multiple jQuery Get Scripts

/* enhance $.getSctipt to handle mutiple scripts */
var getScript = jQuery.getScript;
jQuery.getScript = function( resources, callback ) {
    var // reference declaration & localization
    length = resources.length,
    handler = function() { counter++; },
    deferreds = [],
    counter = 0,
    idx = 0;
    for ( ; idx < length; idx++ ) {
        deferreds.push(
            getScript( resources[ idx ], handler )
        );
    }
    jQuery.when.apply( null, deferreds ).then(function() {
        callback && callback();
    });
};
$.getScript(['script1.js','script2.js','script3.js'], function() {
    //do something after all scripts have loaded
});
//or seperate into an array to include
var scripts = ['script1.js','script2.js','script3.js'];
$.getScript(scripts, function(data, textStatus) {
    //do something after all scripts have loaded
});

Any way I discovered:

You could just do it this way, say you had to load 3 scripts and the third has a callback.

$.get("js/ext/flowplayer-3.2.8.min.js")
.pipe($.get("js/eviflowplayer.js"))
.pipe($.get("js/evi.flowplayer.js", {}, function()
{
    W.EVI.FLOWPLAYER.init(elem.attr('id'));
});
