Using Javascript to load other external Javascripts
I have a library of JS code to load from a folder. Instead of typing the <script src='...'></script> lines one by one in the tag of the HTML document, is there a way of just link one Javascript file which organizes and automatically load other javascript files.
I know the Dojotoolkit is using this technique where only one JS file is loaded onto the client's computer, and once the code has been requested in the browser, 20 other JS code each with <script> tag are generated.
This is the code you need:
// Create
var bodyEl = document.body;
var scriptEl = document.createElement('script');
scriptEl.type = 'text/javascript';
scriptEl.src = url;
bodyEl.appendChild(scriptEl);
Put that into a function, have an array of all the javascript files, and call that function for each file.
Benefits of using the DOM is that document.write doesn't work in some funny instances. More about this here: document.write() vs inserting DOM nodes: preserve form information?
Code taken from the open source project jQuery Sparkle: http://github.com/balupton/jquery-sparkle/blob/master/scripts/resources/jquery.appendscriptstyle.js#L103
一个简单的方法来做到这一点：
document.write("<script type='text/javascript' src='b.js'></script>");
Try use requireJs, he have very userful functions
