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?

type attribute for completeness.A simple way to do that:
document.write("<script type='text/javascript' src='b.js'></script>");
document.write is generally strongly deprecated. The same effect can be achieved by adding a <script> tag to the document.
document.write isn't deprecated. It's in the HTML 5 spec for a start: w3.org/TR/html5/embedded-content-0.html#dom-document-write<script> element to the document does not have the same effect: using document.write is synchronous (as is including a <script> element in HTML) while adding a <script> element using DOM methods is asynchronous. The synchronous approach has advantages, for example being guaranteed to have loaded before scripts that appear after it in the document.Try use requireJs, he have very userful functions
