Using the client script loader is very easy. Once you have downloaded the libraries and included them in your project you need to reference the JavaScript file Start.js. Start.js contains the client script loader functionality that can reference all the other script files: <script src="../Scripts/Start.js" type="text/javascript"></script> Once you have referenced the client script loader, you can then use its methods to load other scripts with the Sys.require() method (the following code references the new dataView component that you will look at shortly): Sys.require(Sys.components.dataView); The client script loader loads scripts in a very efficient and parallelized manner, taking care of resolving dependencies and ensuring that scripts are loaded only once. It even supports lazy loading and working with third-party libraries.

Note this is the format to load various controls from the AJAX toolkit
Note that each of these scripts has a .debug.js version and that the AJAX control toolkit now lives in the scripts/extended directory.
Specifying Script Directories
By default, the client script loader will load scripts from the same directory in which it is located, although you can modify it by specifying a new basePath property: Sys.loader.basePath = "../MyLocation/"; You can also specify a separate directory for jQuery scripts to be loaded from: Sys.scripts.jQuery.releaseUrl = "../jQuery/jquery-1.3.2.js"; Sys.scripts.jQuery.debugUrl = "../ jQuery /jquery-1.3.2.js ";
Loading Custom Scripts
You can also make use of the parallelization capabilities of the client script loader to load your own scripts with the loadScripts() method that accepts an array of script files to load: Sys.loadScripts(["../AnnoyingTrailingCursor.js", "../Scripts/HorribleFlashingDiv.js"]);
MICROSOFT AJAX LIBRARY
Lazy Loading
A good use of the loadScripts() method is to load scripts only when they are needed (lazy loading). For example, you might have a function that is rarely called and instead of forcing all users to have to download it you can load it only when you need to: function btnHardlyEverClicked_click() { Sys.loadScripts(["../Scripts/myFunction.js"], function() { myFunction(); }); }
AJAX Libraries Now Hosted by Microsoft
The Microsoft AJAX and jQuery libraries are now hosted by Microsoft s content delivery network (CDN). By using DNS trickery, script files can be served from a server local to the user, thus reducing download time and load on your server (not to mention your bandwidth bill). The following code shows how to reference the CDN version of the scripts. (The URL, version 0911, will probably change by release, so for the most up-to-date information, please refer to http://www.asp.net/ajax/cdn/.) <script src="ajax.microsoft.com/ajax/0911/start.js"></script>
ScriptManager EnableCDN
The ASP.NET ScriptManager control has a new Boolean property called EnableCdn that if set to true will serve scripts from the Microsoft CDN.
AJAX Toolkit Integration
The AJAX toolkit controls are now combined into the AJAX libraries. Apart from easier deployment, this feature also allows you to programmatically create them. The following example shows how to add the color picker control from the toolkit to a textbox programmatically (note that it wasn t necessary to reference any toolkit assemblies): <script src="./Scripts/Start.js" type="text/javascript"></script> <script src="./Scripts/Extended/ExtendedControls.js" type="text/javascript" type="text/javascript"></script> <script> Sys.require(Sys.components.colorPicker, function() { Sys.create.colorPicker("#txtChooseColor"); }); </script> <input id="txtChooseColor" />
MICROSOFT AJAX LIBRARY
Controls Now Exposed as jQuery Plug-ins
In this release, all the ASP.NET AJAX controls are exposed as jQuery plug-ins. So you can instantiate them using jQuery syntax, even making use of jQuery s chaining capabilities. The following code attaches an ASP.NET AJAX watermark control to a text box and an ASP.NET AJAX color picker: Sys.require([Sys.scripts.jQuery, Sys.components.watermark, Sys.components.colorPicker]); Sys.onReady(function () { $("#txtChooseColor").watermark("Choose a color", "watermarked").colorPicker(); });
DataView
One of the coolest controls in this release is the new DataView control. DataView allows you to easily define a template that can be bound to various types of data or services. WPF/Silverlight developers might notice some similarity with the binding syntax.
