Overview of this book

jQuery is a lightweight JavaScript library that has changed the landscape of client scripting in web applications. Developed by John Resig in 2006, it has taken the web by storm because of its cross-browser compatibility and the ability to get more done with less code. It has gained popularity with ASP.NET developers and is now distributed with Visual Studio and the NuGet package manager. ASP.NET jQuery Cookbook explores the wide range of utilities that the jQuery library provides. It teaches you the nitty-gritty of plugging in these features in ASP.NET web applications. It covers every aspect of interfacing the library, right from downloading and including jQuery on web pages to selecting controls, handling events, and creating animations. This book also walks you through DOM traversal and manipulation in ASP.NET and then through visual effects and graphics in ASP.NET sites. It explores advanced features such as posting AJAX requests and writing plugins. It will provide you with all the information you need to use this library confidently with ASP.NET.

Providing method chaining

Chaining more than one method is a very useful feature when programming in jQuery. Chaining is possible since most jQuery methods return an object allowing the calling of other methods on the returned object. Since the child methods are executed in the returned object instead of the entire DOM, the code runs faster. This allows you to write code, which is not only shorter but also faster.

The plugin that we have worked with so far does not support chaining. In this example, let's modify the plugin to include this feature.

The programming constructs used in this example are summarized as follows:





jQuery function

This refers to the jQuery function. $ is an alias for jQuery.


jQuery selector

This selects an element based on its ID.


jQuery object

This refers to the current jQuery object.


jQuery function

This merges the contents of two or more objects into the first object.
