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.

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.

This selects an element using its ID.


jQuery object

This refers to the current jQuery object.


jQuery method

This adds the specified CSS class to each matched element.


jQuery event

This is fired when a key is released. It corresponds to the JavaScript keyup event.


JavaScript property

This returns the length of the string.


jQuery event binder

This attaches an event handler for one or more events to the matched elements.

.prop(propertyName) or

.prop(propertyName, value)

jQuery method

This returns the value of the specified property for the first matched element or sets the value of the specified property for all matched elements.
