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 its ability to get more done with less code. The library is supported by an active community of developers and has grown significantly over the years. Using jQuery eases many client scripting tasks, such as event handling, embedding animations, writing Ajax enabled pages, among many more, and adds to the interactive experience of the end user. Its extensible plugin architecture enables developers to build additional functionalities on top of the core library.

Learning jQuery and using it in ASP.NET applications is an indispensable skill for ASP.NET developers. This book attempts to impart this skill by exploring diverse recipes for fast and easy solutions to some of the commonly encountered problems in ASP.NET 4.6 applications.

What this book covers

Chapter 1, Getting Started with jQuery in ASP.NET, describes recipes to download and include jQuery in ASP.NET 4.6 Web and MVC applications. It discusses the CDN, NuGet Package Manager, as well as debugging the jQuery code in Visual Studio.

Chapter 2, Using jQuery Selectors with ASP.NET Controls, describes various jQuery selectors that can be used to manipulate ASP.NET controls. These selectors can select controls based on the ID, CSS class, HTML tag, attribute, or position in the document.

Chapter 3, Event Handling Using jQuery, describes recipes to handle different types of events, such as mouse, keyboard, and form events. It also explains event delegation and detaching of events.

Chapter 4, DOM Traversal and Manipulation in ASP.NET, describes techniques to traverse the document, such as accessing parent, child, or sibling elements. It also teaches manipulation strategies to add and remove elements at runtime.

Chapter 5, Visual Effects in ASP.NET Sites, discusses recipes to create different types of animation effects on ASP.NET controls, such as Panel, AdRotator, TreeView, Menu, and GridView. Effects such as enlarging, sliding, and fading are covered in this chapter.

Chapter 6, Working with Graphics in ASP.NET Sites, discusses recipes to work with images and explains effects, such as zooming, scrolling, and fading on images. Utilities such as image gallery, image preview, and 5-star rating control are also explored in this chapter.

Chapter 7, Ajax Using jQuery, explains how Ajax calls can be made to page methods, web services, WCF services, Web API, MVC controllers, and HTTP handlers.

Chapter 8, Creating and Using jQuery Plugins, demonstrates how plugins can be created and included in projects. It also describes how to use the Node Package Manager (NPM) and Bower to download and manage third-party plugins.

Chapter 9, Useful jQuery Recipes for ASP.NET Sites, summarizes the book with diverse recipes to solve common real-world problems. You can find this chapter at:

Who this book is for

This book is for ASP.NET developers who want to use jQuery to write client scripts for cross-browser compatibility. No prior knowledge of ASP.NET or jQuery is expected, and every recipe is self-contained and explained in an easy-to-follow manner. The code samples in this book are provided in both C# and VB. Familiarity with Visual Studio and MS SQL Server is preferred, but not compulsory.


In this book, you will find several headings that appear frequently (Getting ready, How to do it..., How it works..., There's more..., and See also).

To give clear instructions on how to complete a recipe, we use these sections as follows:

Getting ready

This section tells you what to expect in the recipe, and describes how to set up any software or any preliminary settings required for the recipe.

How to do it…

This section contains the steps required to follow the recipe.

How it works…

This section usually consists of a detailed explanation of what happened in the previous section.

There's more…

This section consists of additional information about the recipe in order to make the reader more knowledgeable about the recipe.

See also

This section provides helpful links to other useful information for the recipe.


In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "On the download page, there is also a map file available with the extension. Sometimes, when bugs appear in the production environment necessitating troubleshooting, the use of the minified file for debugging can be difficult."

A block of code is set as follows:

Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs)
  ScriptManager.ScriptResourceMapping.AddDefinition("jquery", New ScriptResourceDefinition() With {
  .Path = "~/Scripts/jquery-2.1.4.min.js",
  .DebugPath = "~/Scripts/jquery-2.1.4.js",
  .CdnPath = "",
  .CdnDebugPath = "",
  .CdnSupportsSecureConnection = True,
  .LoadSuccessExpression = "window.jQuery"})
End Sub

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

<asp:ScriptManager ID="ScriptManager1" runat="server" EnableCdn="true">
    <asp:ScriptReference Name="jquery"  />

Any command-line input or output is written as follows:

bower install jquery-validation

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Click on the Download jQuery button (highlighted in the preceding screenshot) on the right-hand side of the page. This opens up the download page with the list of available files."


Warnings or important notes appear in a box like this.
