Overview of this book

jQuery is a lightweight JavaScript library that has changed the landscape of client scripting in web applications.

Retrieving data from a Web API

A Web API (Web Application Programming Interface) is a HTTP API that is created using the .NET framework. It uses the HTTP protocol to return data. Since HTTP is available universally across a wide range of platforms, these APIs can be used on Web and mobile platforms and across various devices.

In this example, we will use jQuery Ajax to post a request to a Web API. The constructs used in this example are summarized in the following table:





jQuery selector

This selects an element based on its ID.


jQuery selector

This selects all elements with the specified HTML tag.


jQuery function

This loads the JSON data from the server using the HTTP GET request.


jQuery method

This inserts content at the end of each matched element.


jQuery event

This is fired when you click on an element. It corresponds to the JavaScript click event.
