 ## Ajax and Forms
 
-jQuery’s ajax capabilities can be especially useful when dealing with forms. 
-The [jQuery Form Plugin](http://jquery.malsup.com/form/) is a well-tested tool for adding Ajax capabilities to forms, and you should generally use it for handling forms with Ajax rather than trying to roll your own solution for anything remotely complex. 
-That said, there are a two jQuery methods you should know that relate to form processing in jQuery: `$.fn.serialize` and `$.fn.serializeArray`.

 ## Ajax Events
 
-Often, you’ll want to perform an operation whenever an Ajax requests starts or stops, such as showing or hiding a loading indicator. 
-Rather than defining this behavior inside every Ajax request, you can bind Ajax events to elements just like you'd bind other events.

 ## Overview
 
-The XMLHttpRequest method (XHR) allows browsers to communicate with the server without requiring a page reload. 
-This method, also known as Ajax (Asynchronous JavaScript and XML), allows for web pages that provide rich, interactive experiences.

-Ajax requests are triggered by JavaScript code; your code sends a request to a URL, and when it receives a response, a callback function can be triggered to handle the response. 
-Because the request is asynchronous, the rest of your code continues to execute while the request is being processed, so it’s imperative that a callback be used to handle the response.

-Most jQuery applications don’t in fact use XML, despite the name “Ajax”; instead, they transport data as plain HTML or JSON (JavaScript Object Notation).
