For example, this can be used to set, Only applies when the "script" transport is used. If jsonp is specified, $.ajax() will automatically append a query string parameter of (by default) callback=? In response to a successful request, the function's arguments are the same as those of .done(): data, textStatus, and the jqXHR object. Allow the request to be successful only if the response has changed since the last request. The key represents the name of the attribute and the value is the attribute's value. An object of fieldName-fieldValue pairs to set on the native XHR object. This processing can be circumvented by setting processData to false. .ajax().fail(function(jqXHR, textStatus, errorThrown){});

This header tells the server what kind of response it will accept in return. A success callback that gets invoked upon successful completion of an Ajax request.

If this object is provided it will force the use of a script-tag transport. It is often unnecessary to directly call this function, as several higher-level alternatives like $.get() and .load() are available and are easier to use.

It can be JSON object, string or array.

A set of key/value pairs that configure the Ajax request.

In the above example, first parameter is a url which is used to submit the data.

The "A" in AJAX is asynchronous meaning that it happens while the rest of code carries on. The async option to $.ajax() defaults to true, indicating that code execution can continue after the request is made.

Data to be sent to the server. Default is "application/x-www-form-urlencoded; charset=UTF-8", which is fine for most cases. This value will be used instead of 'callback' in the 'callback=?' If you explicitly pass in a content-type to, This object will be the context of all Ajax-related callbacks. Use this to set custom headers, etc.
