The ajax() method in jQuery is used to perform an AJAX request or asynchronous HTTP request. AJAX is an acronym standing for Asynchronous JavaScript and XML and this technology helps us to load data from the server without a browser page refresh.
If you are new to AJAX, I would recommend you go through our Ajax Tutorial before proceeding further.
JQuery is a great tool that provides a rich set of AJAX methods to develop next-generation web applications.
Syntax:
$.ajax({name:value, name:value, ... })
Here is the description of all the parameters −
- URL − The URL of the server-side resource to which the request is sent. It could be a CGI, ASP, JSP, or PHP script which generates data dynamically or out of a database.
- data − This optional parameter represents an object whose properties are serialized into properly encoded parameters to be passed to the request. If specified, the request is made using the POST method. If omitted, the GET method is used.
- callback − A callback function invoked after the response data has been loaded into the elements of the matched set. The first parameter passed to this function is the response text received from the server and the second parameter is the status code.
