Last Updated : 12 Jul, 2023

The ajaxError() method in jQuery is used to specify a function to be run when an AJAX request fails.

Syntax:

$(document).ajaxError( function(event, xhr, options, exc) )

Parameters: This method accepts single parameter function which is mandatory. This function accepts four parameters which are listed below:

event: This parameter holds the event object.
xhr: It holds the XMLHttpRequest object.

The demo.txt file is stored on the server and it will load after clicking the change content button.
