This article mainly introduces the use of ajaxError (), has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

.ajaxError () description: registers a callback handler, which is an Ajax Event, when an Ajax request goes wrong.

Whenever an Ajax request goes wrong, jQuery triggers the ajaxError event, and at this point all handlers are registered and executed using the .ajaxError () method. Note: the handler processor here invokes cross-domain scripts and cross-domain JSONP requests.

Observe this method and establish a basic Ajax load request:

Trigger

Bind event handlers on document:

$(document) .ajaxError (function () {

("div.log") .text ("Triggered ajaxError handler.")

})

Now we can use any jQuery method to build an Ajax request:

$("button.trigger") .click (function () {

$("div.result") .load ("ajax/missing.html")

})

This message is displayed when the user clicks the button and the Ajax request fails because the requested file does not exist.

But starting with jQuery 1.8, the .ajaxComplete () method can only be bound to document elements.

Note that this paragraph has been deleted from the original text on the official website: because .ajaxComplete () is executed as a jQuery object instance method, we can use the this keyword as the specified element in the callback function.
