View Full Version : How do I get a failure() called on an Ajax request?

When I write ajax requests, what do I echo out to have the failure function called? I have tried { success: false} and { failure: true}
It seems to work with success false when I do it from a form submit but not when I try it from an ajax request. I am using 3.1

The failure function will be called if there is a server-side request failure, and not if you return success: false. Try out a request with an invalid URI.

Modify your Ajax call to call some file that does not exist on the server such as noFile.php (which does not exist) then your failure: // will get called

If you supply a:

{"success": false}

This means the "server" response has passed. Which will not fire the failure callback, which only fires only when there is a server exception.

What you need to do, in this scenario is to check the success property of the JSON object in success.

Inside your Ext.Ajax.request

success: function (response, options) {

var obj = Ext.decode(response.responseText);
if (obj.success)
// Success
// Fail
