Ie11 $.ajax, Access is denied.

The same IE11, some can, some pop-up denied access. Other browsers do not eject access denied.

$.ajax code will be executed in multiple places,

1, if directly in the input box input, and then blur the event, you can $.ajax

2, if in other events, with JS to the input box, fill in the value, and then trigger the Blur event, then will be denied access!

So the key issue is that $.ajax is not allowed to execute in callback events in some versions of IE. Testing tomorrow is not the case!
