ajaxError and ajaxComplete firing twice upon abort

in Using jQuery • 9 years ago

I was aborting an ajax request inside ajaxSend function, and I noticed that the ajaxComplete and ajaxError global event handlers bound to document are being called twice, and in their second execution they throw TypeError: Cannot read property 'send' of undefined.

When aborting ajax calls outside of ajaxSend, it behaves normally.

Is it supposed to work like this?

Tested using 1.9.1, 1.11.1, 2.1.1

JSFiddle

$(document).ajaxSend(function( e, jqXHR ) {
$("body").append('aborting ajax... ');
jqXHR.abort();
});
$(document).ajaxError(function( e, jqXHR, opts, err ) {
$("body").append('global ajax Error callback (status: '+ err +') ')
});
$(document).ajaxComplete(function( e, jqXHR ) {
$("body").append('global ajax Complete callback (statusText: '+ jqXHR.statusText +') ');
});
$.ajax({
url: '',
error: function() {
$("body").append('specific ajax Error callback ');
},
complete: function() {
$("body").append('specific ajax complete callback ');
}
});
