ajax fails when page navigate away

[[email protected]…]

if ajax takes a little longer time, during ajax call, if user click another hyper-link to navigate away, the ajax 'fail handler' will be called. As the code below, if page navigate away before ajax call completes, the fail handler will be called.

function timeConsumingTest(){

$.post('XXX', function(data, status, xhr){

alert(data);

}).fail(function(xhr, status, thrown){

alert("error occured");

});

}

I think it is a bug, and how to sovle it? this bug can be reappeared both in chrome and firefox.

If you do an asynchronous request that is the way the XHR object works.
