Question

I have a function that is called by a dropdown change. It is possible that the function is running and the user changes the dropdown.

If that happens I want the function that is running to stop.

Ex.

$('.txtCategory').change(function(){
    ajaxPost('para', 'meters').stop(); //doesn't work
    $('#Submit').attr('data-check', 'on');
    $('#Submit').val('Stop Checking');
});

Is this possible?

Thanks in advance!

This isn’t possible for a simple reason : your script execution happens on only one thread, only one function can run at a time.

Any callback responding to a local event or to a query won’t be called until the current function has finished execution.
