Is it possible to blur input without firing the blur event?

Question

I'm running into errors because an event binder in jQuery is attached to 'keyup' and 'blur'. But when I remove the input from the DOM that seems to fire the blur event, thus re-running the handler on a non-existent DOM input.

Answer 1

You can validate this in the handler when the event is fired

if (this && $(this).length > 0 ) { /*do stuff*/ }

Answer 2

If the event listener was added with jQuery, you could use unbind:

$(/* ... */).unbind('blur');

In newer versions of jQuery, off is preferred:

$(/* ... */).off('blur');
