jQuery键和鼠标单击

Question

My code:

<input class="quantity" type="text"  value="33000">
<script>    
   $(document).ready(
   $('.quantity').keyup(function (event) {
       alert('up');
       MyVeryImportantValidate($(this), event.key)                  
   });
   ..
</script>

My problem, if introduced into the Input still holding the keys and mouse make click on any other element in page... event keyup does not work.

Answer 1

I think the documentation in jquery states it clearly, it is going to the item that has focus.

http://api.jquery.com/keyup/

The keyup event is sent to an element when the user releases a key on the keyboard. It can be attached to any element, but the event is only sent to the element that has the focus. Focusable elements can vary between browsers, but form elements can always get focus so are reasonable candidates for this event type.

In fact the focus is lost even on holding a key down in this input text area. If I hold down the a letter key it repeats until I click outside it changing the focus.
