javascript prevent default for keyup

Solution 1:

No. keyup fires after the default action.

keydown and keypress are where you can prevent the default.
If those aren't stopped, then the default happens and keyup is fired.

We can prevent the action by using following code snippet.

e.stopPropagation();
      e.preventDefault();  
      e.returnValue = false;
      e.cancelBubble = true;
      return false;

keyup fires after keydown/keypress. we can prevent default action in anyone of those events.

Thanks,
