JS: How to detect whether cursor is in textfield

html, javascript, shortcut

Solution

window.onkeydown = function(e){
  if ( e.target.nodeName == 'INPUT' ) return;

  handle_shortcut();
};

Problem

I want to use some letters ( keys ) as shortcut for some actions in javascript. I want to check whether the cursor is focused on any textfield, form input, etc. so that the shortcut action will be canceled when user is typing something in a form or textfield. For example, i want an alert() to be executed when user presses 'A'. But if the user is typing some text in a textarea like 'A website' then he will be pressing 'A', this time alert() should not be executed.
