determine which key is pressed

Question

How to determine which key is pressed in javascript?

Answer 1

In jQuery:

jQuery(window).live('keydown', function(e) { 
  var keyCode = e.keyCode || e.which; 

  //do stuff with keycode
  } 
});

Normal:

document.onkeyup = KeyCheck;       

function KeyCheck(){

   var KeyID = event.keyCode;
   //do stuff
}
