handling event in Firefox

Question

I have the following which works fine in Chrome 22 but is giving me an error in Firefox 16:

$('#search-query').on('keyup',function(){
  e=window.event;
  if(e.keyCode===13){
    alert('that was a return');
  }

How would I make this work in a cross-browser way?

thx

Answer 1

use jQuery wrapper event. firefox don't support window.event

$('#search-query').on('keyup',function(e){

  if(e.keyCode===13){
    alert('that was a return');
  }

Answer 2

Firefox does not support window.event Try this instead

$('#search-query').on('keyup',function(e){
  var evt = e || window.event;
  var keyPressed = evt.which || evt.keyCode;
  if(keyPressed ===13){
    alert('that was a return');
  }
});
