Enter `keyCode(13)` works fine on all browsers. 

Space bar `keyCode(32)` I tested on Chrome works fine but not responding on Firefox. I used the following code:

```
<script type="text/javascript" >
    function enterPressed(evn) {
        var e_id = $('e_id').value;
        var e_fname = $('e_fname').value;
        var e_role = $('e_role').value;

        if (window.event && window.event.keyCode == 13) {
            Monitor.Order.assign(e_id, e_fname, e_role);
        } else if (evn && evn.keyCode == 13) {
            Monitor.Order.assign(e_id, e_fname, e_role);
        } else if (evn && evn.keyCode == 32) {
            Monitor.Order.updateStatus('COOKED');
        }                       
    }
    document.onkeypress = enterPressed;     
</script>

```

Why is this not working in Firefox when it works in Chrome?
