Swap Enter Key for Tab Key

Question

So I've got this javascript:

<script type="text/javascript">
    function OnKeyPress() {
        var charCode = window.event.keyCode;
        if (charCode == 13) {                
            window.event.keyCode = 9;
        }
    } document.onkeypress = OnKeyPress;
</script>

The idea is to catch an enter key press, and switch it to tab key press. And it half works - it catches the enter key. But it doesn't make it register as a tab key. I've tried using other keycodes as well (18 for alt) to confirm I wasn't just not seeing the tab happen.

Can anyone see what the problem is? Working in ASP.NET fwiw.

Thanks!

You can't change the keyCode and have it trigger that event instead. It's just a captured value at that point. You might be able to obtain the effect by calling a function that simulates the desired key press event and canceling the current event instead.

so you're suggesting dropping this bit 'window.event.keyCode = 9; ' and replacing it with a function call? Can you recommend a function that would produce the desired result? – Karl Feb 27 '14 at 19:44
Depends on what the desired results are. There's actually a similar question here: http://stackoverflow.com/questions/17482036/how-to-simulate-tab-key-with-enter-key-on-javascript Is that what you are trying to do also? – Matt Pileggi Feb 27 '14 at 19:46

You'll have to create the event handler for it.

Take a look:

If you're in a hurry you can use jQuery to do it. Use the .trigger function. It will be a lot simpler, but doing it in pure javascript is far better from the learning perspective. ;) – Renato Galvones Feb 27 '14 at 19:41
