return (/^[0-9]+$/.test(val));
}

What errors do you get? Do you see either alert? Have you tried looking in the JS console in Firefox or using Firebug to see if any errors are thrown?

I think I know what the problem is. Put the function call onkeyup, not onkeydown. Onkeydown, you are checking BEFORE the current pressed key's value is entered.

Besides that, all looks good (to me at least)
