Can't capture delete key pressed in jQuery

Question

I'm executing the following code as suggested here.

$("#textBox").on("keyup", function (event) {
  foo(event.keyCode === 8 || event.keyCode === 64);
});

function foo(special) {
  console.log(special);
}

For BackSpace it works like a charm producing true. However, Del produces false. What's up with that?!

@StevenVondruska If you add an answer I will give you +1. :-) I respect you because you was so fast! — Ionică Bizău, Jul 10 '13 at 15:13
Side note: you should use `event.which` instead of `event.keyCode`, it normalizes `keyCode` and `charCode` — billyonecan, Jul 10 '13 at 15:14
@Johnツ eh, I should have posted as an answer instead. But Avitus did answer the question and no need for me to do the rep grab. Thanks for the shout out though! — Steven V, Jul 10 '13 at 15:15
I posted the answer about the same exact time you commented so feel free to answer. — Avitus, Jul 10 '13 at 15:19

It's because the keycode for delete is 46 not 64.

Hrmp... Well - what the {your favorite profanity here}! I meant 64. Can't the stupid computer understand what I mean?! I was about to yell at the idiot that posted 64 in the question I linked to. But apparently someone tries to make me look dumb and changed that just now. It **was definitely** 64 before...
