Is there a jQuery plugin that normalizes browser key codes?

Question

Is there a jQuery plugin that normalizes key codes cross-browser? Meaning, if you press a certain key, then you are guaranteed to get the same key code for every browser that you test in?

It's called [`event.which`](http://api.jquery.com/event.which/). — gen_Eric, Dec 18 '12 at 20:10

No, however, it is built into jQuery!

$("element").on("keypress",function(e){
    console.log(e.which);
});

The which property of the event object is defined for key and mouse events in most browsers, but not IE < 9. jQuery, however normalizes this support: e.which (Thanks @RocketHazmat for pointing this out)

$(this).keyup(function(e) {
    var code = e.which;
    ...
}

Why do you do that? `The event.which property normalizes event.keyCode and event.charCode. It is recommended to watch event.which for keyboard key input.` http://api.jquery.com/event.which/ – gen_Eric Dec 18 '12 at 20:12
So you place `e.keyCode` to account for IE <= 8? – Lester Peabody Dec 18 '12 at 20:14
`e.which` works fine in IE8. – gen_Eric Dec 18 '12 at 20:14
For ie support see - http://stackoverflow.com/questions/10315260/internet-explorer-showing-e-which-as-undefined – benedict_w Dec 18 '12 at 20:15
@benedict_w: jQuery adds `e.which`, it's not *natively* in IE < 9. – gen_Eric Dec 18 '12 at 20:16
I see @RocketHazmat - good call – benedict_w Dec 18 '12 at 20:17
@benedict_w: Your example is using jQuery already, so `|| e.keyCode` is completly useless. – gen_Eric Dec 18 '12 at 20:19
