Handling cross-browser key events with jQuery

Another little copy-paste code fragment from the house of jQuery :) If you need to od different things on keydown event, use this basic structure, so it will be cross-browser friendly:

1 2 3 4 5 6 7 8 9 10 11 12

jQuery(document).keydown(function (e) { var evt=(e)?e:(window.event)?window.event:null; if(evt){ var key=(evt.charCode)?evt.charCode:((evt.keyCode)?evt.keyCode:((evt.which)?evt.which:0)); // the key specific code comes here: console.log(key); } });

I've tested it on Chrome, FF and IE9-10, and it works well.
