jQuery do stuff when a specific key is pressed

Question

I would like to play the animation "down" when i press down arrow key.

$(document).bind("keydown", function(event) {
   $('#down').toggleClass('down');
});

Also how can i have it not toggled?

Answer 1

Use event.keyCode like following.

$(document).bind("keydown", function (event) {
    if (event.keyCode == 40) { //40 is the keyCode of down arrow key
        $('#down').toggleClass('down');
    }
});
