Unregistering from the JQUERY Keydown event

Question

I am trying to remove the keydown event that I have created using the following code:

$(document).keydown(function(e) {
    alert("Key Down");
});

when I am using the following code:

$(document).off('keydown');

it throws the following error:

Uncaught TypeError: Object [object Object] has no method 'off'

can someone point me to the correct way to un-register from the keydown event?

Answer 1

Unbind all keydown handlers from document:

$(document).unbind('keydown');

Or to make sure you only unbind that specific handler:

function myHandler(e) {
    alert("Key Down");
}

$(document).keydown(myHandler);
// later
$(document).unbind('keydown', myHandler);
