How to remove an eventhandler document.onkeydown?

Question

I have this code, I would need programmatically overridde or remove onkeydown from document (for example using a simple condition)

document.onkeydown = function (f) {
    myMethod();
};

Any idea how to do it?

Answer 1

document.onkeydown = null

You could use jquery to do your event handeling for you, the method you use is less commonly used and doesn't allow multiple subscribers.

Look at the documentation here:

http://api.jquery.com/on/

example:

$(document).on("keydown", function(){
    doStuff();
})
// unsubscribe all handlers
$(document).off("keydown");
