How to add onkeydown to body?

Question

In my index.html I have this code. I would need to add onkeydown event to that body in Main.onLoad().

Any idea how to do it?

Answer 1

Usually onkeydown can be attached to the elements which can receive focus. In some browsers you can gain focus to the document.body, but you can't rely on that. window is one of those elements which can gain the focus.

You can try to put the code below to the head section of your HTML code, after TVA is defined.

window.onkeydown = TVA.keyDown;

Or when using addEventListener():

window.addEventListener('keydown', TVA.keyDown, false);
