javascript - Adding event handler to an iframe using JQuery

Question

I want to assign a keydown event handler to an iframe. Something similar to the pure JS:

document.getElementById('iframe_id').contentWindow.addEventListener('keydown',funcName, true);

I tried:

$(document.getElementById('iframe_id').contentWindow).keydown( function() {
   // my func
});

But it does not work.. Please help!

Answer 1

contentWindow is the iframe's window object. You want the iframe's document instead:

$(document.getElementById('iframe_id').contentWindow.document).keydown(function() {
    // my func
});

Note that I am not sure how jQuery reacts to elements from other windows/frames.
