onKeyUp event not firing...or just bad code?

[Brent]

The code below correctly sets an iframe to be editable, and then tries
to attach an "onkeyup" event to the iframe. Instead of doing that,
however, it generates a cryptic "Object required" error in Explorer 7,
and doesn't seem to do anything at all in Firefox. Am I missing
something really basic?

Thanks for any help.

if(thisEl.body.contentEditable)
{thisEl.body.contentEditable = true;}

}
catch(e)
{
alert(e);
}
thisEl.body.style.fontFamily = "verdana, arial, helvetica, sans-
serif";
thisEl.body.style.fontSize = "12px";
thisEl.body.style.margin = "1px";

thisEl.onkeyup = checkKeys; //<--doesn't seem to register the
event
}

function checkKeys(e)
{

var event = e ? e : window.event;
var KeyID = event.keyCode;
alert(KeyID);
}

In IE, you are assigning the keyup listener to the document in the
IFRAME (as you must) but the code in the assigned function is looking
for the event in the window that contains the IFRAME, which is not the
window in which the events are happening.

Why are you including meaningless text in your posts, and most
especially, why have you attributed that text to me?

thisEl.document.body.onkeyup ?

What (and why)?
