Default Need help with onchange of DOM element

Hi,

I'm trying to dynamically create and add an input box with an anonymous Javascript function for handling the onchange event. Here is the DHTML code I'm using:

var myInput = document.createElement("input");
myInput.type = "text";
myInput.id = "myInputId";
myInput.onchange = function() { alert("foo"); }

(I am adding the input appropriately to a td and tr within a table)

However, when I change the contents I'm not getting the alert I expect. I've looked through chapter 6 of the book (after having read it) and can't find anything to help me out in this situation.

What am I doing wrong?

Thanks,
John

onchange fires when the text has changed *and* the focus is lost. It doesn't fire as the user types.

Yes, sorry. I guess my original question wasn't that clear. I meant to say that when I enter text *and* tab off, the event doesn't fire.

Thanks,
John
