To lunter@interia.pl(bug opener):
See onmouseover attribute content of "el" by attached HTML.
(1) Load HTML, and click "Check" button. (<span onMouseOver="alert(...);">)
(2) Click "Change", and click "Check". (el.onmouseover=function()...};)
onXXXX="script_code" in HTML tag is different from registration of event handler via JavaScript.
As seen in test result, when onXXXX="script_code;", "function(event) { script_code; }" is registered by Firefox/Seamonkey.
(This is the reason why event object is accessed via variable name of "event".)
You *have to* use following statement, if you want to register event handler by yourself.
> document.getElementById('el').onmouseover=function(e){alert(e['type']);}

Another way:
document.getElementById("el").setAttribute("onMouseOver","alert(event['type']);");

The code in comment 0 assumes IE's window.event model of passing around events. If you had an |event| argument to your event handler, things would work fine.
