document.createEvent parameter for change event

hi ... here is a short example for the usage:

Code:

<html>
    <head>
        <script type="text/javascript">
            function raiseEvent() {
                var ele = document.getElementById('myNode');
                ele.onchange = function() { alert(this.value); };

                var e = document.createEvent('HTMLEvents');
                e.initEvent('change', true, true);

                ele.dispatchEvent(e);
            }
        </script>
    </head>
    <body onload="raiseEvent();">
        <input type="text" value="bar" id="myNode" />
    </body>
</html>

i never used it before and the documentation is quite ... lets say ... short ;) ... but the above example works. it would even work with UIEvents, where the event.initUIEve nt() method is to be used and you could pass more params ...

kind regards

Most of the time it's my JavaScript that's not working, but in this case it was my .NET code!

I forgot to indicate that the <select> should post back to the server when its selected index changed..... and that's why it wasn't getting back to the server after raising the event!
