Hi! I'm a rookie newbie wannabe Javascript Joker! :o There, now that that's out of the way, hopefully you'll forgive the stupidity of the following:

Some "professional" programmer left me with this code for my business, and although I'm trying to learn it, it seems like he is, too:

<script type="text/javascript">
function setList(url, cnt)
{
xmlHttp=GetXmlHttpObject()
if (xmlHttp==null)
{
alert ("Browser does not support HTTP Request")
return
}
url=url+"?"+cnt
url=url+"&sid="+Math.random()
xmlHttp.onreadystatechange=stateChanged
xmlHttp.open("GET",url,true)
xmlHttp.send(null)
}

function stateChanged()
{
if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete"){
document.getElementById('form').innerHTML= xmlHttp.responseText;
}
}

function GetXmlHttpObject()
{
var xmlHttp=null;
try
{
// Firefox, Opera 8.0+, Safari
xmlHttp=new XMLHttpRequest();
}
catch (e)
{
//Internet Explorer
try
{
xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
}
catch (e)
{
xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
}
}
return xmlHttp;
}
</script>
</head>

<body id="********" onload="setList('golfrounds.php', 'i='+document.getElementById('golfList').value)">

</div>
<div class="clear" ></div>

</div>

The problem is that when I try to make a change to the month, day, or year on the page, I get the "Object expected" error. I assume the missing object is setItemDate, but I wasn't sure how to create it. Anyone wanna throw me a bone...?

Can you post the functionality that you want when you change Day, Month and Year select lists. As you've mentioned there is no function - setItemDate in the code furnished in your post. It seems that there is a event attached to a non-existing event handler.

Before we go on, remember, there's no such thing as a dumb... yeah.

Anyway, the above-mentioned mess is supposed to describe simple dropdowns for an email form. It is one of several pages included in the form, all of which use setItemDate. I'm not sure why, since each page asks for its own dates. I'm not even sure at this point why setItemDate or any onChange commands need to be there at all. Despite the "object expected" error, the dates themselves all show up on the form in my inbox. Hope this is a lot more helpful than I thought it was.

I also got to thinking that maybe setItemdate was supposed to automatically detect the date and have the default option in the dropdown reflect it. It never worked from what I can tell. I removed the setItemdate functions from the code, and now I have no error message when I access the menu. I might still be missing something, however.
