Hide Page Controls on Page Load with JavaScript

Question

Good Morning, I am trying to use a peice of code that I found on another thread:
HTML Header
<script language="JavaScript1.1" type="text/javascript">
function setDisabled(PageItem) {
document.getElementById(PageItem).style.visibility = "hidden"
</script>
HTML Body Attribute
onLoad="javascript:setDisabled('P36_COMMS1_0');
The code works if I change the "onLoad" to "onClick" and click the control. But when I use it as written, it doesn't trigger when the page loads. Does anyone have any ideas?
Here is the original thread: http://forums.oracle.com/forums/thread.jspa?messageID=2760790&#2760790, but the thread didn't really relate to my question.

Hi Donald,
As the code is within a function block it is has to be called by something when the page loads.
The simplest method would to be ensure that you have a piece of javascript at the bottom of the page (ie, underneath the function and the field it refers to):
&lt;script type="text/javascript"&gt;
setDisabled('itemname');
&lt;/script&gt;When the browser loads this piece, because you haven't wrapped it within a function block, the code is executed immediately (hence needing to be loaded after the function and the field).
