access web controls in a User control via Javascript

[george d lake]

Hi,
I have a user control that has a series of web controls in it.
I need to access the web controls from the parent page via javascript. No, I
have done this in the past but know I am having problems. It just will not
find the obj on the javascript side.

here is some code (HTML output):


<span id="ucUntouchedItems_spUntouched" style="CURSOR:hand;COLOR:#003399"
onClick="toggleBB(ucUntouchedItems_divUntouched,
ucUntouchedItems_imgUntouched,ucUntouchedItems_htbUntouched)">
<img id="ucUntouchedItems_imgUntouched"
src="/TicketSystemV2/images/collapse.gif" border="0"
style="border-style:None;height:16px;width:16px;" />
<span id="ucUntouchedItems_lbGridName">Untouched Items (4)</span><br>
</span>
<input id="ucUntouchedItems_htbUntouched" type="hidden" />
<div id="ucUntouchedItems_divUntouched" style="DISPLAY:none">

If I run at the buttom of the page:

<script language=javascript>
alert(ucUntouchedItems_htbUntouched);
alert(ucUntouchedItems_imgUntouched);
alert(ucUntouchedItems_divUntouched);
</script>

I get Errors on the first 2.

Any ideas why? I am missing something???

You may want to try document.getElementByID(...) to get a reference to that
object, and then grab the value attribute of that object. ie:

var htbUntouched = document.getElementByID("ucUntouchedItems_htbUntouched");
if (htbUntouched != null) {
window.alert(htbUntouched.value);
}
