If I want to change a hidden form element (curtime) contained within a form (form1) on a page (IMclient.htm) to a variable named 'timenow'

How do I do it?

PS I always give stars for GOOD answers so don't be backwards in coming forwards!!!!

What's the problem?

document.form1.curtime.value = timenow;


If the page is a frame inside a frameset:

parent.frame_name.document.form1.curtime.value = timenow;

Well you were right. I was being silly - 1 slight case-sensitive error threw it out.
but you answered another question I had... why I just spent £30 on a JavaScript Bible I'll never know

Thank you

well heres one for you then... earn it :)

I want to change a form select array from within an IFRAME embedded next to the form.
The select is named 'touser' and sits in the form 'form1'

The IFRAME source is CGI generated, and the CGI code I have is:

while($i < $usernum){ // count from the top of the list
// .... here gets new variable
echo &quot;parent.document.form1.touser[$i].text='$variable';\n&quot;;
++$i;
}

Which produces:

parent.document.form1.touser[0].text='hello';

I can assure you that the <script language='JavaScript'> headers are intact and proper, I am 99% certain the failure lays within the above line.
Can you give me the proper DOM reference?

I don't like ifames and never use them, but I think it should be this:

window.top.document.form1.touser[0].text='hello';

This is pasted directly from the IFRAME source.

<html>
<head>
<script language=&quot;JavaScript&quot;>
function upDate(){
window.top.document.updater.touser[0].text='tels';
window.top.document.updater.touser[1].text='paul';
window.top.document.updater.touser[2].text='test';

}</script>
</head>
<body onLoad='upDate()'>
</body>
</html>

...But I get no joy :(

the page source, for your reference is:

<html>
<head>
<title>Untitled Document</title>
<meta http-equiv=&quot;Content-Type&quot; content=&quot;text/html; charset=iso-8859-1&quot;>
</head>

<body bgcolor=&quot;#FFFFFF&quot; text=&quot;#000000&quot; onLoad=&quot;clock()&quot;>
<table width=&quot;400&quot; border=&quot;0&quot; cellspacing=&quot;0&quot; cellpadding=&quot;0&quot; height=&quot;150&quot; bgcolor=&quot;#CCCCFF&quot;>
<tr>
<td width=&quot;199&quot; align=&quot;center&quot; valign=&quot;middle&quot; height=&quot;174&quot;>
<table width=&quot;90%&quot; border=&quot;0&quot; cellspacing=&quot;0&quot; cellpadding=&quot;0&quot; height=&quot;151&quot; bgcolor=&quot;#FFFFFF&quot;>
<tr>
<td height=&quot;139&quot; valign=&quot;top&quot;><iframe src=&quot;&quot; name=&quot;messwin&quot; scrolling=&quot;yes&quot; width=&quot;100%&quot; height=&quot;100%&quot;></iframe></td>
</tr>
</table>
</td>
<td width=&quot;201&quot; valign=&quot;top&quot; height=&quot;174&quot;>
<form name=&quot;updater&quot; action=&quot; method=&quot;get&quot; target=&quot;messwin&quot;>
<p><br>
type your message here
<input type=&quot;text&quot; name=&quot;message&quot; value=&quot;&quot;>
</p>

// this is the select array I want to change

<select name=&quot;touser&quot;>
<option>user</option>
<option>tels</option>
<option>paul</option>
</select>

<input type=&quot;submit&quot; name=&quot;send&quot; value=&quot;send&quot;>
<input type=&quot;hidden&quot; name=&quot;method&quot; value=&quot;update&quot;>
<input type=&quot;hidden&quot; name=&quot;username&quot; value=&quot;paul&quot;>
<input type=&quot;hidden&quot; name=&quot;curtime&quot; value=&quot;23:59:59&quot;>
</form>

</td>
</tr>
</table>
</body>
</html>

Here is an error:

window.top.document.updater.touser[options][1].text='paul';

Each <select> has an array of <option> elements, and each one of them should be accessed as select.options[] array item.

sorry,
this is the correct syntax:

window.top.document.updater.touser.options[1].text='paul';

(you shouldn't hurry when you post)

Nope. didn't work.
Heres the cgi output

<html>
<head>
<meta http-equiv=&quot;refresh&quot; content=&quot;10&quot;>
<script language=&quot;JavaScript&quot;>
function upDate(){
window.top.document.updater.touser[options][0].text='tels';
window.top.document.updater.touser[options][1].text='paul';
window.top.document.updater.touser[options][2].text='test';

}</script>

I have definately confirmed - everything else on the page is well formed and not in the slightest erroneous.
