hidden field 'is null or not an object'

[Foehammer]

I've created a WYSIWYG HTML editor. I have an ImageButton whose
onClick event is supposed to set the value of a hidden form field
called txtHTML to the HTML content of an IFRAME called editor.

Here's the code that is supposed to set the value:
document.EditorForm.HTMLEditor_txtHTML.value =
editor.document.body.innerHTML;

I'm getting this error.
Microsoft JScript runtime error: 'document.EditorForm.txtHTML' is null
or not an object

Anybody have any ideas on this one?

Will

Hi Foehammer,

This is apparently your code.
Is this the exact error text for sure?

Note that one line lists _txtHTML while the other has txtHTML, these are NOT
the same members.

Hi

document.forms["FORMNAME"].FIELDNAME.value =
document.frames["IFRAMENAME"].document.body.innerHTML;

Or
<form name="blah">
<input type="hidden" name="myHidden">
<input type="image"
onclick="this.form.myHidden.value=document.frames["IFRAMENAME"].document.body.innerHTML">
</form>

Case sensitive

You may also want to check if the iframe is there and it's readyState:
if(document.frames["IFRAMENAME"])
{
if(document.frames["IFRAMENAME"].document.readyState == "complete") doIt();
else doSomethingElseLikeRe_CheckInXTimeAndGiveErrMsgAfterXTries();
}
else doSomethingElseLikeRe_CheckInXTimeAndGiveErrMsgAfterXTries();
