assigning innerHTML to variable
here's an interesting one i think:
i'm trying to do this:
var theString = mytext.document.body.innerHTML;
alert(theString);
where mytext is an IFRAME element...the only IFRAME element on the page...and although i keep getting the alert with the innerHTML in it exactly like i want (for a test)...i also get an error that says: object required.
now the interesting thing is that i've done this same thing other places in the app and it's worked fine! hmmm....
----------
my html looks like this:
<td><IFRAME class="mytext" width="<%= strWidth %>" ID="mytext" height="100%"></IFRAME></td>
and my javascript looks like this:
// Initialize everything when the document is ready
var YInitialized = false;
function document.onreadystatechange()
{
YInitialized = true;
var i, s, curr;
var newEvt;
mytext.document.open();
mytext.document.write("<BODY bgcolor=\"#<%= strColor %>\" >");
mytext.document.write("<%= jsString %>");
mytext.document.write("</body>");
mytext.document.close();
mytext.document.designMode="On";
mytext.focus();
healBorders();
var theString = mytext.document.body.innerHTML;
alert(theString);
}
you can see that i've saved HTML code in a field in a db and upon loading this page i write it to the IFRAME using asp and javascript...
-------------
any help would be real, real nice.

the answer...
well...it wasn't a stupid question...i just didn't know the intricacies of "DesignMode"...
apparently the reason the original code fragment wouldn't work:
document.saveForm.html.value = mytext.document.body.innerHTML;
was because previous to this i also had this line of code:
mytext.document.designMode="On";
and according the the documentation from microsoft on "designmode" (see below)...of course it wouldn't work!
in the other places in my code where i had the original statement designMode was Off. go figure.

Remarks - Microsoft
You can use the designMode property to put Microsoft® Internet Explorer into a mode where you can edit the current document.
While the browser is in design mode, objects enter a UI-activated state when the user presses ENTER or clicks an object that has focus, or when the user double-clicks the object. Objects that are UI-activated have their own window within the document. You can modify the UI only when the object is in a UI-activated state.
You cannot execute script when the value of the designMode property is set to On.

situation vindicated.
(i hope this helps somebody, somewhere, sometime!)
