posting content to an iframe

[mike]

I have a page with a form as follows:

<form name="updfrm" method="post" action="update_db.cfm">
<input type="text" name="myfield" value="stuff">
<button onclick="sub_this();">press here</button>
</form>

normally I would either 1) let this form post to this window, or 2)
open a window and post to it.

I'd like to try posting that using an iframe.

So, I create that iframe in the same page as the form like:

<div style="display:none">
<iframe src="" id="update_iframe" name="update_iframe">
</iframe>
</div>

The script that takes the content from the form and updates the
database is called update_db.cfm.

So, my function looks like:

function sub_this()
{
var mycgi = "update_db.cfm";
document.getElementById('update_iframe').src=mycgi ;
document.updfrm.target = document.frames['update_iframe'];
document.updfrm.submit();
}

My browser IE6 does not like this at all. Its dieing and barfing.

Anyone see any problems here.

I have gotten this to work using get, but not post. Using get my
sub_this function would look like:

function sub_this()
{
var mycgi = "update_db.cfm?thecontent=" +
document.updfrm.elements['myfield'].value;
document.getElementById('update_iframe').src=mycgi ;
}

I don't really want to use get because I'd have to encode every
variable in the url. Some of them may be long.

If the page with your form is already in the iframe, there is no need
to do a target. Just let the form submit and let it post back to the
same page.

Its not in the iframe ..... I plan on using the iframe for many things.
