If i have an iframe that has the following structure
<iframe id="iframesitefileupload" src="IframeTest.aspx" style="margin-left:20px" name="iframesitefileupload">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<body>
<form id="form1" action="IframeTest.aspx" method="post" name="form1">
//add stuff here ----
</form>
</body>
</html>
</iframe>
How can i append contents to the form element?
