Transfer javascript code from iFrame to a DIV

[sameergn]

Hi,

I have HTML form whose target is an invisible IFrame. After the IFrame
is loaded completely,
following code transfers contents of IFrame to DIV

document.getEle mentById("mainD iv").innerHTM L =
test_iframe.doc ument.body.inne rHTML;

but this does not seem to carry over the Javascript code from IFrame to
DIV.
Can anyone comment if this is the correct behavior or a bug?
(The requirement is to submit a form and update only portion of screen,
without using
AJAX. A DIV cannot be target of the FORM, hence the IFrame->DIV route)

Thanks,
Sameer

`innerHTML' is a proprietary feature, so everything regarding it can be
considered correct behavior, even bugs.

This is utter nonsense. Simply make the IFrame visible in the first
place, and use CSS to style it.

Is the javascript inside the body of the IFRAME? To copy the contents
completely as they are, I would use
var content = test_iframe.doc ument.body.clon eNode( true );
document.getEle mentById("mainD iv").appendChil d( content );

But 'content' will be a body element, putting a body element inside a
div may have serious implications. You should probably loop through the
child nodes of 'content' and add them to the div one by one:
var content = test_iframe.doc ument.body.clon eNode( true );
var div = document.getEle mentById("mainD iv");

while (content.firstC hild) {
div.appendChild (content.firstC hild);
}

Thanks all of you for your replies.
Our architect suggested a simple solution. We added following code in
the JSP that loads in the IFrame

<script language="javas cript">
AddUserControll er = function() {
this.validate = function(formOb j) {
// validation code
}
}
window.parent.d ocument.addUser Controller = new AddUserControll er()
;
</script>

This add a Javascript object called addUserControll er in the parent
document and then
The code loaded in IFrame can use addUserControll er to call functions
like validate().

<script language="javas cript">
window.parent.g etIFrameData();
</script>

getIFrameData() is defined in parent document.
function getIFrameData()
{
document.getEle mentById("mainD iv").innerHTM L =
test_iframe.doc ument.body.inne rHTML;
} // getIFrameData() .

We initially were using DWR, but it allows accessing only POJOs
through AJAX and
we wanted to call just the JSP. We found that DWR uses same IFrame
mechanism
if posting method is IFrame instead of XMLHttpRequest (but still posts
to POJO).
Is there any recommended,wel l tested AJAX library that can be used
here to post to
any URLs?
