MS Crm 2011 javascript Iframe functions

Question

I'm facing a problem with an IFrame on MS CRM 2011. I'm trying to generate HTML code and write it into an IFrame. I'm quite new to CRM development so I hope you could guide me to a solution.

After I generate the HTML content (IframeHTML) via JavaScript I try to write that content to an IFrame and then reload the whole Form. Everything is working fine until I reach my last command

var control = document.getElementById("IFRAME_name");
control.contentWindow.document.open();
control.contentWindow.document.write(IframeHTML);
control.contentWindow.document.close();
control.location.reload(true);

The script is executed on OnLoad of the Form, but it gives me an alert that

Access is denied

at the end.

If I replace the first line with :

var control = Xrm.Page.ui.controls.get("IFRAME_name");

it tells me

Document is not supported.

I'm not sure if I recognized what the problem here is so any help would be nice.

Yeah, you can't use Xrm.Page to get the IFRAME, so the first block of code you have looks good. I use very similar code in CRM 2011 (see below) and it works fine, so I'm assuming your error is due to something else. var iFrame = document.getElementById("IFRAME_name"); var doc = iFrame.contentDocument; if (doc == undefined || doc == null) { doc = iFrame.contentWindow.document; } doc.open(); doc.write(IframeHTML); doc.close(); — Peter Majeed
Actually, a difference may be in the control.location.reload(true) line. Do you need that line of code for any reason? — Peter Majeed

You have to activate Crossframe Scripting in the IFRAME properties.

Have you done that?

Regarding the Xrm.Page call, you can get the IFRAME using

var control = Xrm.Page.ui.controls.get("IFRAME_name").getObject();

This is the supported way to get the IFRAME, so you should use that.
