Hi,

I have an iframe on the form which contains a label and I am trying to access that label value on form save through javascript onsave event.

Like this:

Xrm.Page.ui.controls.get('IFRAME_FileUpload').getObject().contentWindow.document.getElementById('StatusLabel').value;

But I am getting this error when I debug:

'Error: Permission denied to access property "document"

What does this error mean? I have the checkbox 'Unchecked' for 'cross scripting' iframe properties.

Thanks for any help.

HI roxanna

How are you authenticating user access to the Iframes Website?

Hi Roxanna,

Per msdn.microsoft.com/.../jj602964(v=crm.7).aspx , the Xrm.Page.ui.controls.get('IFRAME_FileUpload').getObject() method returns an iframe element, so you'll have the properties and methods available here: msdn.microsoft.com/.../ms535258(v=VS.85).aspx

contentWindow is documented, but instead of contentWindow.document try: contentDocument

Hope this helps! I'd appreciate if you'd mark this as Answering your question.

Thanks,

Aiden

EDIT: document isn't a valid property of the window property. Changing it to contentDocument should fix the issue. Per: https://msdn.microsoft.com/en-us/library/ms535873(v=vs.85).aspx#properties

I tried your suggestion:

Xrm.Page.ui.controls.get('IFRAME_FileUpload').getObject().contentDocument.getElementById('StatusLabel').value;

I am seeing this error now:

There was an error with this field's customized event.

Field: crmForm

Event: onsave

Error: undefined

Thanks.

Can you put some logging (or even alerts) around that statement and break it up to see what's actually coming back null, something like this:

var frame = Xrm.Page.ui.controls.get('IFRAME_FileUpload');

var frameObj = frame.getObject();

var theDoc = frameObj.contentDocument;

var label = theDoc.getElementById('StatusLabel');

var theValue = label.value;

This will help you narrow down which object is causing the error.

Thanks,

Aiden

This sounds like a cross domain scripting issue. If the Iframe is from a different domain to CRM then you'll not be able to access it due to the same domain access policy. See madskristensen.net/.../iframe-cross-domain-javascript-calls

Hope this answers your question

Thanks, Scott.

Yes, the iframe is in different domain to CRM. How else can I access values from iframe?

What are my other options. I definitely need some connection between the form and iframe.. Please suggest.

Okay.. I figured a way myself and instead of messing up with these cross browser scripting.. I've decided to capture the file details and create a record all through server side coding and it was smooth.

So as the file gets uploaded on 'upload' button click event, I am creating a record with all the uploaded file data. And its working for my requirement.

Thanks guys for suggestions.
