window.top.opener.frames[0].Xrm.Page.getAttribute("fieldname").getValue() is not working in Microsoft edge

Hello Victoria,

Looking at your code, it is not supported, the reason behind is the fact that it uses DOM elementrs.

Here is the documentation behind:

https://docs.microsoft.com/en-us/dynamics365/customerengagement/on-premises/developer/use-javascript#write-javascript-for-multiple-browsers

Because you don’t know what browser will be in use, you should make sure that any scripts that you use will work with all supported browsers. Most of the significant differences between Internet Explorer and other browser have to do with HTML and XML DOM manipulation. Because HTML DOM manipulation is not supported, if script logic is only performing supported actions and using the Client API, the changes required to support other browsers could be small.

A cross-browser library like jQuery is a good solution for developing web resources but should not be necessary for form scripts or ribbon commands. More information: Avoid using jQuery for form scripts

The document above is applicable for both online and on premises environments.

https://docs.microsoft.com/en-us/dynamics365/customerengagement/on-premises/developer/supported-extensions

Also we have the document above where you can find this part:

"Directly accessing the Document Object Model (DOM) of any Dynamics 365 Customer Engagement (on-premises) application pages is not supported. The use of jQuery in form scripts and commands is not recommended. More information: Client scripting in Customer Engagement (on-premises) using JavaScript"

Both documents apply for online organizations as well.

Here's the document confirming the window.top is part of the DOM:

https://msdn.microsoft.com/en-us/ie/hh772148(v=vs.94)

https://msdn.microsoft.com/en-us/ie/hh772384(v=vs.94)

Inside the document above you will find the window object having the following description:

window

Represents an open window.

Other than this, looking at the code, Xrm.Page is deprecated since about 2 years ago:

https://docs.microsoft.com/en-us/power-platform/important-changes-coming#some-client-apis-are-deprecated

My recommendation is to use formContext.getAttribute(arg).getValue(); based on the document below and to skip the entire set of DOM elements in the beginning of the request:

https://docs.microsoft.com/en-us/powerapps/developer/model-driven-apps/clientapi/reference/attributes/getvalue#syntax

I hope this helps.
