SharePoint 2013 compatibility issue on IE11

Question

I have setup the SharePoint site to open in an iframe within a CRM portal.

When I try to upload a document and fill out the metadata, it gives an error that

'Field can't be blank' even though I have filled it out. 

It only happens in iframe-IE11. It works fine in IE10/chrome/Mozilla. It works fine if I open the SharePoint site directly in IE11 browser (outside iFrame).

How do I fix it in iframe-IE11?

Answer 1

The below code worked for me:

if (typeof browseris !== 'undefined') {
    browseris.ie = false;
}

The problem is in SharePoint 2013’s init.js file. The script calls attachEvent if it detects the browser to be IE.

I used the above code to override the property so browseris.ie never evaluates to true and attachEvent is never called. Find the original post here
