Internet explorer 11 javascript : Object are static

Question

Using the interactive console in IE11 (F12), I have static object

user=> a={a:5,b:6} [object Object] { a : 5 , b : 6 } user=> a.l=6 object does not support this property

The first line of the Console says :

The attached page targets document mode 5. Some console APIs and features may not be available.

Yes, indeed, some API are not accessible!

How can I get dynamic object with javascript in IE11?

I just checked in IE11 and that code works fine, though I'm not sure what this user=> part is supposed to be, I just did the a= part which assigns a to window — nanobar

Please provide the conditions it doesn't work in, not sure what you mean by what type of document — nanobar

Here I edit, I found a "attached document is in mode 5. Some API could not be accessible." — MUY Belgium

You've set your document mode to 5 (Internet Explorer 5), change it back to 11:

In my case, the document was a document in a frame windows.

So, I added the following line in the headerof the html document that countains the frameset tag.

<meta http-equiv="X-UA-Compatible" content="IE=10" />

Then the message did not appears again. It seems that the problem was solved and that attribute can be added dynamically as in the w3c norm.
