Is there a way to differentiate between elements with the same ID but in different browser tabs?

Question

Let's say I have my website open in two tabs, and i want to get the element with the id "id", can I somehow get the element in the currently focused browser tab?

document.getElementById("id"); 

seems to get the element that was loaded most recently.

No, since that would be a gaping security hole.

There's a similar question on stackoverflow: Accessing the content of other tabs in browser .

This answer to the linked question provides code to do it, but I had problems in the past with IE, when trying to specify event handlers on the other document (worked fine in Firefox though).
