Accessing another windows variables

[User 4300686]

I have define a variable in window A. I set it to parent.variable=xxxx Now I open a new tab (window B). Can I access or take the parent.variable from window A in window B ?

Only if window B can refer to something in A's tree. I think when A spawns B it gets a reference to the new window, so A can add a reference to its own window into B's (i.e. new_window.referenceToA = window), and then code in B can use window.referenceToA.xxx.

If you opened the new window from the original window, you should be able to access the

window.opener

property in the DOM of the new window. This property gives you access to the DOM of the original window. Here is a link to the MDN entry for this property click[^] Cheers!
