Window to window Communication in js by window name

Question

Is there anyone who can give me some thoughts on how to handle window-to-window communication using javascript givin, that the two windows do not have parent child relations. Basically, another window is opened using the window.open method. Any brilliant information is well appreciated.

Answer 1

assuming the following:

windowHandle=window.open('path/to/document');

You can interact between both windows.

You have a pointer to a window object from the document in which it was opened using the variable name:

//doSomething has to be known inside the new window
windowHandle.doSomething();

and from the document in a new window to a window opening a new window using opener-property:

//doSomething has to be known inside the window that opened the new window
opener.doSomething();
