Summary
Returns a reference to the window that opened this current window.
Syntax
objRef = window.opener;
Example
if (window.opener != indexWin) { referToTop(window.opener); }
Notes
When a window is opened from another window (using Window.open
), it maintains a reference to that first window as window.opener. If the current window has no opener, this method returns NULL.
Windows Phone browser does not support window.opener (tested with Microsoft Edge 25.10586.36.0). It is also not supported in IE if the opener is in a different security zone.
