In JS, window. opener only references the parent window of the pop-up window. For example:
A.html, click "click" and click "other" to open a new window B .html. Contents.
If this reference fails, null is returned. Therefore, before calling an opener object, you must first determine whether the object is null. Otherwise, a JS error "the object is empty or does not exist" will occur.
