关闭不带window.open（）的窗口；

Question

Is there any way to close a new tab window that was not opened using window.open(); ?

Answer 1

否。如果您没有打开窗口，则不要关闭它。

Answer 2

Please see here: http://www.infimum.dk/HTML/JSwindows.html#ref_3_11

In order to close a specific window using the window.close() method you need a reference to that window, which you can usually get when opening a window using the window.open() method.

Another option I can see is to use global window/frame references (self, parent, opener, etc...You can see the list in the link above as well).
