Question

if the title is not clear
let me describe it again
if has a page a.html that has a javascript code below

    window.open("http://www.baidu.com/", "_self", "");

and how can the original window and the new opened window communicate??

thanks

Answer 1

The new document will have an opener property that references the window from which it was opened. This will be lost if the browser is navigated to a new document.

The return value of open will be a reference to the new window (so you’ll need to assign it to a variable).

The same origin policy applies as usual.
