which I can access and process the variable(string) in parent window?

such as from popup page, we have var_from_popup="abc", after the popup
closed, then from parent window, we can use alert(var_from_popup) and

推荐答案

使用window.opener来引用父项，然后你可以在父窗口中设置你想要的任何变量。

Use window.opener to refer to the parent, then you can set whatever variable you wish in the parent window.

主窗口中有一个变量var varwindow;

弹出的
，我设置

window.opener。 varwindow =" abc"


然后从主窗口，我使用alert（varwindow）但

它写为underfinded"但不是abc..为什么？

there is a variable var varwindow in primary window;

from popup, i set
window.opener.varwindow="abc"

then from primary window , i use alert(varwindow) but
it write as "underfinded" but not "abc"..why?
