如何访问子窗口内的父窗口javascript变量（弹出窗口）？
问题描述：
我的html页面有全局javascript变量，名称 custName =scott。我用 window.open 打开弹出窗口。
I have html page which has global javascript variable with name custName="scott". I open the pop-up window with window.open.
现在如果我访问 custName 在弹出窗口中，带有 window.opener.custName ，我得到的值为 undefined 。如何在子窗口（弹出窗口）中访问父窗口javascript变量？
Now if I access the custName inside pop-up window with window.opener.custName, I get values as undefined. How do I access parent window javascript variable inside child window(pop-up)?
答
窗口。 opener.custName 有效。这是错误的错误。
window.opener.custName works. It was typo mistake.
