获取参考现有的浏览器窗口 [英] Obtain reference to existing browser window

问题描述

我99％肯定的回答我的问题就没有，但以防万一...

I'm 99% sure that the answer to my question will be no but just in case...

使用情况：

1. 网页中打开使用JavaScript（同一域）
一个新的窗口b。

2. 用户刷新A或导航离开，然后返回


3. 在网页A链接用户点击它应该关闭B

1. Webpage A opens a new window B with JavaScript (same domain)
2. The user refreshes A or navigates away and then returns
3. The user clicks on a link in page A which should close B

这通过，只要用户不刷新，从A（步骤2）导航客场持有窗口参考工作正常。

This works fine by holding on to the window reference as long as the user does not refresh and navigates away from A (step 2).

是否有任何（外来与否）的方式返回到何时重新获得pviously打开的窗口中（S）引用了$ P $？

Is there any (exotic or not) way to re-obtain the reference to the previously opened window(s) when returning to A?

推荐答案

是

function openWin() {
  w = window.open("","windowname"); // use the window name you gave it when you opened it
  if (w && !w.closed) ...
}
