父窗口如何知道其子窗口已关闭? [英] How Can a parent window know that its child window closed?

问题描述

我想在打开的子窗口关闭时执行功能.子窗口的打开代码为:

I want to execute a function when an opened child window is closed. Child window opening code is:

outWin = window.open (pageURL, title, 'toolbar=no, location=no, directories=no, status=no, menubar=no, scrollbars=yes, resizable=no, copyhistory=no, width=600, height=400, top=100, left=100);

我想调用在父窗口中编写的Javascript函数.我正在使用YUI-2开发插件.我该如何运作?应该注册什么事件?

I want to call a Javascript function written in parent window. I am using YUI-2 for developing the plugin. How can I make it work? What event should be registered?

推荐答案

您可以执行以下操作.

var intervalID, childWindow;

childWindow = window.open("http://www.google.com");

function checkWindow() {
    if (childWindow && childWindow.closed) {
        window.clearInterval(intervalID);
        alert('closed');
    }
}
var intervalID = window.setInterval(checkWindow, 500);
