推荐答案

您不能直接被通知窗口关闭，但你可以计算出，当子窗口已通过检查的 关闭 通过的 window.open（）

You can't directly be notified of the window closing, but you can work out when the child window has been closed by inspecting the closed property on the window object reference returned by window.open().

下面是通过轮询被关闭，这将显示子窗口的5秒内警报的例子关闭属性：

Here's an example that will display an alert within 5 seconds of the child window being closed by polling the closed property:

var win = open('http://www.google.com');
var intervalId = setInterval(function() {
        if (win.closed) {
            clearInterval(intervalId);
            alert('Window closed! Hoorah!');
        }
    }, 5000);
