问题描述

我有一个打开多个窗口的Web应用程序。我遇到的问题是,当父窗口关闭/刷新时,子窗口仍然打开。
我尝试过使用 onunload onbeforeunload 但是没有人抓住窗口关闭事件(在Chrome中)和Firefox)。
我有一个窗口数组但刷新后对它们的引用会丢失。

I have a web application that opens multiple windows. The problem that I have is that when the parent window is closed/refreshed, the child windows remain opened. I've tried using onunload and onbeforeunload but none of them catches the window close event (in Chrome and Firefox). I have an array of windows but after refresh the reference to them is lost.

还有其他方法可以捕获此事件吗?

Is there any other way to catch this event?

这是我关闭窗口的代码(在卸载 closeAll() >和 onbeforeunload 关闭我打开的所有窗口,但不刷新页面时:)

This is my code related to closing windows (running closeAll() outside unload and onbeforeunload closes all my opened window, but not when the page is refreshed):

window.unload = function() {
   closeAll();
}
window.onbeforeunload  = function() {
   closeAll();
}

var closePopup = function(popup) {
   removePopup(popup);
   popup.close();
};

var closeAll = function() {
   for (var popup in _this.popups) {
       closePopup(_this.popups[popup]);
    }
}

这仅适用于Chrome,但不适用于Firefox和IE (最新版本)。

This works only in Chrome but not in Firefox and IE (latest versions).

推荐答案

找到适用于最新版Chrome,Firefox和IE的正确解决方案(jQuery)。

Found a proper solution (jQuery) that works in the lastest versions of Chrome, Firefox and IE.

最初想要使用jQuery $()。unload() function( http://api.jquery.com/unload/ )但它自1.8以来已被弃用( http://bugs.jquery.com/ticket/11733 )。由于 $()。unload() $()的快捷方式.bind('unload',fn) ,我试图使用基本的,它的工作原理。

Initially wanted to use jQuery $().unload() function (http://api.jquery.com/unload/) but it's deprecated since 1.8 (http://bugs.jquery.com/ticket/11733). Since $().unload() is the shortcut for $().bind('unload', fn), I tried to use the basic one and it worked.

$(window).on('unload', function() {
    closeAll();
});
