仅当窗口关闭时才能启动（包括工作示例） [英] Fire onbeforeunload only when window is closed (includes working example)

问题描述

只有当标签页或浏览器关闭，而不是刷新，链接点击等时，我只想启动onbeforeunload事件。我发现一个网站有效： https://checkout.deindeal.ch/

在Chrome中触发事件的步骤：

1. 将某物放入购物车


2. 点击Zur Kasse


3. 关闭标签


4. onbeforeunload显示消息并弹出一个弹出窗口。 onbeforeunload事件，如刷新不会触发。我调试了他们的代码，但找不到他们排除这些事件的地方。

任何人都可以在代码中找到正确的地方？

谢谢！

解决方案

对于想要使用 onbeforeunload 的读者， / p>

事件 onbeforeunload 应用于防止用户的数据丢失，如填写表单和其他数据，不保存，并将在刷新页面时丢失。

使用 onbeforeunload 来防止一个用户离开你的页面是令人讨厌的，并且不会阻止用户离开。

除非用户使用按键可以检测到的快捷方式（例如 Ctrl + F5，否则无法检测到 浏览器选项卡刷新按钮 ）。

Fire onbeforeunload确认e仅限外部站点

I want to fire the onbeforeunload event only when the tab or browser is closed and not upon refresh, link click and so on. I found a site where that works: https://checkout.deindeal.ch/

Steps to fire the event in Chrome:

1. Put something into the cart
2. Click on "Zur Kasse"
3. Close tab
4. onbeforeunload Message is shown and a popup opens. onbeforeunload events like refresh will not fire. I debugged their code, but could not find the place where they exclude those events or whatsoever.

Anyone out there who can find the correct place in the code?

Thanks!

解决方案

For readers that want to use onbeforeunload,

The event onbeforeunload should be used for preventing user's data loss, like filled in forms and other data that are not saved and will be lost upon page refresh.

Using onbeforeunload to prevent a user from leaving your page is annoying and will not stop the user from leaving.

You can not detect a browser tab refresh button press, unless the user use a shortcut that you can detect with key press (like Ctrl+F5). More info here : javascript beforeunload detect refresh versus close
