问题描述
如何在切换标签时不允许取消Alert Box。
使用 alert（测试） ）; 在谷歌浏览器上，当您切换标签时，警报对话框消失，当您返回同一标签时，您可以完全访问。
Using alert("Test"); on Google Chrome, when you switch tabs, the alert dialog box disappears, and when you're back on the same tab you have full access.
当你创建一个问题并尝试关闭标签时，我想要的是做与 stackoverflow 网站相同的事情，弹出一个不允许你去的对话框任何地方，直到你选择（离开或保持）。
What I want is to do the same thing as stackoverflow website when you create a question and try to close the tab, there's a dialog box that pops up that doesn't allow you to go anywhere until you choose between (Leave or Stay).
IE和Firefox的工作方式不同，我的意思是阻止使用提醒（测试）; 语句时的标签，但谷歌浏览器不会阻止。
IE and Firefox work differently, I mean block the tab when using alert("Test"); statement but Google Chrome doesn't block.
我发了一个错误报告给谷歌，但他们回复我：
这是按预期工作，请参阅。
这不是安全漏洞;用户可以使用开发人员工具或无数其他技巧使对话框消失。
I sent a bug report to Google but they replied to me that :This is working as intended, see Issue 629964.It's not a security bug; a user could make the dialog box disappear with developer tools or myriad other tricks as well.
