推荐答案

您需要获取关闭 [

You need to get the Window.Closing Event[^] which occurs directly after Close [^]is called, and can be handled to cancel window closure.

public event CancelEventHandler Closing

在这种情况下，您可以检查用户是否注销，如果没有注销，则取消窗口关闭和关闭.防止您的窗口关闭.

这是如何在ASP.Net(C#)中检测浏览器关闭事件的参考 [ ^ ]，您可能会从中获得一些帮助.

On this event you can check whether user is logged out or not, if not then cancel the window closure & prevent your window from closing.

Here is reference for How to detect the browser close event in ASP.Net (C#)[^] you may get some help from it.

使用onbeforeunload事件

Use onbeforeunload event

<script type="text/javascript"> 
window.onbeforeunload = function (evt) { 
  var message = 'Are you sure you want to leave?'; 
  if (typeof evt == 'undefined') { 
    evt = window.event; 
  } 
  if (evt) { 
    evt.returnValue = message; 
  } 
  return message; 
} 
</script>
