我如何处理页面上的 "refresh" 事件?

How can i handle "refresh" event on my page?

我想在用户单击 "refresh" 后显示一个确认弹出窗口 "Do you want to refresh this page"。如果用户在弹出窗口中选择是,则页面应刷新,否则应保持原样。

谢谢

您可以使用此 javascript 代码来检查页面刷新。

window.onbeforeunload = function(){
return "Do you want to refresh this page";
};

我这样做了并且成功了

  window.onbeforeunload = 
     function(){
       return "Refreshing page will result in loss of data, do you want to continue ?";
     };
