Question

你能帮我解决这个问题。我在Linux中使用Mozilla Firefox。当我关闭窗口或重新加载页面时，onload事件不起作用

<html>
  <head>

    <title>onunload test</title>

    <script type="text/javascript">
     window.onunload = unloadPage;

      function unloadPage()
      {
        alert("unload event detected!");
      }
  </script>
 </head>

 <body>
     <p>Reload a new page into the browser<br />
     to fire the unload event for this page.</p>
     <p>You can also use the back or forward buttons<br />
     to load a new page and fire this event.</p>
</body>

Answer 1

试试这段代码：

window.onbeforeunload = function(){
      return 'Are you sure you want to leave?'; // or anything you want to do
      };

Answer 2

尝试使用jQuery库，因为我认为jquery会考虑不同类型的浏览器：）

$( window ).unload(function() {
    alert( "unload event detected!" );
});

JAVASCRIPT的onunload事件在Linux Firefox中不起作用
