I can't get the bit of JavaScript code. Was watching a tutorial on JavaScript so I tested it my self. I went to read up a bit and some sources said it did not work in Chrome so I tested with Firefox. However, it still did not work on Firefox. What went wrong?
<body onUnload="alert('Good Bye!');"></body>
UPDATE: By the way, the person in the tutorial used
<body onUnload="alert('Good bye');"></body>
and it worked for him. He was using a older version of Chrome.
除非您要定位较旧的浏览器,否则请尝试OnBeforeUnload。
