js捕捉状态栏的鼠标右键关闭

Question

原因是：用户单击浏览器右上角的关闭按钮，我会给用户一个提示"您已关闭了浏览器'"，但用户问我那我如果单击的是状态栏的鼠标右键并且是关闭，那能实现同样效果吗？我无语了

<script>
 function closeBrowse()
  {
 　　alert('您已关闭了浏览器');  
  }
 window.onload = closeBrowse
</script>

请大虾指教，不甚感激

Answer 1

<Script Language="JavaScript">function window.onunload(){&nbsp; //when close ie&nbsp; if(window.screenLeft==10004)&nbsp;&nbsp; {&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;alert("您已关闭了浏览器'");&nbsp;&nbsp;&nbsp;}&nbsp;}</Script>这个在ie6下没问题，其他的还没测过。&nbsp;在globa.asax里实现session end事件应该也可以
