javascript 判断是页面关闭还是页面刷新

最近在做一个权限控制的项目,想让一个用户打开一个报表以后其他用户就不用在重新打开,我在打开的时候创建了一个临时表,然后象临时表里面添加、删除记录,所以在用户关闭页面的时候要删除记录,但是用户的离开方式多种多样,怎么在用户非法离开的时候既时的判断离开呢?最常见的非法离开就是关闭浏览器了。  
<script type="text/javascript" language="javascript">
            function closeWinform()
            
{
                
if(window.event.clientX>document.body.clientWidth&& window.event.clientY<0 || window.event.altKey)
                
{
                    document.all(
"Button1").click();
                }

            }

        
</script>
BODY   的   UNLOAD和onbeforeunload事件会在浏览器清除所加载的信息时被触发,也就是说页面在回送、重定向或被关闭的时候就会触发 Button1的点击事件,然后执行删除程序,但是现在对于特殊的浏览器,象遨游、ie7可以打开多个窗口的那种,通过这种获取用户鼠标位置的方法就有点问题了。他们获取的鼠标的坐标值就有可能小于客户窗体的宽度,所有window.event.clientX>document.body.clientWidth这个条件可以不要。
