在集智平台上绑定右键菜单：
<SCRIPT language=JavaScript1.2>
//如果当前浏览器是Internet Explorer，document.all就返回真
//选择菜单方块的显示样式
//ie5menu=document.getElementById(“ie5menu”);
ie5menu.className = menuskin;
//重定向鼠标右键事件的处理过程为自定义程序showmenuie5
document.getElementById(“report1“).oncontextmenu = showmenuie5;
//重定向鼠标左键事件的处理过程为自定义程序hidemenuie5
document.body.onclick = hidemenuie5;
