      {
        var waitDiv
        
        //判断div是否存在
        if (waitDiv=document.getElementById("waitDiv"))
        {
          //如果存在则直接显示
          waitDiv.style.display = "block";
        }
       else
        {
          //如果不存在则创建新的div
          waitDiv = document.createElement("div"); 
          waitDiv.id = "waitDiv";
          waitDiv.style.position = "absolute";
          waitDiv.style.width = "265px";
          waitDiv.style.height = "75px";
          waitDiv.style.left = "35%";
          waitDiv.style.top = "30%";
          waitDiv.style.background = "#eee";
          waitDiv.style.border = "1px solid #3b4058"

          waitDiv.style.zIndex = "10001";
          }
        
        //提示框信息
        var hintMsg = " 正在处理中...";
        
        if (typeof(message)!="undefined")
        {
           hintMsg = message;
        }
        
        waitDiv.innerHTML = "<img src='../image/progress.gif'>   正在处理中...";
        
        //创建遮罩层，不允许点击后面的元素
        //获取当前的页面高、宽
        var sWidth,sHeight;
        sWidth=document.body.scrollWidth;
        sHeight=document.body.scrollHeight;
        //创建遮罩div
        var bgDiv=document.createElement("div");        bgDiv.id="bgDiv";
        bgDiv.style.position="absolute";
        bgDiv.style.top="0";
        bgDiv.style.left="0";
        bgDiv.style.background="#F5FBFE";
        bgDiv.style.filter="progid:DXImageTransform.Microsoft.Alpha(style=3,opacity=25,finishOpacity=75";
        bgDiv.style.opacity="0.6";
        bgDiv.style.width=sWidth;
        bgDiv.style.height=sHeight;
        bgDiv.style.zIndex = "10000";
        
        //将创建的遮罩层和提示信息添加到Body
        document.body.appendChild(bgDiv);
        document.body.appendChild(waitDiv);
        //不允许右键
        document.body.onselectstart = function(){return false;}
        document.body.oncontextmenu = function(){return false;}
      }
      
      //隐藏遮罩层和提示框
      function hideWait()
      {
        var bgDiv = document.getElementById("bgDiv");
        var waitDiv = document.getElementById("waitDiv");
        
        if (bgDiv!=null && bgDiv != "undefined" )
        {
          document.body.removeChild(bgDiv);
        }
        if (waitDiv!=null && waitDiv != "undefined" )
        {
          document.body.removeChild(waitDiv);
        }
      }
      
      hideWait();遮罩在IE6的环境下还等选中被遮罩的下拉菜单 拜托各位解答。如果贴上解决方案最好 小女子感谢大家了
