     var sWidth,sHeight;
     sWidth=document.body.offsetWidth;
     sHeight=screen.height;
     var bgObj=document.createElement("div");
     bgObj.setAttribute('id','bgDiv');
     bgObj.style.position="absolute";
     bgObj.style.top="0";
     bgObj.style.background="#777";
     bgObj.style.filter="progid:DXImageTransform.Microsoft.Alpha(style=3,opacity=25,finishOpacity=75";
     bgObj.style.opacity="0.6";
     bgObj.style.left="0";
     bgObj.style.width=sWidth + "px";
     bgObj.style.height=sHeight + "px";
     bgObj.style.zIndex = "10000";
     document.body.appendChild(bgObj);
     var msgObj=document.createElement("div")

     msgObj.setAttribute("align","center");
     msgObj.style.background="white";
     msgObj.style.border="1px solid " + bordercolor;

       msgObj.style.top = "20%";
       msgObj.style.font="12px/1.6em Verdana, Geneva, Arial, Helvetica, sans-serif";
       msgObj.style.marginLeft = "-525px" ;
       msgObj.style.marginTop = -75+document.documentElement.scrollTop+"px";
       msgObj.style.width = msgw + "px";
       msgObj.style.height =msgh + "px";
       msgObj.style.textAlign = "center";
       msgObj.style.lineHeight ="25px";
       msgObj.style.zIndex = "10001";
      var title=document.createElement("h4");
      title.setAttribute("id","msgTitle");
      title.setAttribute("align","right");
      title.style.margin="0";
      title.style.padding="3px";
      title.style.background=bordercolor;
      title.style.filter="progid:DXImageTransform.Microsoft.Alpha(startX=20, startY=20, finishX=100, finishY=100,style=1,opacity=75,finishOpacity=100);";
      title.style.opacity="0.75";
      title.style.border="1px solid " + bordercolor;
      title.style.height="18px";
      title.style.font="12px Verdana, Geneva, Arial, Helvetica, sans-serif";
      title.style.color="white";
      title.style.cursor="pointer";
      title.innerHTML="关闭";
      title.onclick=function(){
      document.body.removeChild(bgObj);
       document.getElementById("msgDiv").removeChild(title);
       document.body.removeChild(msgObj);
       }
      document.body.appendChild(msgObj);
      document.getElementById("msgDiv").appendChild(title);
      var txt=document.createElement("p");
      txt.style.margin="1em 0"
      txt.setAttribute("id","msgTxt");
      txt.innerHTML=str;
      document.getElementById("msgDiv").appendChild(txt);
      }
    function ajax_form(url)
    {
     $.post(url,
     {Action:"POST"},
     function (data)
     {
      sAlert(data);
     }, 
     "html");
