［原］JS动态创建VML

//画直线，加入到group1
function createLine(id,startArrow,endArrow){
      var le = document .createElement( "<v:line><v:line>" );
            var ske = document.createElement("<v:stroke/>");
            if(startArrow != '')
       ske.StartArrow="classic";
   if(endArrow != '')
       ske.EndArrow="classic";
   le.appendChild(ske);   
      le.id = id;
      group1.insertBefore(le);
     } 

//画圆角矩形，有3D效果，加入到group1
     function createRect(id,text,left,top,isEnd){
         var rectColor="#61f2fe";
         if(isEnd=='t')rectColor="red";
      var strElement='<v:roundrect fillcolor="'+rectColor+'" id='+id+' style="POSITION:absolute;Z-INDEX:1;left:'+left+';width:70;top:'+top+';height:70" strokecolor="black" strokeweight="1px" onmousedown="down(this)" onmousemove="move(this)" onmouseup="up(this)" title = "' + text + '"></v:roundrect>';
      var newRect = document.createElement(strElement);
   newRect.innerHTML = "<v:TextBox inset='5pt,5pt,5pt,5pt' style='font-size:10.2pt;'>"+text+"</v:TextBox>";
   var extru = document.createElement('<v:Extrusion></v:Extrusion>');
   extru.on="t";
   extru.foredepth="0";
   extru.backdepth="4pt";
   extru.color=rectColor;
   extru.rotationangle="0,0";
   newRect.appendChild(extru);
