用js操纵过vml的请帮忙,如何读写v:PolyLine的points?
直接用obj.points和用getAttribute、setAttribute都试过。。。   
 试验代码如下     
  <html   xmlns:v= "urn:schemas-microsoft-com:vml ">  
  <head>  
  <meta   http-equiv= "Content-Type "   content= "text/html;   charset=gb2312 "   />  
  <title> 无标题文档 </title>  
  <STYLE>  
 v\:*   {   Behavior:   url(#default#VML)   }   
  </STYLE>  
  <script>  
 function   aa(){ 
 	var   obj=document.getElementById( "pc1-print2 "); 
 	alert(obj.getAttribute( "points ")); 
 	alert(obj.points); 
 	obj.setAttribute( "points ", "100,100   200,250   300,400   500,800 ",0); 
 //	obj.points= "100,100   200,250   300,400   500,800 "; 
 } 
  </script>  
  </head>    
  <body>  
  <v:PolyLine   id= "pc1-print2 "   filled= "false "   points= "630,330   630,530   480,530 "   strokeweight= "1 "   style= "position:absolute;z-index:10; "   strokeColor= "blue "   fillcolor= "blue ">  <v:TextBox   inset= "102px,200px,0px,0px "   style= "font-size:12px; "> 曲线 </v:TextBox>  <v:stroke   EndArrow= "Classic "/>  </v:PolyLine>  
  <input   type= "button "   name= "Submit "   value= "读写 "   onclick= "aa(); "/>  
  </body>  
  </html>
