直接createElement一个新的折线代替掉原来的吧

解决方案 »

  1.   

    <v:polyline id="mypolyline"
       points="50,0 120,50 150,100 170,175 250,200">
       </v:polyline>
      

  2.   

    试试这个:<html xmlns:v="urn:schemas-microsoft-com:vml">
    <head>
    <title>testing VML</title>
    </head>
    <STYLE>
     v\:* { BEHAVIOR: url(#default#VML) }
    </STYLE>
    <body>
    <div>
    <v:polyline id="mypolyline1"    points="50,0 120,50 150,100 170,175 250,200">  </v:polyline>
    </div>
    <button onclick="test()">test</button>
    <SCRIPT LANGUAGE="JavaScript">
    <!--
    function test()
    {
    poly = document.createElement("<v:polyline id=\"mypolyline2\"    points=\"0,50 120,50 100,150 170,175 250,200\">  </v:polyline>");
    mypolyline1.parentNode.insertBefore(poly.cloneNode(),mypolyline1)
    mypolyline1.parentNode.removeChild(mypolyline1)
    }
    //-->
    </SCRIPT></body>
    </html>
      

  3.   

    一点说明:
    mypolyline1.parentNode.insertBefore(poly.cloneNode(),mypolyline1)
    先在mypolyline1前面插入以个新的polyline对象
    mypolyline1.parentNode.removeChild(mypolyline1)
    再把原来的polyline对象删掉。

    你给的代码不行阿,说缺少对象。
    另外,微软msdn上说用
    element.points="express"

    秋水就是秋水。
    function replace(){
     var arr=document.all("data");
     var str="";
     for(i=0;i<arr.length;i++)str+=(i*xMax/arr.length)+"pt,"+(yMax-arr[i].value)+"pt "
     polyline= document.createElement("v:polyline")
     polyline.points=str;
     doc.replaceChild(polyline,doc.children[1])
    }
    写的比我漂亮多了
