上发表servercontrolcrerateAJAX回_未分类的问答_编程通用

我怎么能回servercontrol crerate一个Ajax后？我觉得这个代码创建ClientControl.I AJAX回发想使用服务器控制按钮，而不是客户"LookUpButton"的控制？


<head id="Head1"  runat="server">

  <title>Client Callback Example</title>

  <script type="text/ecmascript">

      function LookUpStock() {

          var lb = document.getElementById("ListBox1");

          try 

          {

            var product = lb.options[lb.selectedIndex].text;

            CallServer(product, "");

          }

          catch(err)

          {

            alert("Please select a product.");

          }

      }

 

      function ReceiveServerData(rValue) {

          document.getElementById("ResultsSpan").innerHTML = rValue;

 

      }

  </script>

</head>

<body>

  <form id="form1"  runat="server">

    <div>

      <asp:ListBox ID="ListBox1" Runat="server">

      <br />

      <br />

      <input type="button" value="Look Up Stock" id="LookUpButton"  枚nclick="LookUpStock()" />

      <br />

      <br />

      Items in stock: <span id="ResultsSpan"  runat="server">

      <br />

    </div>

  </form>

</body>
