ASP.NET 根据TextBox输入的内容自动自动定位到ListBox中项

            这个效果很简单，直接上代码
[javascript]
<script type="text/javascript"> 
 
       function OnTextChanged(textBoxID, listBoxID) { 
           var inputText = $.trim($("#" + textBoxID.toString()).val()); 
           if (inputText.length != 0) { 
               for (var i = 0; i < document.getElementById(listBoxID.toString()).options.length; i++) { 
                   document.getElementById(listBoxID).options[i].selected = false; 
               } 
 
               var sInputName = inputText.toUpperCase(); 
               var iStopFlag = -1; 
               var iIndex = 0; 
               var sText; 
               while (iIndex < document.getElementById(listBoxID).options.length && iStopFlag == -1) { 
                   sText = document.getElementById(listBoxID).options[iIndex].text.toUpperCase(); 
                   if (sText.indexOf(sInputName) != -1) { 
                       document.getElementById(listBoxID).options[iIndex].selected = true; 
                       //iStopFlag = 0; 
                   } 
                   iIndex++; 
               } 
           } 
       } 
       
   </script> 

前台代码：
[html] 
<table> 
 <tr> 
            <td> 
                <div style="margin-top: 0; text-align: right"> 
                    定位商户(请输入商户名称)： 
                    <asp:TextBox ID="txtLocateAllSeller" runat="server" onkeyup="OnTextChanged('txtLocateAllSeller','liboxAllSellers')"></asp:TextBox></div> 
            </td> 
            <td> 
            </td> 
            <td> 
                <div style="margin-top: 0; text-align: left"> 
                    定位商户(请输入商户名称)： 
                    <asp:TextBox ID="txtLocateSelectSeller" runat="server" onkeyup="OnTextChanged('txtLocateSelectSeller','selectSellers')"></asp:TextBox></div> 
            </td> 
        </tr> 
</table> 
这个js方法好处就是一个通用方法，只需要传入TextBox的ID和ListBox的ID即可。定位也相当于模糊查询。
