使用jquery的textbox onchange事件导致JScript运行时错误：’Deductions’未定义

我有一个关于为textBox onchange事件调用jQuery的查询.

在我的编码我呼吁onchange事件为

<asp:TextBox ID="txtTotalDeductions"  Text="0" runat="server" 
                                                        ClientIDMode="Static"     onChange="Deductions();" ></asp:TextBox>

我有两个div部分

<div id="Total">1000</div>

和

<div id="NetTotal">0</div>

我需要通过减去Total – txtTotalDeductions来计算“NetTotal”.

而我的jQuery for Deductions是

//计算扣减额.

function Deductions() {


      var result = new Object();

      result.total = $("#Total").html();
      result.totalDeductions = $("#txtTotalDeductions").val();

      result.netTotal = result.total - result.totalDeductions;
      $('#NetTotal').html(result.netTotal);
  }

当我运行应用程序时,错误显示为“Microsoft JScript运行时错误：’扣除’未定义”,错误在于“”

任何人都可以帮助我…请提前谢谢

解决方法

删除OnChange处理程序

function Deductions() {


      var result = new Object();

      result.total = $("#Total").html();
      result.totalDeductions = $("#txtTotalDeductions").val();

      result.netTotal = result.total - result.totalDeductions;
      $('#NetTotal').html(result.netTotal);
  }

还将代码包装在ready处理程序中并附加change事件处理程序

$(document).ready(function(){
 //attach with the id od deductions
$("#txtTotalDeductions").bind("change",Deductions);

});
