问题描述

下面的代码不起作用:

谢谢大家的答复.在这里，我正在改善我的问题，以便可以更容易理解和回答.

我的default.aspx页(在.net 3.5中)具有这些控件.

Below code is not working:

var valBusType =$(''#%=Label2_fromTo.ClientID %>'').html();

Thank you all, for your reply. Here I am improving my question so that it can be more understandable and answerable.

I have these controls on my default.aspx page (in .net 3.5)
1:

<asp:DropDownList ID="DdlPickUpPoint" runat="server" CssClass="select" Width="300"></asp:DropDownList>

2:

2:

<asp:TextBox ID="txtSeatNo" runat="server" CssClass="hideBorder" onKeyPress="return false"></asp:TextBox>

3:

3:

<asp:Label ID="lblTotAmt" runat="server"  ></asp:Label>

现在，我想使用jquery在JScript.js中获取这些控件的值，然后将其传递给webservice.代码在下面

Now I want to get values of these controls in JScript.js using jquery and then pass it to webservice . Code is below

var valTotValue= =$('#<%=lblTotAmt.ClientID %>').val();
var valSeatNo= =$('#<%=txtSeatNo.ClientID %>').val();
var valPickupPoint =$('#<%=DdlPickUpPoint.ClientID %>').html();
debugger;
$.ajax(
{
 type: "POST",
 url: "WebService_SeatLayout.asmx/GetLayout
 data:"{'strTotValue' : " + valTotValue + ",'strSeatNo': "+ valSeatNo + ",'valSeatNo' : " + valPickupPoint + "}",

contentType: "application/json; charset=utf-8",
dataType: "json",
async: true,
cache: false,
success: function (msg)
{

alert(msg.d);
if(msg.d==true)
{
 var url = 'CustInfo.aspx';
 window.location.href = url;
 }

           },
           error: function (x, e)
           {
           alert("The call to the server side failed. " + x.responseText);
           }
       }
   );
   return false;

(``#％= Label2_fromTo.ClientID％>'')).html();
