~~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:

XML

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

2:

XML

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

3:

XML

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

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

C#

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;

"Not working" is not informative. What did you want to do whith valBusType? Did you check its value under debugger? In this like of code even ever executed? If in doubt, use the debugger or provide debug output into the HTML page being generated in HTTP response.

Solution 1

It should work, if this is a valid control with valid id. You did not show what you do with valBusTypel and that can also be a problem. The functions returns JavaScript DOM innerHTML property. Please see:
http://api.jquery.com/id-selector/[^],
http://api.jquery.com/html/[^],

Please also see my comment to the question.

Solution 2

Try value instead of html:
JavaScript

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

Here:

JavaScript

var valBusType =$('#Label2_fromTo').val();

I think it should be .val(), not .value as it is jquery.

:doh: Thanks Marcus.

Updated. Actually, selector too could be simplified.

Did not get your selector though. '#' requires id...

Yep. Based on what OP was trying, ID shouls be : Label2_fromTo (Based on this line: Label2_fromTo.ClientID)
