How to pass a value in a .net label through Javascript

I am coding in c# and javascript and I have some problems with setting a value through a javascript .js file, in order to use it in the code behind.

This is the .js file code

$(document).ready(function() {


$('#example1').ratings(10).bind('ratingchanged', function(event, data) {
    $('#examplerating1').text(data.rating);
$('#lblRating').text(data.Rating);

  });

And this is the html page code.

 Your Rating: <span id="examplerating1">not set</span>
            <asp:Label ID="lblRating" runat="server" Text="Label"></asp:Label>

Now the span value is setted correctly if I not use the runat="server". Now in order to access the value in the code behind i tried to put it in a label. But the value is not setted in the label. How can I use the data.rating value in the code behind passing though the HTML page?

Thanks

Check the rest of your code. If you have the label inside another .NET control, such as a master page, the span ID generated by .NET isn't the same as the ID you assigned in the .aspx file. For example, if it is inside a Content control named ContentPlaceHolder1, the ID will be ctl00_ContentPlaceHolder1_lblRating. As Cybernate says above, the ID that is generated depends on the NamingContainer that the label is part of.

ASP.Net controls ID gets changed based on the NamingContainer.

Change your jQuery to as follows:

$(document).ready(function() {
   $('#example1').ratings(10).bind('ratingchanged', function(event, data) {
    $('#examplerating1').text(data.rating);
    //Notice the change in the selector here.
    $('[id$="_lblRating"').text(data.Rating);

  });
