Issue passing variable from javascript to c#

Question

I am trying to pass the value of a variable from javascript to C#.

Here is the client side part:

  <input type="text" value="1" id="h" name="n" runat="server" />
  <script>
    $("a").on("tap", function (event) {
    var a = event.target.id;
    $("#h").val(a);
    });
  </script>          

and the server side part:

<%
string param = h.Value;
Response.Write(param);
            %>

The input field has an initial value=1. A JQuery event changes the value attribute to, let's say, 5. When I try to access the value of input from server side (h.Value), the value is again, 1.

What am I doing wrong?

Thank you.

我相信你需要使用ASP.NET TextBox控件而不是普通的html input 。
