I find it..To take a value from Javascript to your local Database at Visual Studio with ASP you have to add at
.aspx
<asp:HiddenField runat="server" ID="hfProduct" ClientIDMode="Static" />
Then add at
Javascript
<pre>$("#hfProduct").val(score);
hfProduct is your HiddenField ID and score at javascript is the value you want to take.
Then at
.aspx.cs add this
string score;
score = hfProduct.Value.ToString();
