b'coz javascript run on client side ok
when you press server button code it will postback to the server?
the question is how to know server client side calculation that you perfom with javascript?
Only one solution?

you have to make one static variable at server side this static variable is class level ok

you can use raisecallbackeventhandler interface and implement method in .cs file.

this means when you press html button whatever value calculate it will passed on server side static variable.

Assign static varible
private static int Value;

use code on page load :

String cbReference =
Page.ClientScript.GetCallbackEventReference(this,
"arg", "ReceiveServerData", "context");
String callbackScript;
callbackScript = "function CallServer(arg, context)" +
"{ " + cbReference + ";}";
Page.ClientScript.RegisterClientScriptBlock(this.GetType(),
"CallServer", callbackScript, true);

you must implement Icallback event handler interface

Like
public partial class NewsDetails : System.Web.UI.Page,ICallbackEventHandler

Implement method in same .cs
public String GetCallbackResult()
{ return "true"; }
public void RaiseCallbackEvent(String eventArgument)
{
value = eventArgument;
}

after write javascript

whatever calculation is made
Pass javascript through

Like

CallServer("YourNewCalculateValue","");
