$.ajax({
type: "POST",
url: "../loadmapstring.asmx/bindMapLocations",
data: "{s:sParam}", // passing the parameter
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(retValue) {
// Do something with the return value from.Net method
generateMarkersForSideBar(retValue);
}
});


i tried this but its not working

C#
public static void calculate(string par)
      {
          // Cleans the message to allow single quotation marks
          string cleanMessage = par.Replace("'", "\\'");
          string script = string.Format("<script type=\"text/javascript\">$(document).ready(function(){JA('{0}');});</script>", cleanMessage);

          // Gets the executing web page
          Page page = HttpContext.Current.CurrentHandler as Page;
          // Checks if the handler is a Page and that the script isn't allready on the Page
          if (page != null && !page.ClientScript.IsClientScriptBlockRegistered("JA"))
          {
              page.ClientScript.RegisterClientScriptBlock(typeof(<your class="" name="">), "JA", script);
          }
      }</your>

but how do i call this C# function?
You can using ajax jquery

JavaScript
function JA(location)
{
$.ajax({
            type: 'POST',
            url: "ControllerName/calculate",
            data: dataForPost,
            success: function (returnValue) {}
        });
 
}

make an ajax call
and if using web forms, then make the c# method as [WebMethod] before ajax call.

Hi,
Use this line after getting result from your C# function


Page.ClientScript.RegisterStartupScript(this.Page.GetType(), "sScript", "<script language='javascript'>MyJSfunction( PassResultStringOfC#CodeAsParameter );</script>");
