<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

    <script src="jquery.js" type="text/javascript"></script>

    <script src="JScriptuserNTID.js" type="text/javascript"></script>
    
</head>
<body>
    <form id="form1" runat="server">
    <div>
Employee's NTID: <input type="text" id = "Eid" name="Employee_NTID" />
<br />
<br />
    <button type = "button" id = "callingMethod" class ="start">Search</button> 
    </div>
    </form>
</body>
</html>

Here is JScriptuserNTID.js file:

//var ajax_load = "<img src='loading.gif' alt='loading...' />";

//  load() functions
//var loadUrl = "test.txt";

$(document).ready(function() {

        //data: ("Employee NTID :" + eNtid),
        error: function(XMLHttpRequest, textStatus, errorThrown) {
            alert(textStatus);
        },
        success: function(result) {

using System.Web;
using System.Web.Services;

/// <summary>
/// Summary description for WebService
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 
 [System.Web.Script.Services.ScriptService]
public class WebService : System.Web.Services.WebService {

    public WebService () {

        //Uncomment the following line if using designed components 
        //InitializeComponent(); 
    }

    [WebMethod]
    public void HelloWorld() {
        Console.WriteLine( "Hello World" );
    }
    
}
