What I have tried:

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <script src="../Scripts/jquery-1.10.2.js"></script>
    <script src="../Scripts/Test.js"></script>
</head>
<body>

ASP.NET

<form id="form1" runat="server">

HTML

        <input id="btnTest" type="button" onclick="CallFunction()" />
    </form>
</body>
</html>

-------------------------------------------------------------------------
Test.js

JavaScript

function CallFunction()
{

    $.ajax({
        type: "POST",
        url: "../DataService/GetData",
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function (response) {
            var names = response.d;
            alert(names);
        },
        failure: function (response) {
            alert(response.d);
        }
    });
}

---------------------------------------------------------------------------------
DataService.cs

C#

using System.Web;
using System.Web.Script.Serialization;
using System.Web.Services;

/// <summary>
/// Summary description for DataService
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
    [System.Web.Script.Services.ScriptService]
    public class DataService : System.Web.Services.WebService
    {

        [WebMethod (EnableSession=true)]
        public string GetData()
        {
            Dictionary<string, string> name = new Dictionary<string, string>();
            name.Add("1", "Sourav Kayal");
            name.Add("2", "Ram mishra");
            string myJsonString = (new JavaScriptSerializer()).Serialize(name);
            return myJsonString;
        }
    }

Does it work? What error did you get?

Abhijit Parab 17-Dec-16 13:28pm

It didn't work. I didn't get any error. When I was debugging $.ajax method got called but it didn't call WebMethod. No success or failure.

Are you using correct endpoints?

Abhijit Parab 17-Dec-16 13:38pm

It is not a WCF service. If you see my mentioned file paths and code, I have created a class file with attribute scriptservice. In the same class file I have defined WebMethod. I want to call that webmethod from javascript file using jquery Ajax method. But it is not getting called

WebMethods are normally static methods, it would not work if it is not made static according to my knowledge, try adding static keyword in method signatures, hope it helps

For reference you can have a look at this blogpost (Calling a Webmethod Using Jquery Ajax)
