                success: function () {                                      
                },
                error: function (jqXHR, textStatus, errorThrown) {
                }

        }

        [WebMethod]
        [ScriptMethod]
        public void SignOut()       
        {                       
            HttpContext.Current.Session.Abandon();
            HttpContext.Current.Response.Redirect("Login.aspx");
        }

Use like following.  This is a sample example from my running application.

Script

/*Save Data*/
function SaveData()
{
    var roleInfoList = [];
    var len = $('#gvRoleInfo tr').length;
    var count = 0;
    
    $('#gvRoleInfo tr').each(function()
    {
        if (!this.rowIndex) return; // Skip first row 
        var flag = $(this).find('.uflag').text();
        if(flag == 1) return; //Object should not create if it is unchanged item
        
        var rolNm = $(this).find('.roleName').text();
        var id = $(this).find('.roleId').text();    
        var roleInfo = { roleNm: rolNm, roleId: id, updateFlag: flag};
        roleInfoList[count] = roleInfo;
        count++;
    });
    
    if(roleInfoList.length < 1)
        return;
        
    $.ajax({
        type: "POST",
        url: "Services/ApplicationService.asmx/SaveRoleInfo?refCode=RoleInfo",
        data: "{'roleInfoList':" + JSON.stringify(roleInfoList) + "}",
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        error: function(xhr, errorType, exception) 
        {
            var err = eval("(" + xhr.responseText + ")");
            //Display Error Message.
            alert(err.Message);
        },
        success: function(msg) 
        { 
            getAllRollInfo();
            alert(msg.d);
        },
        failure: function() 
        { 
            alert("System can not retrive data \nPlease contact with system administrator"
                    + "\nHints: Webservice didn't response.");   
         }
    });
}

C# code, Web service

public class ApplicationService : System.Web.Services.WebService
{
    private readonly IRoleInfoBLL _objRoleInfoBLL;
    public ApplicationService()
    {
        string strModelName =  Context.Request.QueryString["refCode"];

        else if (strModelName == "RoleInfo")
        {
            _objRoleInfoBLL = StructureMap.ObjectFactory.GetNamedInstance<IRoleInfoBLL>("RoleInfoBLL");
        }
   }

    [WebMethod]
    public string SaveRoleInfo(List<object> roleInfoList)
    {
        string message = "";

        foreach (var roleInfo in roleInfoList)
        {
            object roleInfoObj = roleInfo;
            Dictionary<string, object> tmp = (Dictionary<string, object>)roleInfoObj;

            object rl_flag = null;
            object rl_id = null;
            object rl_nm = null;
            
            tmp.TryGetValue("updateFlag", out rl_flag);
            tmp.TryGetValue("roleId", out rl_id);
            tmp.TryGetValue("roleNm", out rl_nm);


            int uFlag = Convert.ToInt32(rl_flag.ToString());
            int roleId = Convert.ToInt32(rl_id.ToString());
            string roleNm = rl_nm.ToString();

            if (uFlag == 1) // For existing data
                continue;

            RoleInfo objRoleInfo = new RoleInfo();
            objRoleInfo.Role_Id = roleId;
            objRoleInfo.RoleName = roleNm;
            objRoleInfo.UserId = 1; // Hard Coded ... Should come from session user id//


            if (uFlag == 2) // For New insert
            {
                try
                {
                    message = _objRoleInfoBLL.SaveRoleInfo(objRoleInfo);
                }
                catch (Exception exp)
                {
                    throw (exp);
                }
            }
            else if (uFlag == 3) //For Update
            {
                try
                {
                    message = _objRoleInfoBLL.EditRoleInfo(objRoleInfo);
                }
                catch (Exception exp)
                {
                    throw (exp);
                }
            }

        }

        return message;
    }
}

Make sure that you have un commented the following class attribute in your service class so that it will allow Scripts/Ajax calls.

[System.Web.Script.Services.ScriptService]
