Javascript can read the list using for loop.
e.g

 [WebMethod]

    public static List<EmpName> GetData(int startIndex, int maximumRows, string sort, string filter)

    {

        var emp = objClient.GetData(startIndex, maximumRows, sort, filter);

        List<EmpName> lstEmp = new List<EmpName>();

        foreach (var item in emp)

        {

            EmpName objEmp = new EmpName();

            objEmp.ID = item.ID;

            objEmp.Name = item.Name;

            lstEmp.Add(objEmp);

        }

        return lstEmp;

    }



Javascript:

function ReadList(lstEmp)

{

     for(var i=0;i<lstEmp.length;i++)

     {

          alert(lstEmp[i].ID+ + lstEmp[i].Name);

     }

}

I want to create a list in javascript i.e List to perform various operation at client side how it can be achieved?
