用ajax获取后台数据,返回json数据,怎么在前台使用呢?

后台

if (dataType == "SearchCustomer")
                {
                    int ID;
                    if (Int32.TryParse(CustomerID, out ID))
                    {
                        string s = GridComputer.GridCustomer.getCustomer(1, 1, ID);
                        if (s == null)
                        {
                            context.Response.ContentType = "text/plain";
                            context.Response.Write("[{\"name\":无用户,\"id\":\"0\",\"company\":\"无用户\"}]");
                        }
                        else { context.Response.Write(s); }
                    }

                } 

前台

 $(document).ready(function () {
            $("#Button3").click(
        function (SucCallback) {
            $.ajax(
            {
                type: "get",
                url: 'GridDatas.ashx', //后台处理程序   
                dataType: 'json',     //接受数据格式    
                data: 'DataType=SearchCustomer&CustomerID=' + document.getElementById("Text3").value,         //要传递的数据    
                success:SucCallback,
                error: function () { alert("error"); }
    &
