Jquery读取返回的JSON数据

1、从asmx文件返回，其实是字符串，需要特别处理

 

jquery：

 

        function GetInfo() {
            $.ajax({
                type: "POST"
                , contentType: "application/json"
                , url: "pub.asmx/GetInfo"
                , data: "{'pId':'" + _PublicId + "','userId':'" + _UserId + "'}"
                , dataType: 'json'
                , success: function(data) {
                    var json = eval（'(' + data.d + ')');
                    alert(json.flower + "," + json.egg + "," + json.isvote + "," + json.iskeep);
                }
            });
        }

 

C#：

    [WebMethod]
    public string GetInfo(int pId,int userId)
    {
	……
        return String.Format(@"{{""flower"":""{0}"",egg:""{1}"",isvote:""{2}"",iskeep:""{3}""}}"
            , dr["flower"]
            , dr["egg"]
            , Convert.ToBoolean(dr["isvote"])
            , Convert.ToBoolean(dr["iskeep"]));
    }
