各位看下这段jquery哪出错

Question

我异步得到的数据
{info:[{code:"172-32-1176",firstname:"White",lastname:"Johnson",phone:"408 496-7223",address:"10932 Bigge Rd.",city:"Menlo Park"},{code:"846-92-7186",firstname:"Hunter",lastname:"Sheryl",phone:"415 836-7128",address:"3410 Blonde St.",city:"Palo Alto"},{code:"893-72-1158",firstname:"McBadden",lastname:"Heather",phone:"707 448-4982",address:"301 Putnam",city:"Vacaville"},{code:"899-46-2035",firstname:"Ringer",lastname:"Anne",phone:"801 826-0752",address:"67 Seventh Av.",city:"Salt Lake City"},{code:"998-72-3567",firstname:"Ringer",lastname:"Albert",phone:"801 826-0752",address:"67 Seventh Av.",city:"Salt Lake City"}],str="sdf"}然后
  success: function(data) {
                    getdata(data);
                    //$("<p>").html(data).appendTo("body");
                }
            });
        });
        function getdata(data) {
            var str = "";
            $.each(data.info, function(index, value) {
                str += "编号:"+value.code+"姓"+value.firstname+"名"+value.lastname;
            });
            //$("p").html(str).appendTo("body");
        }
砸就报length为空或不是对象错误呢？

Answer 1

试试看 getdata(eval("(" + data + ")"));

Answer 2

success: function(data) {
                    getdata(data);
                    //$("<p>").html(data).appendTo("body");
                }
            });
        });
        function getdata(data) {
            var str = "";
            $.each(data.info, function() {
                str += "编号:"+this.code+"姓"+this.firstname+"名"+this.lastname;
            });
            //$("p").html(str).appendTo("body");
        }

Answer 3

var obj = eval("("+data+")");
$.each(obj.info,function(index, value){
    .......
});

Answer 4

生成数据代码：string str = "{info:[";
        for (int i = 0; i < dt.Rows.Count; i++)
        {
            str += "{code:\""+dt.Rows[i]["au_id"].ToString()+"\",firstname:\""+dt.Rows[i]["au_lname"].ToString()+"\",lastname:\""+dt.Rows[i]["au_fname"].ToString()+"\",phone:\""+dt.Rows[i]["phone"].ToString()+"\",address:\""+dt.Rows[i]["address"].ToString()+"\",city:\""+dt.Rows[i]["city"].ToString()+"\"},";
            //ToJson json = new ToJson();
            //json.AuthorCode = dt.Rows[i]["au_id"].ToString();
            //json.Name = dt.Rows[i]["au_lname"].ToString();
            //json.lastName = dt.Rows[i]["au_fname"].ToString();
            //json.phone = dt.Rows[i]["phone"].ToString();
            //json.address = dt.Rows[i]["address"].ToString();
            //json.city = dt.Rows[i]["city"].ToString();
            //authors.Add(json);
        }
        str = str.Substring(0, str.Length - 1) + "],str=\"sdf\"}";
        context.Response.Write(str);
        context.Response.Flush();客户端代码：
           success: function(data) {
                    getdata(data);
                }
            });
        });
        function getdata(data) {
            var str = "";
            $.each(data.info, function(index, value) {
                str += "编号:"+value.code+"姓"+value.firstname+"名"+value.lastname;
            });打印data：
