好人路过请进

 window.onload = function() {

        $.ajax({

            type: "POST",

            url: "GetJsonMethod.ashx",

            dataType: 'json',

            success: function(res) {

                alert(res);

                var h = "<table>";

                $(data["FirstJson"]).each(function(i, user) { h += "<tr><td>ID:" + user.Pro_ID + "</td><td>名称:" + user.Pro_Name + "</td></tr>"; });

                h += "</table>";

                $("#divResult").html(h);

            },

            error: function(res, text) {

                alert(text);

            }

        });

    }

GetJsonMethod.ashx:

string str = System.Configuration.ConfigurationManager.AppSettings["ConnectionString"];//连接字串

        System.Data.DataSet ds;//dataset

        System.Data.SqlClient.SqlConnection con = new System.Data.SqlClient.SqlConnection(@"Data Source=***");

        con.Open();

        System.Data.SqlClient.SqlCommand cmd = new System.Data.SqlClient.SqlCommand("select top 10 Pro_ID,Pro_Name from YXShop_Product", con);

        System.Data.SqlClient.SqlDataAdapter adapt = new System.Data.SqlClient.SqlDataAdapter(cmd);

        ds = new System.Data.DataSet();

        adapt.Fill(ds);

        string result = Json.DataTableToJSON(ds.Tables[0], "FirstJson");

        //result = "{success:true,data:" + result + "}";

        Response.Write(result);

        Response.End();

方法显示出来的数据：
{"FirstJson":[{"Pro_ID":"536","Pro_Name":"十全十美 - 钻石耳坠"},{"Pro_ID":"593","Pro_Name":"魔法情缘--钻石吊坠"},{"Pro_ID":"7225","Pro_Name":"珍贝--钻石戒指"},{"Pro_ID":"7226","Pro_Name":"围绕--钻石戒指"},{"Pro_ID":"7227","Pro_Name":"心花盛放--钻石戒指"},{"Pro_ID":"7228","Pro_Name":"魔力--钻石戒指"},{"Pro_ID":"7229","Pro_Name":"星雨--钻石戒指"},{"Pro_ID":"7230","Pro_Name":"花魁--钻石戒指"},{"Pro_ID":"7231","Pro_Name":"守护之心--钻石戒指"},{"Pro_ID":"7232","Pro_Name":"夺目--钻石戒指"}]}
