                   }]
            }
            //......................................
         ]
         */

jQuery解析Json并循环读取内容

//=========首页头部商品分类=========
function SelIndustryProductTypeData(IndustryID, CompanyID) {
    $.ajax({
        url: '/Home/AjaxService/SelIndustryProductTypeData.ashx',
        type: 'GET',
        data: { industryid: IndustryID, companyid: CompanyID },
        success: function (data) {
            var dt = eval("(" + data + ")");
            var item = "";

            $.each(dt, function (index) {

                item += "<dt class=\"mt15\">";
                item += "<p class=\"font14 bold\">" + dt[index].ProductTypeName + "</p>";
                item += "<span><img src=\"/images/index_iocn3_03.jpg\" width=\"12\" height=\"12\" /></span>";
                item += "</dt>";
                item += "<dd>";

                var dr = dt[index].ProData;
                $.each(dr, function (num) {
                    item += "<a href=\"#\">" + dr[num].TypeName + "</a>";
                });
                item += "</dd>";
            });

            $("#nav-top").html(item);
        }
    });
}
