关于js的$.each问题，请教各路英雄
现在有这么一个表格

[解决办法]
    var ta_field = [{ "tbody": "code" }, { "tbody": "addr"}];
    var td0 = ""
    $.each(json.rows, function (i, item) {
        $.each(ta_field, function (j, tbody) {
            var aaa = tbody.tbody;//////////
            td0 = td0 + "<td>" + item[aaa] + "</td>";
        });
    });
