  • 数据模型中某个字段是单选或者多选的定义方式;

     1 /* jshint -W079 */

    30         receive: { t: '已领取', v: 0},
    31         unregistered: { t: '未登记', v: 1},

     9     <!-- type是传递的前面的LotteryReceiveRecord-->
    10     <!-- item传递的是LotteryReceiveRecordSchema的数据-->
    11     <!-- 原理就是,当item的某个字段与type的某个属性相同或不同时,该如何显示-->
    12     {% for t in types %}
    13     <option value="{{loop.index - 1}}" {% if item.type == t.v %}selected{% endif %}>{{t.t}}</option>
