小程序获取data中json格式的某个属性值

signlist: [{
        id: 0,
        title: ‘星期一‘,
        active: ""
      },
      {
        id: 1,
        title: ‘星期二‘,
        active: ""
      },
      {
        id: 2,
        title: ‘星期三‘,
        active: ""
      },
      {
        id: 3,
        title: ‘星期四‘,
        active: ""
      },
      {
        id: 4,
        title: ‘星期五‘,
        active: ""
      },
      {
        id: 5,
        title: ‘星期六‘,
        active: ""
      },
      {
        id: 6,
        title: ‘星期日‘,
        active: ""
      },
    ],

 let arr = that.data.signlist;
        for (var i = 0, len = arr.length; i < len; i++) {
          console.log(arr[i].active)
        }
