小程序根据下标对数组中的某个对象的元素进行赋值

<view class='right'>
        <text bindtap='label' class="{{item.bobo==true ? 'labelColor':''}}" data-index="{{index}}" data-bobo="{{item.bobo}}" wx:for="{{labelArr}}">{{item.name}}</text>
      </view>

　　

// 标签内容
    labelArr:[
      {
        name: "服务态度好",
        bobo:true,
      },
      {
        name: "排队时间短",
        bobo: false,
      },
      {
        name: "效率高",
        bobo: false,
      },
      {
        name: "门店环境好",
        bobo: false,
      },
      {
        name: "很专业",
        bobo:false,
      },
    ],
