wx:for, wx:key improves performance and provides a unique identifier for each traversed individual. Each individual traversed is item

 <!-- 
在组件上使用 wx:for 控制属性绑定一个数组,即可使用数组中各项的数据重复渲染该组件。
默认数组的当前项的下标变量名默认为 index,数组当前项的变量名默认为 item 
-->
  <view wx:for=&#39;{{listArray}}&#39; wx:key=&#39;{{index}}&#39;>
    <view>
      <!-- 把数据item传递给模板,使用三点运算符的方式,模板那边就可以直接用属性名获取数据了,不用再xxx.xxx来获取数据 -->
