<view class="container log-list">
 <block wx:for-items="{{logs}}" wx:for-item="log">
 <text class="log-item">{{index + 1}}. {{log}}</text>
 </block>
</view>


 logs 页面使用 <block/> 控制标签来组织代码，在 <block/> 上使用 wx:for-items 绑定 logs 数据，并将 logs 数据循环展开节点。


//logs.js
var util = require('../../utils/util.js')
Page({
 data: {
 logs: []
 },
 onLoad: function () {
 this.setData({
  logs: (wx.getStorageSync('logs') || []).map(function (log) {
  return util.formatTime(new Date(log))
  })
 })
 }
})



运行结果如下：
