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

var util = require('../../utils/util.js')Page({  data: {    logs: [    ]  },  onLoad: function () {    var test = wx.getStorageSync('logs');    var tset1 = test || [];    var test3 = function (log) {      return util.formatTime(new Date(log));    }    var test2 = tset1.map(test3);    this.setData({      logs: test2    })  }})

作为一个新手，看不懂demo，就拆分了一下。我是看懂了。

然后就解决了我的问题。

<view class="container log-list">  <block wx:for="{{logs}}" wx:for-item="log" wx:key="*this">    <view class="classname">      <text class="log-item"> {{log.title}}</text>    </view>    <view class="classname">      <text class="log-item"> {{log.content}}</text>    </view>    <view class="classname">      <text class="log-item">{{log.url}}</text>    </view>  </block></view>

Page({  data: {    logs: []  },  onLoad: function () {    //获取网络数据    var test = [  { "title": "张三", "content": "张三现在不太高兴", "url": "https://chongnb.com/mana/05563814469562242.jpg" }, { "title": "李四", "content": "李四可能很高兴", "url": "https://chongnb.com/mana/05563814469562242.jpg" }, { "title": "王五", "content": "王五现在不太高兴", "url": "https://chongnb.com/mana/05563814469562242.jpg" }               ]    //设置数据    this.setData({      logs: test    })  }})
