var util = require('../../utils/util.js')

    logs: [
    ]

    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
    })
  }
})
 

作為一個新手，看不懂demo，就拆分了一下。我是看懂了。

然後就解決了我的問題。

<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 () {
    //獲取網路資料
    var test = [
  { "title": "張三", "content": "張三現在不太高興", "url": "https://chongnb.com/mana/05563814469562242.jpg" },

               ]
    //設定資料
    this.setData({
      logs: test
    })
  }
})
