javascript - How does the applet wx.request render all data to index.wxml

Question

I have been learning small programs recently, and I just learned wx.request. I used php mysql to output a json data format, link: http://www.likeyunba.com/tmp/...

I want to render this data on the mini program page.
index.wxml

<!--index.wxml-->
<view class="container">
  <view  bindtap="bindViewTap" class="userinfo">
    <image class="userinfo-avatar" src="{{userInfo.avatarUrl}}" background-size="cover"></image>
    <text class="userinfo-nickname">{{post.id}}</text>
  </view>
  <view class="usermotto">
    <text class="user-motto">{{motto}}</text>
    <text class="user-motto">{{post.title}}</text>

    <image class="userinfo-avatar" src="{{post.imgurl}}" background-size="cover"></image>

    <text class="user-motto">{{post.url}}</text>
    <text class="user-motto">{{post.int}}</text>
  </view>
</view>

index.js

//index.js
//获取应用实例
var app = getApp()
Page({
  data: {
    userInfo: {},
    post:[]
  },
  //事件处理函数
  bindViewTap: function() {
    var that = this;
    wx.request({
    url: 'http://www.likeyunba.com/tmp/json.php',
    method:'GET',
    success: function(res){
      console.log(res);
      that.setData({
        post:res.data[0]
      })
    },
    fail: function(res) {
      console.log("--fail--")
    }
  })



  },
  onLoad: function () {
    console.log('onLoad')
    var that = this
    //调用应用实例的方法获取全局数据
    app.getUserInfo(function(userInfo){
      //更新数据
      that.setData({
        userInfo:userInfo
      })
    })
  }
})

When the page is refreshed, my WeChat avatar will be displayed. Clicking on the WeChat avatar will render the json format data output by PHP.

But my http://www.likeyunba.com/tmp/... has two pieces of data, but the page only renders one piece. Is there any way to render all the data? And when I insert new data into the database, the mini program page also renders the latest data.

Answer 1

There are two pieces of json data. You must use wx:for. Directly assign res.data to post instead of data[0], so there must be only one piece.
You can take a look at the official documentation on how to use wx:for.
Otherwise, take a look at a small program demo I made: https://github.com/lin-xin/wx...
Familiarize yourself with this example, and your small program will basically be very good
