为什么设置了宽高100%左边显示的还有，不是应该啥都没了吗，我看老师的都没了，我index.js页面代码也都是复制的老师的，app.json里面的配置也跟老师的一样

相关代码：

//index.js
//获取应用实例
const app = getApp()

Page({
  data: {
    motto: 'Hello World from vscode',
    userInfo: {},
    hasUserInfo: false,
    canIUse: wx.canIUse('button.open-type.getUserInfo'),
    setting: {
      skew: 0,
      rotate: 0,
      showLocation: false,
      showScale: false,
      subKey: '',
      layerStyle: -1,
      enableZoom: true,
      enableScroll: true,
      enableRotate: false,
      showCompass: false,
      enable3D: false,
      enableOverlooking: false,
      enableSatellite: false,
      enableTraffic: false,
    },
    location: {
      latitude: 31,
      longitude: 120,
    },
    scale: 10,
    markers: [
      {
        iconPath: "/resources/car.png",
        id: 0,
        latitude: 23.099994,
        longitude: 113.324520,
        width: 50,
        height: 50
      },
      {
        iconPath: "/resources/car.png",
        id: 1,
        latitude: 23.099994,
        longitude: 114.324520,
        width: 50,
        height: 50
      },
    ]
  },
  //事件处理函数
  bindViewTap: function() {
    wx.navigateTo({
      url: '../logs/logs?color=blue'
    })
  },
  onShow: function() {
    console.log('lifecycle: index onShow')
  },
  onHide: function() {
    console.log('lifecycle: index onHide')
  },
  onReady: function() {
    console.log('lifecycle: index onReady')
  },  
  onUnload: function() {
    console.log('lifecycle: index onUnload')
  },
  onLoad: function () {
    console.log('lifecycle: index onLoad')
    if (app.globalData.userInfo) {
      this.setData({
        userInfo: app.globalData.userInfo,
        hasUserInfo: true
      })
    } else if (this.data.canIUse){
      // 由于 getUserInfo 是网络请求，可能会在 Page.onLoad 之后才返回
      // 所以此处加入 callback 以防止这种情况
      app.userInfoReadyCallback = res => {
        this.setData({
          userInfo: res.userInfo,
          hasUserInfo: true
        })
      }
    } else {
      // 在没有 open-type=getUserInfo 版本的兼容处理
      wx.getUserInfo({
        success: res => {
          app.globalData.userInfo = res.userInfo
          this.setData({
            userInfo: res.userInfo,
            hasUserInfo: true
          })
        }
      })
    }
  },
  getUserInfo: function(e) {
    console.log(e)
    app.globalData.userInfo = e.detail.userInfo
    this.setData({
      userInfo: e.detail.userInfo,
      hasUserInfo: true
    })
  },
  onBtnTap: function() {
    this.setData({
      motto: 'button clicked'
    })
  }
})
