App({//如下为小程序的生命周期
  onLaunch: function() { },//监听初始化
  onShow: function() {  },//监听显示（进入前台）
  onHide: function() {  },//监听隐藏（进入后台：按home离开微信）
  onError: function(msg) {  },//监听错误
  //如下为自定义的全局方法和全局变量  
  globalFun:function(){},
  globalData: 'I am global data'})

Page({
  data: {text: "This is page data."},//页面数据，用来维护视图，json格式
  onLoad: function(options) {  },//监听加载
  onReady: function() {  },//监听初次渲染完成
  onShow: function() {  },//监听显示
  onHide: function() {  },//监听隐藏
  onUnload: function() {  },//监听卸载
  onPullDownRefresh: function() {  },//监听下拉
  onReachBottom: function() {  },//监听上拉触底
  onShareAppMessage: function () {  },//监听右上角分享
  //如下为自定义的事件处理函数（视图中绑定的）
  viewTap: function() {//setData设置data值，同时将更新视图
    this.setData({text: 'Set some data for updating view.'})
  }
})

<!--{{}}绑定data中的指定数据并渲染到视图--><view class="title">{{text}}</view><!--wx:for获取数组数据进行循环渲染，item为数组的每项--><view wx:for="{{array}}"> {{item}} </view><!--wx:if条件渲染--><view wx:if="{{view == 'WEBVIEW'}}"> WEBVIEW </view><view wx:elif="{{view == 'APP'}}"> APP </view><view wx:else="{{view == 'MINA'}}"> MINA </view><!--模板--><template name="staffName">
  <view>FirstName: {{firstName}}, LastName: {{lastName}}</view></template><template is="staffName" data="{{...template.staffA}}"></template><template is="staffName" data="{{...template.staffB}}"></template><!--bindtap指定tap事件处理函数为ViewTap--><view bindtap="ViewTap"> 点我点我 </view>

Page({
  data: {//data数据主要用于视图绑定
    text:"我是一条测试",
    array:[0,1,2,3,4],

    template:{
        staffA: {firstName: 'Hulk', lastName: 'Hu'},

    }
  },
  ViewTap:function(){console.log('额，点到我了了~')}//自定义事件，主要用于事件绑定})
