  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）

  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-->

  <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-->
