小程序是采用MINA框架
<!--demo.wxml-->
<view> Hello {{name}}</view>
<button bindtap="changeName">Click Me</button>
// demo.js
var helloData = {
name: 'WeChat'
}
Page({
/**
* 页面的初始数据
*/
data: helloData,
changeName: function (e) {
this.setData({
name: 'MINA'
})
}
})
开发者通过框架将逻辑层数据库中的name与视图层的name进行了绑定，所以在页面一打开的时候会显示Hello WeChat 。
当点击按钮的时候，视图层会发送changeName的事件给逻辑层，逻辑层找到对应的事件处理函数。
逻辑层执行了setData的操作，将name从WeChat 变为 MINA，因为该数据和试图层已经绑定了，从而视图层会自动改变为Hello MINA。
微信小程序不仅在底层架构的运行机制上做了大量的优化，还在重功能（如page切换、tab切换、多媒体、网络连接等）上使用接近于native的组件承载。所以微信小程序MINA有着接近原生App的运行速度，做了大量的框架层面的优化设计，对Android端和iOS端做了高度一致的呈现，并且准备了完备的开发和调试工具。
小程序配置
全局配置app.json
进行pages配置String Array，window配置Object，tabBar配置Object，networkTimeout配置Object，debug配Boolean置。
