（21）打鸡儿教你Vue.js
组件化思想：
组件化实现功能模块的复用
高执行效率
开发单页面复杂应用
组件状态管理（vuex）
多组件的混合使用 vue-router
代码规范

<template>
<div>
hello info component
</div>
</template>
<script>
export default {
name: "Info"

<div id="app">
<div id="nav">

单向数据流概念
view actions stateVuex多个视图依赖，菜单导航
不同视图的行为需要变更同一状态，评论弹幕
vue.js开发的状态管理模式 组件状态集中管理
import Vue from 'vue'
import Vuex from 'vuex'
Vue.use(Vuex)
export default new Vuex.Store({
state: {
},
mutations: {
},
actions: {
}
})组件的状态 改变状态的方法集
<template>
<div>
hello info component
<button type="button" @click="add()">添加</button>
</div>
</template>
<script>
import store from '@/store'
export default {
name: 'Info',
store,
methods: {
add () {
console.log('dashucoding')
}
}
}
</script>
<style scoped>

increase () {
this.state.count++

})调式
<script>
import store from '@/store'
export default {
name: 'Info',
store,
methods: {
add () {
console.log('add Event form info!')
// alert('alert form info')
debugger
