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
vue-router
<template>
<div>
hello info component
</div>
</template>
<script>
export default {
name: "Info"
}
</script>
<style scoped>
</style>
<template>
<div id="app">
<div id="nav">
<router-link to="/">Home</router-link> |
<router-link to="/about">About</router-link> |
<router-link to="/info">Info</router-link>
</div>
<router-view/>
</div>
</template>
export default new Router({
routes: [
{
path: '/',
name: 'home',
component: Home
},
{
path: '/info',
name: 'info',
component: Info
},
Vuex
单向数据流概念
view actions state
Vuex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>
</style>
<template>
<div class="about">
<h1>This is an about page</h1>
<p>{{msg}}</p>
</div>
</template>
<script>
import store from '@/store'
export default {
name: 'about',
store,
data () {
return {
msg: store.state.count
}
}
}
</script>
<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')
store.commit('increase')
}
}
}
</script>
<style scoped>
</style>
import Vue from 'vue'
import Vuex from 'vuex'
Vue.use(Vuex)
export default new Vuex.Store({
state: {
count: 0
},
mutations: {
increase () {
this.state.count++
}
},
actions: {
}
})
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
store.commit('increase')
}
}
}
<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,
data () {
return {
msg: 'hello vue'
}
},
methods: {
add () {
console.log('dashucoding')
debugger
store.commit('increase')
},
output () {
console.log('in output')
}
}
}
</script>
<style scoped>
</style>
console.log
alert()
debugger
window对象绑定
<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,
data () {
return {
msg: 'hello vue'
}
},
mounted () {
window.vue = this
},
methods: {
add () {
console.log('dashucoding')
debugger
store.commit('increase')
},
output () {
console.log('in output')
}
}
}
</script>
<style scoped>
</style>
