案例知识点：

1.vue.js基础知识

2.HTML5 本地存储localstorage

store.js代码

const STORAGE_KEY = 'todos-vue.js'export default{ fetch(){ return JSON.parse(window.localStorage.getItem(STORAGE_KEY) || '[]') }, save(items){ window.localStorage.setItem(STORAGE_KEY,JSON.stringify(items)); }}

App.vue代码

<template> <div id="app"> <h1 v-text="title"></h1> <input v-model="newItem" v-on:keyup.enter="addNew"/> <ul> <li v-for="item in items" v-bind:class="{finished:item.isFinished}" v-on:click='toogleFinish(item)'> {{item.label}} </li> </ul> </div></template><script>import Store from './store'export default { name: 'app', data () { return { title: 'this is a todo list', items:Store.fetch(), newItem:'' } }, watch:{ items:{ handler(items){ //经过变化的数组会作为第一个参数传入 Store.save(items) console.log(Store.fetch()); }, deep:true //深度复制 } }, methods:{ toogleFinish(item){ item.isFinished = !item.isFinished }, addNew(){ this.items.push({ label:this.newItem, isFinished:false, }) this.newItem = '' } }}</script><style>#app { font-family: 'Avenir', Helvetica, Arial, sans-serif; -webkit-font-smoothing: antialiased; -moz-osx-font-smoothing: grayscale; text-align: center; color: #2c3e50; margin-top: 60px;}.finished{ text-decoration: underline;}</style>
