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'

 },
 watch:{

  deep:true  //深度复制
  }
 },
 methods:{
 tooglefinish(item){
  item.isfinished = !item.isfinished

 addnew(){
  this.items.push({
  label:this.newitem,
  isfinished:false,
