store.js 调用错误
<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="toggleFinished(item)">
{{item.label}}
</li>
</ul>
</div>
</template>
<script>
import Store from'./store.js'
export default {
data:function(){
return{
title:'shuiguo title',
items:Store.fetch(),
newItem:''
}
},
watch:{
items:{
handler:function(items){
Store.save()
},
deep:true
}
},
methods:{
toggleFinished:function (item){
item.isFinished=!item.isFinished
},
addNew:function(){
this.items.push(
{
label:this.newItem,
isFinished:true
}),
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{
color:red;
}
</style>
下面是store.js
const STORAGE_KEY="todos-vuejs"
export default{
fetch:function(){
return JSON.parse(
window.localStorage.getItem(
STORAGE_KEY||"[]"
)
)
},
save:function(items){
window.localStorage.setItem(
STORAGE_KEY,JSON.stringify(items)
)
}
}
