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>
<p 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>
</p>
</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>
总结
以上就是关于vue.js todolist实现的示例的详细内容。
