使用vuejs做一个todolist

在输入框内输入一个list，回车，添加到list列表中，点击列表中的项样式改变

 

1、index.html

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <title>my-first-vue-project</title>
  </head>
  <body>
    <div id="app"></div>
    <!-- built files will be auto injected -->
  </body>
</html>

2、main.js

// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
import App from './App'

Vue.config.productionTip = false

/* eslint-disable no-new */
new Vue({
  el: '#app',
  template: '<App/>',
  components: { App }
})

3、App.vue

<template>
  <div id="app">
    <h1>{{title}}</h1>
    <h1 v-text="title"></h1>
    <h1 v-html="title"></h1>
    <input type="text" v-model="newItem" v-on:keyup.enter="addNew">
    <ul>
        <li v-for="item in items" v-bind:class="{finished:item.isFinished}" v-on:click="toggleFinish(item)">
        {{item.label}}
        </li>
    </ul>

  </div>
</template>

<script>

export default {
  
   data () {
    return {
      title: '<span>?</span>this is a todolist',
      items:[
          {
            label:'coding',
            isFinished:false
  
          },
          {
            label:'walking',
            isFinished:true
  
          }
      ],
      newItem:''
    }
  },
  methods:{
    toggleFinish:function(item){
      // console.log(item);
      item.isFinished=!item.isFinished;
    },
    addNew:function(){
      // this.newItem;
      // console.log(this.newItem);
      this.items.push({
        label:this.newItem,
        isFinished:false
      })
      this.newItem='';
    }
  }
}
</script>

<style>
.finished{
  text-decoration:underline;
}
#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;
}
</style>
