1. 组件化编码流程（通用）

实现静态组件：抽取组件，使用组件实现静态页面效果
展示动态数据：

数据的类型、名称是什么？
数据保存在哪个组件？

交互——从绑定事件监听开始

2. 页面组件的划分

3. 静态页面代码

4. 静态页面组件化拆分

App.vue

<template>
  <div class="todo-container">
    <div class="todo-wrap">
      <TodoAddTask></TodoAddTask>
      <TodoList></TodoList>
      <TodoSituation></TodoSituation>
    </div>
  </div>
</template>
<script>
// 导入子组件
import TodoAddTask from './components/TodoAddTask.vue'

    ></TodoItem>    
  </ul>
</template>
<script>

import TodoItem from './TodoItem.vue'
export default {
  name: 'TodoList',
  components: {TodoItem},
  data() {
    return {
      todos: [
        {id: '001', todo: '吃饭', done: true},
        {id: '002', todo: '睡觉', done: false},

  border: 1px solid #ddd;
  border-radius: 2px;
  padding-left: 5px;
  margin-top: 10px;
}
</style>

TodoItem.vue

<template>
  <li>
    <label>
      <!-- 使用v-bind绑定checked属性，true则有这个属性，false无这个属性 -->
      <input type="checkbox" :checked="todoObj.done"/>
      <span>{{todoObj.todo}}</span>
    </label>
    <button class="btn btn-danger" style="display:none">删除</button>
  </li>
</template>
<script>
export default {
  name: 'TodoItem',
  props: ['todoObj']
}
</script>
<style scoped>
/*item*/
li {
  list-style: none;
  height: 36px;
  line-height: 36px;
  padding: 0 5px;
  border-bottom: 1px solid #ddd;
}
li label {
  float: left;
  cursor: pointer;
}
li label li input {
  vertical-align: middle;
  margin-right: 6px;
  position: relative;
  top: -1px;
}
li button {
  float: right;
  display: none;
