与上一篇Vue中TodoList案例_底部统计有俩个文件变化了

App.vue：定义了一个方法checkAllTodo，实现全选和取消全选，并将方法传给儿子组件MyFooter

<template>
  <div id="root">
    <div class="todo-container">
      <div class="todo-wrap">
        <MyHeader :addTodo="addTodo"/>
        <MyList :todos="todos" :checkTodo="checkTodo" :deleteTodo="deleteTodo"/>
        <MyFooter :todos="todos" :checkAllTodo="checkAllTodo"/>
      </div>
    </div>
  </div>

</template>

<script>
import MyHeader from './components/MyHeader'
import MyList from './components/MyList'
import MyFooter from './components/MyFooter'

export default {
  name:'App',
  components:{MyHeader,MyList,MyFooter},
  data(){
    return{
      todos:[
        {id:'001',title:'唱',done:true},
        {id:'002',title:'跳',done:false},
        {id:'003',title:'rap',done:true},
        {id:'004',title:'篮球',done:true}
      ]
    }
  },
  methods:{
    //添加一个todo
      addTodo(todoObj){
        this.todos.unshift(todoObj)
    },
    //勾选or取消勾选一个todo
    checkTodo(id){
        this.todos.forEach((todo)=>{
          if (todo.id===id)todo.done=!todo.done
        })
    },
    //删除一个todo
    deleteTodo(id){
        this.todos = this.todos.filter((todo)=>{
            return todo.id !==id
        })
    },
    //全选or取消全选
    checkAllTodo(done){
        this.todos.forEach((todo)=>{
          todo.done = done
        })
    }
  }
}
</script>
