1.提供数据 提供在公共的父组件 App.vue
2.通过父传子将数据传递给TodoMain
3.利用 v-for渲染 添加功能
1.收集表单数据 v-model
2.监听事件回车点击都要添加
3.子传父讲任务名称传递给父组件 App.vue
4.进行添加 unshift自己的数据自己负责
5.清空文本框输入的内容
6.对输入的空数据 进行判断 删除功能
1.监听事件监听删除的点击 携带id
2.子传父讲删除的id传递给父组件的App.vue
3.进行删除filter自己的数据 自己负责 底部合计父传子 传list 渲染
清空功能子传父 通知父组件 → 父组件进行更新
持久化存储watch深度监视list的变化 - 往本地存储 -进入页面优先读取本地数据
