vue3-todoMVC练习

todoMVC 简介

参照todeMVC网站，复制样式，做个类似的例子。打开NewWork,找到todomvc-app-css的index.css,放到本地就可以了。

CODE

啥也别说了，上才艺

    <section class="main">
      <input id="toggle-all" type="checkbox" class="toggle-all" />
      <label for="toggle-all">Mark all as complete</label>
      <ul class="todo-list">
        <li v-for="todo in todos" class="todo" :key="todo.id">
          <div class="view">
            <input type="checkbox" :value="todo.isCheck" class="toggle" />
            <label>{{todo.title}}</label>
