如何更改基于该属性的mongodb对象的属性和样式

Question

当试图选中复选框或按下按钮，然后将字体更改为删除线时，我试图使待办事项状态属性从活动更改为完成。我应该制作一个使用更新后功能的单独功能，还是应该专门为此制作一条新的路线？

提交待办事项后，它会从state属性中进入“活动”状态。

此外，如何获取复选框的状态，以了解是否已选中该复选框？

基于此，我想将文本更改为具有删除线，并更新我检查为完整的元素的state属性。

<template lang="html">
  <div>
    <form v-on:submit='addTodo($event)'>
      <input type='text' placeholder='Add or edit a todo' v-model='newTodo'/>
      <textarea placeholder='Add or edit a description' v-model='newDescription'></textarea>
      <input type='submit' />
    </form>
    <ul> 
      <li v-for='todo in todos' :key='todo._id'>
        <input type='checkbox'>
        <button @click="deleteTodo(todo._id)">X</button>
        <p>{{todo.title}}</p>
        <p>{{todo.description}}</p>
        <button @click="updateTodo(todo._id)">Edit</button>
      </li>
    </ul>
  </div>
</template>
