javascript - Vue搜索过滤器复选框问题

Question

我对数组的复选框和 vue 过滤器有问题。

new Vue({
  el: "#app",
  data: {
    todos: [
      { text: "Learn JavaScript"},
      { text: "Learn Vue"},
      { text: "Play around in JSFiddle"},
      { text: "Build something awesome"}
    ],
    search: '',
  },
  methods: {
  	
  },
  computed: {
  	filtered() {
      return this.todos.filter(todo => {
        return todo.text.toLowerCase().includes(this.search.toLowerCase())
      })
    },
  }
})

body {
  background: #20262E;
  padding: 20px;
  font-family: Helvetica;
}

#app {
  background: #fff;
  border-radius: 4px;
  padding: 20px;
  transition: all 0.2s;
}

li {
  margin: 8px 0;
}

h2 {
  font-weight: bold;
  margin-bottom: 15px;
}

del {
  color: rgba(0, 0, 0, 0.3);
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
  <input type="text" v-model="search">
  <ol>
    <li v-for="todo in filtered">
      <label>
        <input type="checkbox">

        <del v-if="todo.done">
          {{ todo.text }}
        </del>
        <span v-else>
          {{ todo.text }}
        </span>
      </label>
    </li>
  </ol>
</div>

如果您首先从数组中检查并搜索任何其他人：

检查 -> 学习 javascript

搜索 -> 学习 Vue

Vue似乎被检查了..

是不是应该这样工作？

如何从显示的列表中删除所有内容并同时追加？

用于v-model在filtered数组中绑定

new Vue({
  el: "#app",
  data: {
    todos: [
      { text: "Learn JavaScript"},
      { text: "Learn Vue"},
      { text: "Play around in JSFiddle",done:true},
      { text: "Build something awesome"}
    ],
    search: '',
  },
  methods: {
  	
  },
  computed: {
  	filtered() {
      return this.todos.filter(todo => {
        return todo.text.toLowerCase().includes(this.search.toLowerCase())
      })
    },
  }
})

body {
  background: #20262E;
  padding: 20px;
  font-family: Helvetica;
}

#app {
  background: #fff;
  border-radius: 4px;
  padding: 20px;
  transition: all 0.2s;
}

li {
  margin: 8px 0;
}

h2 {
  font-weight: bold;
  margin-bottom: 15px;
}

del {
  color: rgba(0, 0, 0, 0.3);
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
  <input type="text" v-model="search">
  <ol>
    <li v-for="todo in filtered">
      <label>
        <input v-model="todo.done" type="checkbox">
          <del v-if="todo.done">{{ todo.text }}</del>
          <span v-if="!todo.done">{{ todo.text }}</span>
          
      </label>
    </li>
  </ol>
</div>

这里是默认选中的Play around in JSFiddle
