            computed: {
                list() {
                    return this.listOrigin.filter(item => item.name.includes(this.keyword));
                }
            }
        })
</script>

其他的条件判断表现形式

return number.id < num

return number.status == true

indexOf(tempFilter[key].toString()) >= 0)

另一个比较完整的筛选

<template>
  <div>
    <input type="text" v-model="search">
    <ul>
      <!-- 注意！注意！注意！这里循环遍历的是items，不再是data里的list数组 -->
      <li v-for="(item,index) in items">
        <span>{{item.name}}</span>
        <span>{{item.msg}}</span>
        <span>{{item.age}}</span>
        <span>{{item.title}}</span>
      </li>
    </ul>
  </div>
</template>

<script>
