以角度显示组件中许多动态过滤器计数的最佳方法

<template>
  <div>
    <input v-model="searchText" placeholder="Search">
    <ul>
      <li v-for="item in filteredItems" :key="item.id">{{ item.name }}</li>
    </ul>
    <<p>Filtered Count: {{ filteredCount }}</p>
  </div>
</template>

<script>
export default {
  data() {
    return {
      searchText: '',
      filters: [
        { id: 1, name: 'Filter 1' },
        { id: 2, name: 'Filter 2' },
        { id: 3, name: 'Filter 3' }
      ]
    };
  },
  computed: {
    filteredItems() {
      return this.filters.filter(item => item.name.includes(this.searchText));
    },
    filteredCount() {
      return this.filteredItems.length;
    }
  }
};
</script>
