在Vue 3中使用v-model在数组中进行搜索

<template>
  <input type="text" v-model="searchText" @input="handleInput" placeholder="Search...">
</template>

<script>
export default {
  props: {
    value: {
      type: String,
      default: ''
    }
  },
  data() {
    return {
      searchText: this.value
    };
  },
  methods: {
    handleInput() {
      this.$emit('input', this.searchText);
    }
  }
};
</script>

<template>
  <div>
    <search-input v-model="searchText"></search-input>
    <ul>
      <li v-for="item in filteredItems" :key="item.id">{{ item.name }}</li>
    </ul>
  </div>
</template>

<script>
import SearchInput from './SearchInput.vue';

export default {
  components: {
    SearchInput
  },
  data() {
    return {
      searchText: '',
      items: [
        { id: 1, name: 'Apple' },
        { id: 2, name: 'Banana' },
        { id: 3, name: 'Orange' }
      ]
    };
  },
  computed: {
    filteredItems() {
      return this.items.filter(item => item.name.toLowerCase().includes(this.searchText.toLowerCase()));
    }
  }
};
</script>
