在VueJs中对对象数组中的唯一对象及其值进行分组

data() {
  return {
    items: [
      { id: 1, name: 'Apple', category: 'Fruit' },
      { id: 2, name: 'Banana', category: 'Fruit' },
      { id: 3, name: 'Carrot', category: 'Vegetable' },
      { id: 4, name: 'Tomato', category: 'Vegetable' },
      { id: 5, name: 'Orange', category: 'Fruit' },
    ]
  }
}

computed: {
  groupedItems() {
    return this.items.reduce((result, item) => {
      const key = item.category;
      if (!result[key]) {
        result[key] = [];
      }
      result[key].push(item);
      return result;
    }, {});
  }
}

<template>
  <div>
    <div v-for="(group, key) in groupedItems" :key="key">
      <h2>{{ key }}</h2>
      <ul>
        <li v-for="item in group" :key="item.id">
          {{ item.name }}
        </li>
      </ul>
    </div>
  </div>
</template>
