如何通过ID字段从存储在Vuex中的对象数组中获取项？

state: {
  items: [
    { id: 1, name: 'item1' },
    { id: 2, name: 'item2' },
    { id: 3, name: 'item3' }
  ]
}

getters: {
  getItemById: (state) => (id) => {
    return state.items.find(item => item.id === id);
  }
}

import { mapGetters } from 'vuex';

export default {
  computed: {
    ...mapGetters(['getItemById'])
  },
  methods: {
    getItem() {
      const itemId = 2;
      const item = this.getItemById(itemId);
      console.log(item);
    }
  }
}
