如何根据v-for值在我的模式窗口(单击按钮时)上获取所选数据？

data() {
  return {
    selectedItem: null,
    items: [
      { id: 1, name: 'Item 1' },
      { id: 2, name: 'Item 2' },
      { id: 3, name: 'Item 3' }
    ]
  }
}

<template>
  <div>
    <button @click="showModal">打开模态窗口</button>
    <div v-if="selectedItem">
      你选择了：{{ selectedItem.name }}
    </div>
    <div v-if="showModalFlag">
      <div v-for="item in items" :key="item.id" @click="selectItem(item)">
        {{ item.name }}
      </div>
    </div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      selectedItem: null,
      items: [
        { id: 1, name: 'Item 1' },
        { id: 2, name: 'Item 2' },
        { id: 3, name: 'Item 3' }
      ],
      showModalFlag: false
    }
  },
  methods: {
    showModal() {
      this.showModalFlag = true;
    },
    selectItem(item) {
      this.selectedItem = item;
      this.showModalFlag = false;
    }
  }
}
</script>
