怎么实现在按下收藏按钮后出现你确定关注吗

要在按下收藏按钮后显示“你确定关注吗”的确认提示，可以使用 `ElMessageBox` 组件来实现。具体步骤如下：

1. **引入 `ElMessageBox`**：在 `<script setup>` 中引入 `ElMessageBox`。
2. **修改 `handleClick` 方法**：在 `handleClick` 方法中添加弹出确认框的逻辑。

以下是具体的代码示例：

<template>
  <div class="wrapper">
    <!-- 其他代码 -->
    <ul class="business">
      <li v-for="(item,index) in businessList" :key="index" @click="toBusinessInfo(item.businessId)">
        <img :src="item.businessImg" alt="">
        <div class="cart-left-icon-quantity" v-if="item.quantity != 0 && item.quantity != undefined">{{ item.quantity }}</div>
        <div class="business-info">
          <div class="business-info-h">
            <h3>{{ item.businessName }}</h3>
            <div class="business-info-like" :style="getStyle(item)" @click.stop="handleClick(item)">
              <i class="fa fa-star" aria-hidden="true" />
            </div>
          </div>
          <!-- 其他代码 -->
        </div>
      </li>
    </ul>
    <!-- 其他代码 -->
  </div>
</template>

<script setup>
import Footer from '../components/Footer.vue';
import { getSessionStorage } from '../common.js';
import { ref } from "vue";
import { get, post } from '../api';
import { useRouter } from 'vue-router';
import { ElDrawer, ElMessage, ElMessageBox } from 'element-plus';

const drawer = ref(false);
const router = useRouter();
const account = getSessionStorage("account");
const categoryList = ref([]);
const businessList = ref([]);
const keyword = ref('');
const money = ref('');

const getStyle = (item) => {
  return { fontSize: '3.2vw', marginLeft: '1vw', color: item.clicked ? 'red' : 'grey' };
};

const handleClick = (item) => {
  ElMessageBox.confirm(
    '你确定关注吗？',
    '确认操作',
    {
      confirmButtonText: '确定',
      cancelButtonText: '取消',
      type: 'warning'
    }
  ).then(() => {
    if (!item.clicked) {
      item.clicked = true;
      IncrementReadCount(item);
    } else {
      item.clicked = false;
      incrementReadCount(item);
    }
  }).catch(() => {
    // 取消操作
  });
};

const IncrementReadCount = (item) => {
  const requestData = { businessId: item.businessId, accountId: account.accountId };
  post('/AccountBusinessHandler/Statu', requestData, false)
    .then((response) => { })
    .catch(error => { console.error('更新浏览量失败', error); });
};

const incrementReadCount = (item) => {
  const requestData = { businessId: item.businessId, accountId: account.accountId };
  post('/AccountBusinessHandler/statu', requestData, false)
    .then((response) => { })
    .catch(error => { console.error('更新浏览量失败', error); });
};

const init = () => {
  let url = "/CategoryHandler/get";
  get(url).then(response => {
    categoryList.value = response.data.resultdata;
  }).catch(e => {
    console.log(e);
  });

  let business_url = "/BusinessHandler/listByCategoryId?categoryId=" + 0;
  get(business_url).then(response => {
    businessList.value = response.data.resultdata;
  }).catch(e => {
    console.log(e);
  });
};
init();

const search = () => {
  const keyword = document.getElementById('searchInput').value;
  let s_url = "/BusinessHandler/search?keyword=" + keyword;
  get(s_url).then(response => {
    businessList.value = response.data.resultdata;
  }).catch(e => {
    console.log(e);
  });
};

const toBusinessList = (id) => {
  router.push({ path: '/businessList', query: { categoryId: id } });
};

const toVip = () => {
  let url = "/OrdersHandler/sum?accountId=" + account.accountId;
  get(url).then(response => {
    money.value = response.data.resultdata;
    if (money.value > 100) {
      ElMessage({ message: '开通会员成功', type: 'success' });
    } else {
      ElMessage({ message: '开通会员失败', type: 'success' });
    }
  }).catch(e => {
    console.log(e);
  });
};

const toSvip = () => {
  let url = "/OrdersHandler/sum?accountId=" + account.accountId;
  get(url).then(response => {
    money.value = response.data.resultdata;
    if (money.value > 500) {
      ElMessage({ message: '开通超级会员成功', type: 'success' });
    } else {
      ElMessage({ message: '订单金额不足,无法开通', type: 'error' });
    }
  }).catch(e => {
    console.log(e);
  });
};

<style scoped>
/* 保持原有样式 */
</style>

### 解释
1. **引入 `ElMessageBox`**：在 `<script setup>` 中引入 `ElMessageBox`。
2. **修改 `handleClick` 方法**：在 `handleClick` 方法中调用 `ElMessageBox.confirm` 来显示确认对话框。如果用户点击“确定”，则执行收藏或取消收藏的操作；如果用户点击“取消”，则不进行任何操作。

这样，当用户点击收藏按钮时，会弹出一个确认对话框，询问用户是否确定关注。
