vue3、ts、vue-cli、vue页面。beforeRouteEnter功能调用，并调用vue页面内的变量和函数

<script lang="ts">
import { defineComponent, ComponentPublicInstance } from 'vue';

interface IInstance extends ComponentPublicInstance {
  setPathFrom(from: string): void;
}

export default defineComponent({
  beforeRouteEnter(to, from, next) {
    next((vm) => {
      const instance = vm as IInstance;
      console.log('instance = ', instance.wineDetailData);
        instance.wineDetailData.countInterval = 0;  //变量调用
        instance.getUserInfo();   // 函数调用
    });
  },
});
</script>


<script lang="ts" setup>
import { reactive } from 'vue';
interface typeData{
    countInterval:number;
}
const wineDetailData = reactive<typeData>({
  countInterval: 0
});
const getUserInfo=()=>{
    return ''
}

// 暴露变量和方法给beforeRouteEnter调用
defineExpose({ wineDetailData, getUserInfo });
</script>
