vue3 路由跳转空白，刷新页面不会空白
原因是，没有给router-view动态添加key，key根据路径+随机数即可
<template>
<div class="app-main-box">
<router-view :key="key"/>
</div>
</template>
<script setup lang="ts">
import { computed } from '@vue/runtime-core';
import { useRoute } from 'vue-router';
const route = useRoute();
const key = computed(() => {
return route.path + Math.random();
});
</script>
