使用 beforeRouteEnter 在组件 setup 中获取用户数据
beforeRouteEnter(to, from, next) { // 你的逻辑 next(); // 调用 next() 允许导航 }
const UserDetail = { setup(props) {
const userData = ref(null);
return { userData };
},
beforeRouteEnter(to, from, next) {
// 这里的 to.params.userId 是我们在路由中定义的用户 ID 参数
fetchUserData(to.params.userId).then((data) => {
next(vm => { vm.userData.value = data; });
});
} };
