前端创建页面的开发一

创建一个路由

  {path: "/add/question",name: "创建题目",component: AddQuestionView,meta: {access: ACCESS_ENUM.USER,},},

用acro design写

};
</script><style scoped>
#manageQuestionView {
}
</style>

最終效果

题目更新页面的开发

写一个动态路由

携带参数的那种

const router = useRouter();const doUpdate = (question: Question) => {router.push({path: "/update/question",query: {id: question.id,},});
};

修改路由

  {path: "/update/question",name: "更新题目",component: AddQuestionView,meta: {access: ACCESS_ENUM.USER,hideInMenu: true,},},

页码更新细节

我们的管理题目页面不能分页

我们先处理菜单项的权限控制和权限隐藏

在这里改

在组件里面定义属性

属性绑定一个函数

const onPageChange = (page: number) => {searchParams.value = {...searchParams.value,current: page,};
};

可以参考聚合搜索项目状态改变和url状态同步

当我们的属性改变了

就会触发loadData函数

当分页页号改变时 触发@page-change事件 通过改变searchParams的数值

并且通过watchEffect监听searchParams的改变

然后执行loadData重新加载速度

实现页号变化时触发数据的重新加载

然后

/*** 监听 searchParams 变量，改变时触发页面的重新加载*/
watchEffect(() => {loadData();
});

题目列表搜索页

代码
