使用Vue3开发学生管理系统模板1

环境搭建

通过解压之前《Vue3开发后台管理系统模板》的代码，我们能够得到用户增删改查的页面，我们基于用户增删改查的页面做进一步的优化。

创建学生增删改查页面

第一步：复制用户增删改查页面，重命名为StudentCRUD.vue

<script setup>
import {FilterMatchMode} from 'primevue/api';
import {ref, onBeforeMount} from 'vue';
import {useToast} from 'primevue/usetoast';
import users from "@/assets/data/user.json"// 用户
const user = ref({id: 0,name: "",age: 0,
})
const toast = useToast();const userDialog = ref(false); // 用户弹窗是否显示
const deleteUserDialog = ref(false); // 确认删除用户弹窗是否显示
const deleteUsersDialog = ref(false); // 批量删除用户弹窗是否显示
const selectedUsers = ref(null);
const dt = ref(null);
const filters = ref({});
const submitted = ref(false);onBeforeMount(() => {initFilters();
});/*** 打开新增用户的弹窗*/
function openNew() {user.value = {id: 0,name: "",age: 0,};submitted.value = false;userDialog.value = true;
}/*** 新增用户*/
function addUser() {console.log("新增用户：", user.value)userDialog.value = false
}const hideDialog = () => {userDialog.value = false;submitted.value = false;
};const editUser = (editUser) => {user.value = {...editUser};console.log(user);userDialog.value = true;
};/*** 确认删除用户* @param editUser 要删除的用户信息*/
const confirmDeleteUser = (editUser) => {user.value = editUser;deleteUserDialog.value = true;
};/*** 删除用户*/
const deleteUser = () => {users = users.filter((val) => val.id !== user.value.id);deleteUserDialog.value = false;user.value = {id: 0,name: "",age: 0,};toast.add({severity: 'success', summary: '成功', detail: '删除用户', life: 3000});
};const exportCSV = () => {dt.value.exportCSV();
};const confirmDeleteSelected = () => {deleteUsersDialog.value = true;
};/*** 删除选中的用户*/
const deleteSelectedUsers = () => {users = users.filter((val) => !selectedUsers.value.includes(val));deleteUsersDialog.value = false;selectedUsers.value = null;toast.add({severity: 'success', summary: '成功', detail: '删除用户', life: 3000});
};/*** 初始化过滤器*/
const initFilters = () => {filters.value = {global: {value: null, matchMode: FilterMatchMode.CONTAINS}};
};
</script><template><div class="grid"><div class="col-12"><div class="card"><!--消息提示--><Toast/><!--顶部工具栏--><Toolbar class="mb-4"><!--左侧--><template v-slot:start><div class="my-2"><Button label="新增" icon="pi pi-plus" class="p-button-success mr-2" @click="openNew"/><Button label="删除" icon="pi pi-trash" class="p-button-danger" @click="confirmDeleteSelected":disabled="!selectedUsers || !selectedUsers.length"/></div></template><!--右侧--><template v-slot:end><FileUpload mode="basic" accept="image/*" :maxFileSize="1000000" label="Import" chooseLabel="导入"class="mr-2 inline-block"/><Button label="导出" icon="pi pi-upload" class="p-button-help" @click="exportCSV($event)"/></template></Toolbar><!--数据表格--><DataTableref="dt":value="users"v-model:selection="selectedUsers"dataKey="id":paginator="true":rows="10":filters="filters"paginatorTemplate="FirstPageLink PrevPageLink PageLinks NextPageLink LastPageLink CurrentPageReport RowsPerPageDropdown":rowsPerPageOptions="[5, 10, 25]"currentPageReportTemplate="Showing {first} to {last} of {totalRecords} products"responsiveLayout="scroll"><!--表头--><template #header><div class="flex flex-column md:flex-row md:justify-content-between md:align-items-center"><h5 class="m-0">用户管理</h5><span class="block mt-2 md:mt-0 p-input-icon-left"><i class="pi pi-search"/><InputText v-model="filters['global'].value" placeholder="搜索..."/></span></div></template><!--内容--><Column selectionMode="multiple" headerStyle="width: 3rem"></Column><Column field="name" header="姓名" :sortable="true" headerStyle="min-width:10rem;"></Column><Column field="age" header="年龄" :sortable="true" headerStyle="min-width:8rem;"></Column><Column headerStyle="min-width:10rem;"><template #body="slotProps"><Button icon="pi pi-pencil" class="p-button-rounded p-button-success mr-2"@click="editUser(slotProps.data)"/><Button icon="pi pi-trash" class="p-button-rounded p-button-warning mt-2"@click="confirmDeleteUser(slotProps.data)"/></template></Column></DataTable><!--新增弹窗--><Dialog v-model:visible="userDialog":style="{ width: '450px' }"header="新增用户":modal="true"class="p-fluid"><div class="field"><label for="name">姓名</label><InputText id="name" v-model.trim="user.name" required="true" autofocus:class="{ 'p-invalid': submitted && !user.name }"/><small class="p-invalid" v-if="submitted && !user.name">姓名不能为空</small></div><div class="field"><label for="name">年龄</label><InputText id="name" v-model.number="user.age" required="true" autofocus:class="{ 'p-invalid': submitted && !user.age }"/><small class="p-invalid" v-if="submitted && !user.age">年龄不能为空</small></div><template #footer><Button label="取消" icon="pi pi-times" class="p-button-text" @click="hideDialog"/><Button label="保存" icon="pi pi-check" class="p-button-text" @click="addUser"/></template></Dialog><!--确认删除弹窗--><Dialog v-model:visible="deleteUserDialog" :style="{ width: '450px' }" header="Confirm" :modal="true"><div class="flex align-items-center justify-content-center"><i class="pi pi-exclamation-triangle mr-3" style="font-size: 2rem"/><span v-if="user">您确认要删除 <b>{{ user.name }}</b>吗？</span></div><template #footer><Button label="取消" icon="pi pi-times" class="p-button-text" @click="deleteUserDialog = false"/><Button label="确认" icon="pi pi-check" class="p-button-text" @click="deleteUser"/></template></Dialog><!--批量删除确认弹窗--><Dialog v-model:visible="deleteUsersDialog" :style="{ width: '450px' }" header="请确认" :modal="true"><div class="flex align-items-center justify-content-center"><i class="pi pi-exclamation-triangle mr-3" style="font-size: 2rem"/><span v-if="user">删除后无法撤销，您确定要删除吗？</span></div><template #footer><Button label="取消" icon="pi pi-times" class="p-button-text" @click="deleteUsersDialog = false"/><Button label="确认" icon="pi pi-check" class="p-button-text" @click="deleteSelectedUsers"/></template></Dialog></div></div></div>
</template>

第二步：在router/index.js中，配置学生增删改查的路由

{path: '/pages/crud/student',name: '/pages/crud/student',component: () => import('@/pages/crud/StudentCRUD.vue')
}

第三步：在AppMenu.vue中，添加学生增删改查的跳转链接

{label: '学生增删改查', icon: 'pi pi-fw pi-home', to: '/pages/crud/student'},

效果图如下：这样我们就有了一个学生增删改查的基本页面

]

渲染学生信息

第一步：导入学生JSON数据

import students from "@/assets/data/students.json"

第二步：传入DataTable数据表格

:value="students"

第三步：编辑要显示的字段

<DataTableref="dt":value="students"v-model:selection="selectedUsers"dataKey="id":paginator="true":rows="10":filters="filters"paginatorTemplate="FirstPageLink PrevPageLink PageLinks NextPageLink LastPageLink CurrentPageReport RowsPerPageDropdown":rowsPerPageOptions="[5, 10, 25]"currentPageReportTemplate="Showing {first} to {last} of {totalRecords} products"responsiveLayout="scroll"><!--表头--><template #header><div class="flex flex-column md:flex-row md:justify-content-between md:align-items-center"><h5 class="m-0">学生管理</h5><span class="block mt-2 md:mt-0 p-input-icon-left"><i class="pi pi-search"/><InputText v-model="filters['global'].value" placeholder="搜索..."/></span></div></template><!--内容--><Column selectionMode="multiple" headerStyle="width: 3rem"></Column><Column field="sclass_name" header="班级" :sortable="true" headerStyle="min-width:10rem;"></Column><Column field="name" header="姓名" :sortable="true" headerStyle="min-width:10rem;"></Column><Column field="age" header="年龄" :sortable="true" headerStyle="min-width:8rem;"></Column><Column field="gender" header="性别" :sortable="true" headerStyle="min-width:8rem;"></Column><Column field="phone" header="手机" :sortable="true" headerStyle="min-width:8rem;"></Column><Column field="master_name" header="班主任" :sortable="true" headerStyle="min-width:8rem;"></Column><Column field="master_phone" header="班主任电话" :sortable="true" headerStyle="min-width:8rem;"></Column><Column field="home_name" header="家长" :sortable="true" headerStyle="min-width:8rem;"></Column><Column field="home_phone" header="家长电话" :sortable="true" headerStyle="min-width:8rem;"></Column><Column headerStyle="min-width:10rem;"><template #body="slotProps"><Button icon="pi pi-pencil" class="p-button-rounded p-button-success mr-2"@click="editUser(slotProps.data)"/><Button icon="pi pi-trash" class="p-button-rounded p-button-warning mt-2"@click="confirmDeleteUser(slotProps.data)"/></template></Column></DataTable>

const dt = ref(null);
const filters = ref({});
const submitted = ref(false);onBeforeMount(() => {initFilters();
