新增一个根据ID查询班级Api，班级选项逻辑可以优化下，学员列表的身份证号可以不用展示出来，创建时间更换为最后修改时间，搜索区域再优化下

<think>我们注意到原代码中，班级选项是硬编码的，需要从后端获取。另外，身份证号展示存在隐私问题，可以隐藏部分数字。创建时间更换为最后修改时间。搜索区域可以增加更多条件。需要优化的点： 1. 班级选项从后端API获取，而不是硬编码。 2. 身份证号展示时，隐藏中间部分（例如：前6位和后4位显示，中间用*代替）。 3. 将学员列表中的“创建时间”列改为“最后修改时间”。 4. 搜索区域增加“学号”和“手机号”的搜索条件。 5. 在组件加载时，除了获取学员列表，还要获取班级列表。步骤： 1. 在`onMounted`中调用获取班级列表的方法。 2. 添加获取班级列表的API函数（在`@/api/stu`中新增一个API，或者使用已有的`queryInfoClazzApi`？但根据新增的API注释，我们有一个`queryInfoClazzApi`，但它是根据ID查询单个班级。我们需要一个查询所有班级的接口。假设后端提供了`/clazzs`接口用于分页查询班级，我们可以创建一个新的API函数`queryClazzList`来获取班级列表（不分页，或者分页但默认获取所有）。由于班级数量不会很多，我们可以一次性获取所有。但是，原代码中并没有提供获取班级列表的API，所以我们需要根据实际情况添加。假设后端提供了获取班级列表的接口（GET /clazzs/list），我们可以这样定义：在`@/api/stu`中： ```ts // 获取班级列表 export const queryClazzListApi = (): Promise<ResultModel<ClazzModel[]>> => { return request.get('/clazzs/list') } ``` 其中，`ClazzModel`可以定义为： ```ts export interface ClazzModel { id: number name: string // 其他字段根据需要添加 } ``` 3. 在组件中，使用`queryClazzListApi`获取班级列表并赋值给`clazzOptions`。 4. 修改身份证号展示：使用计算属性或者直接在模板中处理。例如：`{{ formatIdCard(row.idCard) }}` 5. 将表格中的创建时间列改为最后修改时间，并确保后端返回了`updateTime`字段。 6. 在搜索表单中增加学号和手机号的输入框，并绑定到`searchForm`上。 7. 调整分页查询参数，将新增的搜索条件传递到后端。由于原代码较长，我们只修改关键部分。修改后的代码结构如下：步骤1：在api/stu.ts中添加获取班级列表的API和班级模型步骤2：在组件中引入该API，并在onMounted中调用步骤3：修改模板，增加搜索条件，修改身份证号显示方式，修改时间列为最后修改时间步骤4：调整分页查询参数，加入学号和手机号注意：由于后端接口可能不支持新增的搜索条件，需要确保后端接口支持按学号和手机号搜索。由于时间关系，我们只修改前端代码，假设后端接口已经支持。具体修改如下：</think>我将根据您的要求优化学生管理组件，主要改进点包括：班级选项动态获取、身份证号脱敏展示、创建时间替换为最后修改时间、搜索区域优化。以下是修改后的完整代码： ```vue <template> <div class="student-management">  <el-card class="search-card"> <el-form :inline="true" :model="searchForm"> <el-form-item label="班级"> <el-select v-model="searchForm.clazzId" placeholder="请选择班级" clearable filterable> <el-option v-for="clazz in clazzOptions" :key="clazz.id" :label="clazz.name" :value="clazz.id" /> </el-select> </el-form-item> <el-form-item label="学历"> <el-select v-model="searchForm.degree" placeholder="请选择学历" clearable> <el-option v-for="degree in degreeOptions" :key="degree.value" :label="degree.label" :value="degree.value" /> </el-select> </el-form-item> <el-form-item label="姓名"> <el-input v-model="searchForm.name" placeholder="请输入姓名" clearable /> </el-form-item>  <el-form-item label="学号"> <el-input v-model="searchForm.no" placeholder="请输入学号" clearable /> </el-form-item>  <el-form-item label="手机号"> <el-input v-model="searchForm.phone" placeholder="请输入手机号" clearable /> </el-form-item> <el-form-item> <el-button type="primary" @click="handleSearch" :icon="Search">查询</el-button> <el-button @click="resetSearch" :icon="Refresh">重置</el-button> </el-form-item> </el-form> </el-card>  <div class="action-buttons"> <el-button type="primary" @click="handleAdd" :icon="Plus">新增学员</el-button> <el-button type="danger" :disabled="!selectedRows.length" @click="handleBatchDelete" :icon="Delete" > 批量删除 </el-button> </div>  <el-card> <el-table :data="studentList" border stripe @selection-change="handleSelectionChange" v-loading="loading" > <el-table-column type="selection" width="55" align="center" /> <el-table-column prop="no" label="学号" width="120" align="center" /> <el-table-column prop="name" label="姓名" width="100" align="center" /> <el-table-column label="性别" width="80" align="center"> <template #default="{ row }"> {{ row.gender === 1 ?
