44 前端实现前端使用vue框架进行开发主要实现了用户管理、课程管理、学生管理、教师管理、作业管理、考试管理等功能。用户管理模块的前端代码如下：

<template>
  <div class="user">
    <el-card>
      <h3 slot="header">用户管理</h3>
      <el-input v-model="searchText" placeholder="请输入关键字搜索" class="search-input" clearable></el-input>
      <el-table :data="userList" stripe>
        <el-table-column prop="id" label="用户ID" width="100"></el-table-column>
        <el-table-column prop="username" label="用户名" width="120"></el-table-column>
        <el-table-column prop="role" label="角色" width="80"></el-table-column>
        <el-table-column label="操作" width="120">
          <template slot-scope="scope">
            <el-button type="primary" size="small" @click="editUser(scope.row)">编辑</el-button>
            <el-button type="danger" size="small" @click="deleteUser(scope.row)">删除</el-button>
          </template>
        </el-table-column>
      </el-table>
      <el-pagination
        class="pagination"
        :current-page="currentPage"
        :page-size="pageSize"
        layout="total, prev, pager, next"
        :total="total"
        @current-change="handleCurrentChange"
      ></el-pagination>
      <el-dialog :visible.sync="dialogVisible" title="编辑用户" width="40%">
        <el-form :model="editForm" :rules="rules" ref="editForm" label-width="100px">
          <el-form-item label="用户名" prop="username">
            <el-input v-model="editForm.username" disabled></el-input>
          </el-form-item>
          <el-form-item label="密码" prop="password">
            <el-input type="password" v-model="editForm.password" autocomplete="off"></el-input>
          </el-form-item>
          <el-form-item label="角色" prop="role">
            <el-radio-group v-model="editForm.role">

            </el-radio-group>
          </el-form-item>
        </el-form>
        <div slot="footer" class="dialog-footer">
          <el-button @click="dialogVisible = false">取 消</el-button>
          <el-button type="primary" @click="submitForm('editForm')">确 定</el-button>
        </div>
      </el-dialog>
