一.CUD
什么是cud
CUD 是指增加(Create)、更新(Update)和删除(Delete)操作，是对于数据的基本操作。CUD 是一种常见的数据库操作术语，在许多应用和系统中都会涉及到。
- Create（增加）: Create 操作用于向数据库中添加新的数据记录。根据数据模型的定义，创建新的数据记录可以添加到数据库的表中，以便后续的数据操作和查询。
- Update（更新）: Update 操作用于修改数据库中已有的数据记录。可以通过指定某个准确的标识符（如主键）来定位并更新特定的数据记录。通过 Update 操作，可以修改数据记录中的一个或多个字段的值，从而实现数据的更新。
- Delete（删除）: Delete 操作用于从数据库中删除指定的数据记录。根据指定的标识符（如主键），可以删除特定的数据记录。通过 Delete 操作，可以从数据库中永久地移除不再需要的数据。
CUD 是基本的数据操作，也是实现数据的增删改功能的核心。这些操作在数据库系统中非常重要，并且被广泛应用于各种应用程序和系统中，包括网站、移动应用程序、企业软件等。通过使用 CUD，可以有效地管理和维护数据库中的数据。
编写代码
配置数据访问的地址
/** * 对后台请求的地址的封装，URL格式如下： * 模块名_实体名_操作 */ export default { 'SERVER': 'http://localhost:8080/ssm/', //服务器 'SYSTEM_USER_DOLOGIN': 'user/userLogin', //登陆 'SYSTEM_USER_DOREG': 'userAction.action', //注册 'SYSTEM_MENUS': '/module/queryRootNode', //左侧菜单树 'SYSTEM_BookList': '/book/queryBookPager', //书籍的后端数据请求 'SYSTEM_BookADD': '/book/addBook', //书籍增加的数据请求 'SYSTEM_BookUPD': '/book/editBook', //书籍修改的数据请求 'SYSTEM_BookDEL': '/book/delBook', //书籍删除的数据请求 'getFullPath': k => { //获得请求的完整地址，用于mockjs测试时使用 return this.SERVER + this[k]; } }

二.表单验证
在表单中增加rules，book两个属性
代码如下：
<template> <div class="Book" style="padding: 30px;"> <!-- 输入框搜索 --> <el-form :inline="true" class="demo-form-inline"> <el-form-item label="书籍名称 : "> <el-input v-model="bookname" placeholder="书籍名称"></el-input> </el-form-item> <el-form-item> <el-button type="primary" plain @click="onSubmit">查询</el-button> <el-button type="primary" plain @click="open">新增</el-button> </el-form-item> </el-form> <!-- 书籍的书籍表格 --> <el-table :data="tableData" style="width: 100%"> <el-table-column prop="id" label="书籍ID"></el-table-column> <el-table-column prop="bookname" label="书籍名称"></el-table-column> <el-table-column prop="price" label="书籍价格"></el-table-column> <el-table-column prop="booktype" label="书籍类型"></el-table-column> <el-table-column label="操作"> <template slot-scope="scope"> <el-button size="mini" @click="open(scope.$index, scope.row)">编辑</el-button> <el-button size="mini" type="danger" @click="del(scope.$index, scope.row)">删除</el-button> </template> </el-table-column> </el-table> <!-- 分页 --> <div class="block" style="padding: 20px;"> <el-pagination @size-change="handleSizeChange" @current-change="handleCurrentChange" :current-page="page" background :page-sizes="[10, 20, 30, 40]" :page-size="rows" layout="total, sizes, prev, pager, next, jumper" :total="total"> </el-pagination> </div> <!-- 编辑窗体 --> <el-dialog :title="title" :visible.sync="dialogFormVisible" @close="clear"> <el-form :model="book" :rules="rules" ref="book"> <el-form-item label="书籍编号" :label-width="formLabelWidth" prop="id"> <el-input v-model="book.id" autocomplete="off"></el-input> </el-form-item> <el-form-item label="书籍名称" :label-width="formLabelWidth" prop="bookname"> <el-input v-model="book.bookname" autocomplete="off"></el-input> </el-form-item> <el-form-item label="书籍价格" :label-width="formLabelWidth" prop="price"> <el-input v-model="book.price" autocomplete="off"></el-input> </el-form-item> <el-form-item label="书籍类别" :label-width="formLabelWidth" prop="booktype"> <el-select v-model="book.booktype" placeholder="请选择活动区域"> <el-option v-for="t in types" :label="t.name" :value="t.name" :key="'key_'+t.id"></el-option> </el-select> </el-form-item> </el-form> <div slot="footer" class="dialog-footer"> <el-button @click="dialogFormVisible = false">取 消</el-button> <el-button type="danger" @click="dosub">确 定</el-button> </div> </el-dialog> </div> </template> <script> export default { data() { return { bookname: '', tableData: [], rows: 10, total: 0, page: 1, title: '新增窗体', dialogFormVisible: false, formLabelWidth: '100px', types: [], book: { id: '', bookname: '', price: '', booktype: '' }, rules: { bookname: [{ required: true, message: '请输入书籍名称', trigger: 'blur' }], price: [{ required: true, message: '请输入书籍价格', trigger: 'blur' }], booktype: [{ required: true, message: '请输入书籍类型', trigger: 'blur' }] } } }, methods: { del(idx, row) { this.$confirm('此操作将永久删除id为' + row.id + '的数据, 是否继续?', '提示', { confirmButtonText: '确定', cancelButtonText: '取消', type: 'warning' }).then(() => { let url = this.axios.urls.SYSTEM_BookDEL; this.axios.post(url, { id: row.id }).then(d => { console.log(d); this.$message({ type: 'success', message: '删除成功!' }); this.query({}); this.tableData = d.data.rows; this.total = d.data.total; }).catch(e => { }) }).catch(() => { this.$message({ type: 'info', message: '已取消删除' }); }); }, dosub() { this.$refs['book'].validate((valid) => { if (valid) { let url = this.axios.urls.SYSTEM_BookADD; if (this.title == '编辑窗体') { url = this.axios.urls.SYSTEM_BookUPD; } let params = { id: this.book.id, bookname: this.book.bookname, price: this.book.price, booktype: this.book.booktype } this.axios.post(url, params).then(d => { console.log(d); this.clear(); this.query({}); this.tableData = d.data.rows; this.total = d.data.total; }).catch(e => { }) } else { console.log('error submit!!'); return false; } }); }, clear() { //初始化窗体 this.dialogFormVisible = false; this.title = '新增窗体'; this.book = { id: '', bookname: '', price: '', booktype: '' } }, open(idx, row) { //打开窗体的方法 this.dialogFormVisible = true; if (row) { this.title = '编辑窗体'; this.book.id = row.id; this.book.bookname = row.bookname; this.book.price = row.price; this.book.booktype = row.booktype; } }, handleSizeChange(r) { //当页大小发生变化 let params = { bookname: this.bookname, rows: r, page: this.page } // console.log(params) this.query(params); }, handleCurrentChange(p) { //当前页码大小发生变化 let params = { bookname: this.bookname, rows: this.rows, page: p } this.query(params); }, query(params) { //获取后台请求书籍数据的地址 let url = this.axios.urls.SYSTEM_BookList; this.axios.get(url, { params: params }).then(d => { console.log(url) this.tableData = d.data.rows; this.total = d.data.total; }).catch(e => {}); }, onSubmit() { let params = { bookname: this.bookname } console.log(params) this.query(params); this.bookname = '' } }, created() { this.query({}); this.types = [{ id: 1, name: '玄幻' }, { id: 2, name: '动作' }, { id: 3, name: '爱情' }, { id: 4, name: '伦理' }, { id: 5, name: '霸总' }]; } } </script> <style> </style>
