一.增删改查

1.样式准备

<template><div class="books" style="padding: 20px;"><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-form-item><el-form-item><el-button type="primary" @click="onSubmit">查询</el-button><el-button type="primary" @click="open">增加</el-button></el-form-item></el-form><el-table :data="tableData" stripe style="width: 100%"><el-table-column prop="id" label="书籍编号" width="180"></el-table-column><el-table-column prop="bookname" label="书籍名称" width="180"></el-table-column><el-table-column prop="price" label="价格"></el-table-column><el-table-column prop="booktype" label="书籍类别"></el-table-column></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><span class="demonstration">完整功能</span><el-pagination @size-change="handleSizeChange" @current-change="handleCurrentChange" :current-page="page":page-sizes="[10, 20, 30, 40]" :page-size="rows" layout="total, sizes, prev, pager, next, jumper":total="total"></el-pagination><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"><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="书籍类型" :label-width="formLabelWidth" prop="booktype"><el-select v-model="book.booktype" placeholder="请选择书籍类型"><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="primary" @click="dosuib">确 定</el-button></div></el-dialog></div></template>

2.增加

为了代码的简洁性封装了一个clear的方法

clear() {this.dialogFormVisible = false;this.book = {id: '',bookname: '',price: '',booktype: ''}

后面会使用到

dosuib() {this.$refs['book'].validate((valid) => {if (valid) {let url = this.axios.urls.BOOK_ADD;if (this.title == '编辑窗体') {let	url = this.axios.urls.BOOK_UPD;}let params = {id: this.book.id,bookname: this.book.bookname,price: this.book.price,booktype: this.book.booktype};this.axios.post(url, params).then(r => {console.log(r)this.clear();this.query({});}).catch(e => {})} else {console.log('error submit!!');return false;}});},clear() {this.dialogFormVisible = false;this.book = {id: '',bookname: '',price: '',booktype: ''}this.title = '新增窗体';},

3.删除

del(idx, row) {this.$confirm('此操作将删除该记录, 是否继续?', '提示', {confirmButtonText: '确定',cancelButtonText: '取消',type: 'warning'}).then(() => {let url = this.axios.urls.BOOK_DEL;this.axios.post(url, {id:row.id}).then(r => {console.log(r);this.$message({type: 'success',message: '删除成功!'});this.query({});}).catch(e => {})}).catch(() => {this.$message({type: 'info',message: '已取消删除'});});},

4.修改

open(idx, row) {this.dialogFormVisible = true;if (row) {this.title = '编辑窗体';this.book.bookname = row.bookname;this.book.price = row.price;this.book.booktype = row.booktype;this.book.id = row.id;}},

5.查询

query(params) {let url = this.axios.urls.BOOK_LIST;this.axios.get(url, {params: params}).then(r => {console.log(r)this.tableData = r.data.rows;this.total = r.data.total;}).catch(e => {})},
onSubmit() {let params = {bookname: this.bookname}this.query(params);},handleSizeChange(r) {let params = {bookname: this.bookname,rows: r,page: this.page}this.query(params);},handleCurrentChange(p) {let params = {bookname: this.bookname,rows: this.rows,page: p}this.query(params);}},

#所有代码

url

/*** 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/', //服务器'SYSTEM_USER_DOLOGIN': '/user/userLogin', //登陆'SYSTEM_USER_DOREG': '/user/userRegister', //注册'SYSTEM_USER_MENUS': '/module/queryRootNode', //左侧'BOOK_LIST': '/book/queryBookPager', //书籍列表'BOOK_ADD': '/book/addBook', //书籍增加'BOOK_UPD': '/book/editBook', //书籍修改'BOOK_DEL': '/book/delBook', //书籍删除'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

1.在表单中使用验证规则

<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"><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="书籍类型" :label-width="formLabelWidth" prop="booktype"><el-select v-model="book.booktype" placeholder="请选择书籍类型"><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="primary" @click="dosuib">确 定</el-button></div></el-dialog>

2.定义规则

rules: {bookname: [{required: true,message: '请输入书籍名称',trigger: 'blur'},{min: 4,max: 11,message: '长度在 3 到 5 个字符',trigger: 'blur'}],price: [{required: true,message: '请输入书籍名称',trigger: 'blur'}],booktype: [{required: true,message: '请输入书籍名称',trigger: 'blur'}]}}},
