ElementUI表单
Form表单，每一个表单域是由一个form-item组件构成的，表单域中可以放置各种类型的表单控键，有input、switch、checkbox
表单的绑定form
内容分别是form内的对象
<template>
<div>
<el-form ref="form" :model="form" label-width="80px">
<el-form-item label="活动名称">
<el-input v-model="form.name"></el-input>
</el-form-item>
<el-form-item label="活动区域">
<el-select v-model="form.region" placeholder="请选择活动区域">
<el-option label="区域一" value="shanghai"></el-option>
<el-option label="区域二" value="beijing"></el-option>
</el-select>
</el-form-item>
<el-form-item label="活动时间">
<el-col :span="11">
<el-date-picker type="date" placeholder="选择日期" v-model="form.date1" style="width: 100%;"></el-date-picker>
</el-col>
<el-col class="line" :span="2">-</el-col>
<el-col :span="11">
<el-time-picker placeholder="选择时间" v-model="form.date2" style="width: 100%;"></el-time-picker>
</el-col>
</el-form-item>
<el-form-item label="即时配送">
<el-switch v-model="form.delivery"></el-switch>
</el-form-item>
<el-form-item label="活动性质">
<el-checkbox-group v-model="form.type">
<el-checkbox label="美食/餐厅线上活动" name="type"></el-checkbox>
<el-checkbox label="地推活动" name="type"></el-checkbox>
<el-checkbox label="线下主题活动" name="type"></el-checkbox>
<el-checkbox label="单纯品牌曝光" name="type"></el-checkbox>
</el-checkbox-group>
</el-form-item>
<el-form-item label="特殊资源">
<el-radio-group v-model="form.resource">
<el-radio label="线上品牌商赞助"></el-radio>
<el-radio label="线下场地免费"></el-radio>
</el-radio-group>
</el-form-item>
<el-form-item label="活动形式">
<el-input type="textarea" v-model="form.desc"></el-input>
</el-form-item>
<el-form-item>
<el-button type="primary" @click="onSubmit">立即创建</el-button>
<el-button>取消</el-button>
</el-form-item>
</el-form>
</div>
</template>
<script>
export default {
data() {
return {
form: {
name: '',
region: '',
date1: '',
date2: '',
delivery: false,
type: [],
resource: '',
desc: ''
}
}
},
methods: {
onSubmit() {
console.log('submit!');
}
}
}
</script>
<style scoped>
</style>
表单的数据校验：
表单要绑定rules
内容在绑定rules里面的内容
<el-form :model="ruleForm" :rules="rules" ref="ruleForm" label-width="100px" class="demo-ruleForm">
<el-form-item label="活动名称" prop="name">
<el-input v-model="ruleForm.name"></el-input>
</el-form-item>
<el-form-item label="活动区域" prop="region">
<el-select v-model="ruleForm.region" placeholder="请选择活动区域">
<el-option label="区域一" value="shanghai"></el-option>
<el-option label="区域二" value="beijing"></el-option>
</el-select>
</el-form-item>
<el-form-item label="活动时间" required>
<el-col :span="11">
<el-form-item prop="date1">
<el-date-picker type="date" placeholder="选择日期" v-model="ruleForm.date1" style="width: 100%;"></el-date-picker>
</el-form-item>
</el-col>
<el-col class="line" :span="2">-</el-col>
<el-col :span="11">
<el-form-item prop="date2">
<el-time-picker placeholder="选择时间" v-model="ruleForm.date2" style="width: 100%;"></el-time-picker>
</el-form-item>
</el-col>
</el-form-item>

</el-checkbox-group>
</el-form-item>
<el-form-item label="特殊资源" prop="resource">
<el-radio-group v-model="ruleForm.resource">
<el-radio label="线上品牌商赞助"></el-radio>

</el-form-item>
</el-form>
<script>
export default {
data() {
return {
ruleForm: {
name: '',
region: '',
date1: '',
date2: '',
delivery: false,
type: [],
resource: '',
desc: ''
},
rules: {

{ required: true, message: '请输入活动名称', trigger: 'blur' },
{ min: 3, max: 5, message: '长度在 3 到 5 个字符', trigger: 'blur' }
],
region: [
{ required: true, message: '请选择活动区域', trigger: 'change' }
],
date1: [
{ type: 'date', required: true, message: '请选择日期', trigger: 'change' }
],
date2: [
{ type: 'date', required: true, message: '请选择时间', trigger: 'change' }
],
type: [
{ type: 'array', required: true, message: '请至少选择一个活动性质', trigger: 'change' }

this.$refs[formName].validate((valid) => {
if (valid) {
alert('submit!');

return false;
}
});
},
resetForm(formName) {
this.$refs[formName].resetFields();
}
}
}
</script>
自定义数据校验
案例
CRUD
后端的代码：
1.数据库建表
2.pom.xml添加mybatisplus的相关依赖
<!-- mybatisPlus-->
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-boot-starter</artifactId>
<version>3.3.2</version>
</dependency>
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-generator</artifactId>
<version>3.3.2</version>
</dependency>
<dependency>
<groupId>org.apache.velocity</groupId>
<artifactId>velocity</artifactId>
<version>1.7</version>
</dependency>
代码生成器
3.通过mybatis plus generator自动生成后端代码
package com.southwind.springboot;
import com.baomidou.mybatisplus.annotation.DbType;
import com.baomidou.mybatisplus.generator.AutoGenerator;
import com.baomidou.mybatisplus.generator.config.DataSourceConfig;
import com.baomidou.mybatisplus.generator.config.GlobalConfig;
import com.baomidou.mybatisplus.generator.config.PackageConfig;
import com.baomidou.mybatisplus.generator.config.StrategyConfig;
import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;
public class Main {
public static void main(String[] args) {
//创建对象
AutoGenerator autoGenerator = new AutoGenerator();
//数据源
DataSourceConfig dataSourceConfig= new DataSourceConfig();
dataSourceConfig.setDbType(DbType.MYSQL);
dataSourceConfig.setDriverName("com.mysql.jdbc.Driver");
dataSourceConfig.setUrl("jdbc:mysql://localhost:3306/text?serverTimezone=UTC&useUnicode=true&characterEncoding=utf8");
dataSourceConfig.setUsername("root");
dataSourceConfig.setPassword("123456");
autoGenerator.setDataSource(dataSourceConfig);
//全局配置
GlobalConfig globalConfig=new GlobalConfig();
globalConfig.setOutputDir(System.getProperty("user.dir")+"/src/main/java");
globalConfig.setAuthor("张三");
globalConfig.setOpen(false);
//去掉Service
globalConfig.setServiceName("%sService");
autoGenerator.setGlobalConfig(globalConfig);
//包配置
PackageConfig packageConfig =new PackageConfig();
packageConfig.setParent("com.southwind");
packageConfig.setEntity("entity");
packageConfig.setMapper("mapper");
packageConfig.setService("service");
packageConfig.setServiceImpl("service.impl");
packageConfig.setController("controller");
//策略配置
StrategyConfig strategyConfig =new StrategyConfig();
strategyConfig.setInclude("peopel");
strategyConfig.setNaming(NamingStrategy.underline_to_camel);
strategyConfig.setColumnNaming(NamingStrategy.underline_to_camel);
strategyConfig.setEntityLombokModel(true);
autoGenerator.setStrategy(strategyConfig);
//启动
autoGenerator.execute();
}
}
4.Controller中添加其他方法
package com.baomidou.controller;
import com.baomidou.entity.People;
import com.baomidou.service.PeopleService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import org.springframework.stereotype.Controller;
import java.util.List;
/**
* <p>
* 前端控制器
* </p>
*
* @author 张三
* @since 2022-04-28
*/
@RestController
@RequestMapping("/people")
public class PeopleController {
@Autowired
private PeopleService peopleService;
@GetMapping("/list")
public List<People> list(){
return this.peopleService.list();
}
@GetMapping("/findbyid/{id}")
public People findById(@RequestParam("id") Integer id){
return this.peopleService.getById(id);
}
@DeleteMapping("/delete/{id}")
public boolean delete(@RequestParam("id")Integer id){
return this.peopleService.removeById(id);
}
@PostMapping("/add/")
public boolean add(@RequestBody People people){
return this.peopleService.save(people);
}
@PutMapping("/update")
public boolean update(@RequestBody People people){
return this.peopleService.updateById(people);
}
}
配置文件：
server:
port: 8080
servlet:
context-path: /
session:
cookie:
max-age: 100
timeout: 100
tomcat:
uri-encoding: utf-8
spring:
datasource:
url: jdbc:mysql://localhost:3306/text?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8
driver-class-name: com.mysql.cj.jdbc.Driver
username: root
password: 123456
mybatis-plus:
configuration:
log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
type-aliases-package: com.baomidou.entity
前段的代码
1.安装axios插件
输入axios然后安装成功
解决跨域
控制类加：
@CrossOrigin
@RestController
@RequestMapping("/people")
flex布局
弹性布局
display：flex
控制下级盒子的位置
- flex-direction:column
- justify-context:center
- align-items:flex-end、center
也能自己控制自己
align-self:flex-end
放到开头：
一般小白：justify-self:flex-start
但是实际是用边距实现：margin：auto
4.flex:1 会占满下局的全部位置
移动端
1.配置vue的环境
2.安装vant ui
cnpm i vant -S
3.安装less
cnpm install less less-loader --save
