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="区域二" value="beijing"></el-option>

                </el-select>

            </el-form-item>

            <el-form-item label="活动时间">

                <el-col :span="11">

                <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-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-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">

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&amp;useUnicode=true&amp;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
