前言
本章内容主要包含：
- 注册界面搭建
- 数据绑定
- 表单校验
- 调用后端接口
一、搭建界面
<script setup>
import { User, Lock } from '@element-plus/icons-vue'
import { ref } from 'vue'
//控制注册与登录表单的显示， 默认显示注册
const isRegister = ref(false)
</script>
<template>
<el-row class="login-page">
<el-col :span="12" class="bg"></el-col>
<el-col :span="6" :offset="3" class="form">
<!-- 注册表单 -->
<el-form ref="registerFormRef" size="large" autocomplete="off" v-if="isRegister">
<el-form-item>
<h1>注册</h1>
</el-form-item>
<el-form-item>
<el-input :prefix-icon="User" placeholder="请输入用户名"></el-input>
</el-form-item>
<el-form-item>
<el-input :prefix-icon="Lock" type="password" placeholder="请输入密码"></el-input>
</el-form-item>
<el-form-item>
<el-input :prefix-icon="Lock" type="password" placeholder="请输入再次密码"></el-input>
</el-form-item>
<!-- 注册按钮 -->
<el-form-item>
<el-button class="button" type="primary" auto-insert-space>
注册
</el-button>
</el-form-item>
<el-form-item class="flex">
<el-link type="info" :underline="false" @click="isRegister = false">
← 返回
</el-link>
</el-form-item>
</el-form>
<!-- 登录表单 -->
<el-form ref="form" size="large" autocomplete="off" v-else>
<el-form-item>
<h1>登录</h1>
</el-form-item>
<el-form-item>
<el-input :prefix-icon="User" placeholder="请输入用户名"></el-input>
</el-form-item>
<el-form-item>
<el-input name="password" :prefix-icon="Lock" type="password" placeholder="请输入密码"></el-input>
</el-form-item>
<el-form-item class="flex">
<div class="flex">
<el-checkbox>记住我</el-checkbox>
<el-link type="primary" :underline="false">忘记密码？</el-link>
</div>
</el-form-item>
<!-- 登录按钮 -->
<el-form-item>
<el-button class="button" type="primary" auto-insert-space>登录</el-button>
</el-form-item>
<el-form-item class="flex">
<el-link type="info" :underline="false" @click="isRegister = true">
注册 →
</el-link>
</el-form-item>
</el-form>
</el-col>
</el-row>
</template>
<style lang="scss" scoped>
/* 样式 */
.login-page {
height: 100vh;
background-color: #fff;
.bg {
background: url('@/assets/logo2.png') no-repeat 60% center / 240px auto,
url('@/assets/login_bg.jpg') no-repeat center / cover;
border-radius: 0 20px 20px 0;
}
.form {
display: flex;
flex-direction: column;
justify-content: center;
user-select: none;
.title {
margin: 0 auto;
}
.button {
width: 100%;
}
.flex {
width: 100%;
display: flex;
justify-content: space-between;
}
}
}
</style>
二、数据绑定
1.定义响应数据
//用于注册的数据模型
const registerData = ref({
username: '',
password: '',
rePassword: ''
})
2.绑定数据
<!-- 注册表单 -->
<el-form ref="form" size="large" autocomplete="off" v-if="isRegister" v-model="registerData">
<el-form-item>
<h1>注册</h1>
</el-form-item>
<el-form-item>
<el-input :prefix-icon="User" placeholder="请输入用户名" v-model="registerData.username"></el-input>
</el-form-item>
<el-form-item>
<el-input :prefix-icon="Lock" type="password" placeholder="请输入密码" v-model="registerData.password"></el-input>
</el-form-item>
<el-form-item>
<el-input :prefix-icon="Lock" type="password" placeholder="请输入再次密码" v-model="registerData.rePassword"></el-input>
</el-form-item>
<!-- 注册按钮 -->
<el-form-item>
<el-button class="button" type="primary" auto-insert-space>
注册
</el-button>
</el-form-item>
<el-form-item class="flex">
<el-link type="info" :underline="false" @click="isRegister = false">
← 返回
</el-link>
</el-form-item>
</el-form>
三、数据校验
1. 定义校验规则
//自定义确认密码的校验函数
const rePasswordValid = (rule, value, callback) => {
console.log(value);
if (value == null || value === '') {
callback(new Error('请再次确认密码'))
} else if (value !== registerData.value.password) {
callback(new Error('两次输入密码不一致'))
} else {
callback()
}
}
//用于注册的表单校验模型
const registerDataRules = ref({
username: [
{ required: true, message: '请输入用户名', trigger: 'blur' },
{ min: 5, max: 16, message: '用户名的长度必须为5~16位', trigger: 'blur' }
],
password: [
{ required: true, message: '请输入密码', trigger: 'blur' },
{ min: 5, max: 16, message: '密码长度必须为5~16位', trigger: 'blur' }
],
rePassword: [
{ validator: rePasswordValid, trigger: 'blur' }
]
})
2. 表单校验
Form 组件提供了表单验证的功能，只需为 rules 属性传入约定的验证规则，并将 form-Item 的 prop 属性设置为需要验证的特殊键值即可。
<!-- 注册表单 -->
<el-form ref="registerFormRef" size="large" autocomplete="off" v-if="isRegister" :model="registerData" :rules="registerDataRules">
<el-form-item>
<h1>注册</h1>
</el-form-item>
<el-form-item prop="username">
<el-input :prefix-icon="User" placeholder="请输入用户名" v-model="registerData.username"></el-input>
</el-form-item>
<el-form-item prop="password">
<el-input :prefix-icon="Lock" type="password" placeholder="请输入密码" v-model="registerData.password"></el-input>
</el-form-item>
<el-form-item prop="rePassword">
<el-input :prefix-icon="Lock" type="password" placeholder="请输入再次密码" v-model="registerData.rePassword"></el-input>
</el-form-item>
<!-- 注册按钮 -->
<el-form-item>
<el-button class="button" type="primary" auto-insert-space>
注册
</el-button>
</el-form-item>
<el-form-item class="flex">
<el-link type="info" :underline="false" @click="isRegister = false">
← 返回
</el-link>
</el-form-item>
</el-form>
3. 展示
四、注册接口调用
1. user.js
import request from '@/utils/request.js'
export const registerService = (registerData)=>{
var params = new URLSearchParams()
for (let key in registerData) {
params.append(key, registerData[key])
}
return request.post('/user/register', params)
}
2. Login.vue
import { ElMessage } from 'element-plus'
import { User, Lock } from '@element-plus/icons-vue'
import { ref } from 'vue'
import { registerService } from '@/api/user.js'
//注册按钮点击事件
const registerFormRef = ref(null)
const registerUser =async () => {
let result =await registerService(registerData.value)
let message = result.message
if (result.code == 0) {
ElMessage.success(message ? message : '注册成功!')
} else {
ElMessage.error(message ? message : '注册失败!')
}
}
const register = () => {
if (!registerFormRef) return
const valid = registerFormRef.value.validate((valid, fields) => {
if (valid) {
registerUser();
}
})
}
