vue3使用el-form实现登录、注册功能，且进行表单验证（Element Plus中的el-form）

简介：Element Plus 中的 el-form 是一个表单组件，用于快速构建表单并进行数据校验。它提供了丰富的表单元素和验证规则，使表单开发变得更加简单和高效。可以搭配el-dialog实现当前页面的登录、注册页 ，这两天在vue3中用到了表单登录，特意记录一下，这里没有封装，直接使用的。

效果：

1、登录页面，弹出框表单

<el-dialog v-model="dialogFormVisible" class="poup_box"><el-tabs v-model="activeName" class="demo-tabs" @tab-click="handleClick"><el-tab-pane label="登录" name="login_one"><el-form ref="ruleFormRef" :model="loginForm" :rules="loginRules" class="login_one"><el-form-item label="用户" prop="username" v-if="loginStatus"><el-input clearable v-model="loginForm.username" autocomplete="off" placeholder="请输入用户名" /></el-form-item><el-form-item label="邮箱" prop="email" v-else><el-input v-model="loginForm.email" autocomplete="off" placeholder="请输入邮箱" /></el-form-item><el-form-item label="密码" prop="password"><el-input v-model="loginForm.password" type="password" show-password autocomplete="off"placeholder="请输入密码" /></el-form-item><el-form-item class="forget_item"><div @click="changeEmail"><span v-if="loginStatus">邮箱登录</span><span v-else>用户名登录</span></div></el-form-item><el-form-item class="checks_box"><el-checkbox v-model="checked1" size="large" class="checks_inpt" /><div class="checks_text"><span>我已阅读并同意</span><b @click="changeAgreement">服务条款、</b><b>隐私政策</b></div><div class="userDeal" v-if="userDeal">请阅读并同意协议</div></el-form-item><el-form-item class="login_item"><el-button @click="userLogin(ruleFormRef)" :loading="isLoading"><span v-if="isLoading">登录中......</span><span v-else>登录</span></el-button></el-form-item></el-form></el-tab-pane><el-tab-pane label="注册" name="register_two"><el-form ref="ruleFormRef2" :model="registerForm" :rules="registerRules" class="register_two"><el-form-item label="用户" prop="username"><el-input clearable v-model="registerForm.username" autocomplete="off" placeholder="请输入用户名" /></el-form-item><el-form-item label="邮箱" prop="email"><el-input v-model="registerForm.email" autocomplete="off" placeholder="请输入邮箱" /></el-form-item><el-form-item label="密码" prop="password"><el-input v-model="registerForm.password" type="password" show-password autocomplete="off"placeholder="密码由字母、数字或符号组成" /></el-form-item><el-form-item label="邮箱验证码" prop="smsCode" class="auth_code"><el-input v-model="registerForm.smsCode" autocomplete="off" placeholder="请输入验证码" /><div class="auth_text"><span @click="getAuthCode(ruleFormRef2)" v-if="authCodeNum">获取验证码</span><span class="auth_time" v-else>{{ registerNum }}秒后重发</span></div></el-form-item><el-form-item class="checks_box"><el-checkbox v-model="registerCks" size="large" class="checks_inpt" /><div class="checks_text"><span>我已阅读并同意</span><b @click="changeAgreement">服务条款、</b><b>隐私政策</b></div><div class="userDeal" v-if="registerDeal">请阅读并同意协议</div></el-form-item><el-form-item class="login_item register_item"><el-button @click="registerUser(ruleFormRef2)">注册</el-button></el-form-item></el-form></el-tab-pane></el-tabs></el-dialog>

2、相关参数，多去少补

import { ElMessage } from 'element-plus'
//import { ref,reactive,toRefs,computed } from 'vue';
//import { useStore } from 'vuex';
import { useRouter, useRoute } from 'vue-router';
//const store = useStore();
const router = useRouter();
//const route = useRoute();
//const state = reactive({});
import { reactive, ref, onMounted } from 'vue';
import func from 'vue-temp/vue-editor-bridge';const loginStatus = ref(true);//用户/邮箱
const isLoading = ref(false); //按钮loading  
import type { FormInstance, FormRules } from 'element-plus';
const ruleFormRef = ref<FormInstance>()
const ruleFormRef2 = ref<FormInstance>()
// 用户登录还是邮箱登录
function changeEmail() {loginStatus.value = !loginStatus.value;
}
// 登录
const loginForm = reactive({code: "",email: "",password: "",smsCode: "",username: "",uuid: ""
})
const loginRules = reactive({username: [{required: true,message: '用户名为4~16字符之间（中文、字母、数字或下划线）',min: 6, max: 18,trigger: 'blur',},],email: [{ required: true, message: '请填写正确的邮箱格式', trigger: 'blur' },{ min: 6, max: 18, message: '邮箱字符为6~18之间', trigger: 'blur' },],password: [{required: true,message: '密码为6~18位字母、数字和符号',min: 6, max: 18,trigger: 'blur',},// { min: 6, max: 18, message: '密码字符为6~18之间', trigger: 'blur' },],
})
// 注册
const registerForm = reactive({code: "",email: "",password: "",smsCode: "",username: "",uuid: ""
})
const registerRules = reactive({username: [{ required: true, message: '用户名为4~16位之间字符', trigger: 'blur', },{ min: 4, max: 16, message: '4~16位中文、字母、数字或下划线', trigger: 'blur' },],email: [{ required: true, message: '请填写正确的邮箱格式', trigger: 'blur' },{ min: 6, max: 18, message: '邮箱为6~18位之间字符', trigger: 'blur' },],password: [{required: true,message: '密码为6~18位字符，必须包含字母、数字和符号',min: 6, max: 18,trigger: 'blur',},],smsCode: [{required: true,message: '请输入验证码',trigger: 'blur',},],
})
const checked1 = ref(false);//登录协议
const userDeal = ref(false);//提示用户
const registerCks = ref(false);//注册协议
const registerDeal = ref(false);//注册状态
const authInfo = reactive({})//注册uuid
//登录信息
const loginInfo = reactive({})
// const formLoading = ref(false);
//弹框默认
const dialogFormVisible = ref(false);
//tab默认选中
const activeName = ref('login_one')
//注册/登录
const loginOrRetister = ref(true);
//验证码时间
const registerNum = ref(180);
//文字还是验证码
const authCodeNum = ref(true);

3、事件方法

<script setup lang='ts'>// tab切换事件
function handleClick(tab, event) {const iAgree = document.querySelector(".form_footer");if (activeName.value === "register_two") {// 注册loginOrRetister.value = true;iAgree.style.display = "none";} else if (activeName.value === "login_one") {// 登录loginOrRetister.value = false;iAgree.style.display = "block";}
}// 右上角注册/登录状态切换
function choseResgister() {if (loginOrRetister.value === true) {loginOrRetister.value = false;activeName.value = "register_two";} else if (loginOrRetister.value === false) {loginOrRetister.value = true;activeName.value = "login_one";}
}</script>

这里的Element Plus组件使用的全局引入，所以可以直接使用；

样式大家自己写下吧！

然后点击登录、注册时，表单里的输入框验证，也有做，但是有时管用，有时不管用，这里给大家文档地址，自己看吧！
