方法一: 使用用户名和密码进行登录
封装代码:
<template> <el-form ref="ruleFormRef" status-icon :model="ruleForms" :rules="rules" label-width="120px" class="demo-ruleForm" > <el-form-item label="用户名:" prop="username"> <el-input v-model="ruleForms.username" autocomplete="off"> <template #prefix> <el-icon class="el-input__icon"> <user/> </el-icon> </template> </el-input> </el-form-item> <el-form-item label="密码:" prop="password"> <el-input type="password" v-model="ruleForms.password" placeholder="Type something"> <template #prefix> <el-icon class="el-input__icon"> <search/> </el-icon> </template> </el-input> </el-form-item> <el-form-item> <el-button type="primary" @click="handleLogin">Submit</el-button> </el-form-item> </el-form> </template> <script lang="ts" setup> import {User, Search} from '@element-plus/icons-vue' import {defineProps, reactive, ref, defineEmits, onMounted, watch} from 'vue' let ruleForms = reactive({username: '', password: ''}) const ruleFormRef = ref(null) const emits = defineEmits(['onSubmit', 'onError']) const props = defineProps({ ruleForm: { type: Object, required: true }, rules: { type: Object, required: true } }) onMounted(() => { ruleForms = props.ruleForm }) watch( () => props.ruleForm, val => { ruleForms = val }, {immediate: true} ) // 登录功能 const handleLogin = () => { ruleFormRef.value.validate(valid => { if (valid) { emits('onSubmit') } else { emits('onError') } }) } </script> <style scoped> </style>
使用:
<template> <div class="login"> <div class="account-panel"> <account-login :ruleForm="ruleForm" :rules="rules" @onSubmit="onSubmit" @onError="onError" /> </div> </div> </template> <script setup> import {reactive} from 'vue' import {ElMessage} from 'element-plus' const ruleForm = reactive({ username: '', password: '' }) const rules = reactive({ username: [ { required: true, trigger: 'blur', message: '用户名长度在2-6之间' } ], password: [ { required: true, trigger: 'blur', validator: '密码不能为空' } ] }) const onSubmit = () => { alert('发送 http请求:') ElMessage({ type: 'success', message: '保存成功' }) } const onError = () => { ElMessage({ type: 'warning', message: '校验失败' }) } </script> <style scoped lang="scss"> .login { margin-top: 50px; margin-left: 20px; } .account-panel { width: 350px; height: 350px; } </style>
方法二: 使用手机验证码登录
封装代码:
<template> <div> <el-form :model="rulesForm" :rules="rules" ref="rulesRef"> <el-form-item label="手机号:" prop="phone"> <el-input v-model="rulesForm.phone" placeholder="请输入手机号"> </el-input> </el-form-item> <el-form-item label="验证码:" prop="countDown"> <el-row :gutter="24"> <el-col :span="18"> <el-input v-model="rulesForm.countDown" placeholder="验证码"></el-input> </el-col> <el-col :span="6"> <el-button @click="sendCode" :disabled="disabled">{{ btnText }}</el-button> </el-col> </el-row> </el-form-item> <el-form-item> <el-button type="primary" @click="handleLogin">Submit</el-button> </el-form-item> </el-form> </div> </template> <script lang="ts" setup> import {defineProps, ref, reactive, watch, defineEmits} from 'vue' import {ElMessage} from "element-plus"; const checkPhone = (rule, value, callback) => { if (!value) { return callback(new Error('手机号不能为空!')) } else { let reg = /^1[3|4|5|7|8][0-9]\d{8}$/ if (reg.test(value)) { callback() } else { return callback(new Error('请输入正确的手机号!')) } } } const rulesForm = ref({}) const disabled = ref(false) const btnText = ref('发送验证码') const props = defineProps({ ruleForm: { type: Object, required: true }, countDown: { type: Number, required: true } }) const emits = defineEmits(['sendCode']) const rules = reactive({ phone: [{required: true, trigger: 'change', validator: checkPhone,}], countDown: [{required: true, message: '验证码不能为空'}] }) const rulesRef = ref(null) const time = ref(0) // 设置倒计时 // 发送验证码 const sendCode = () => { // 手机号必须输入正确,如果不正确,就提示 rulesRef.value.validateField('phone', errMessage => { if (!errMessage) { ElMessage({ type: 'error', message: '请输入正确的手机号' }) } else { // 1、时间开始倒数 // 2、按钮进入禁用状态 // 3、如果倒计时结束,按钮恢复可用状态,按钮文字变成重新发送 // 4、倒计时的过程中,按钮文字为多少秒后重新发送 time.value = props.countDown let timer = setInterval(() => { time.value-- btnText.value = `${time.value}s后重新发送` disabled.value = true if (time.value === 0) { disabled.value = false btnText.value = '重新发送' time.value = props.countDown clearInterval(timer) } }, 1000) emits('sendCode') } }) } // 登录功能 const handleLogin = () => { rulesRef.value.validate(valid => { if (valid) { emits('onSubmit') } else { emits('onError') } }) } watch( () => props.ruleForm, val => { rulesForm.value = val }, {immediate: true} ) </script> <style scoped> </style>
使用:
<template> <div class="login-panel"> <div class="phone-login"> <phone-login :ruleForm="ruleForm" :countDown="countDown" @sendCode="sendCode" @onSubmit="onSubmit" @onError="onError" > </phone-login> </div> </div> </template> <script setup> import {reactive, ref} from "vue"; import {ElMessage} from "element-plus"; const ruleForm = reactive({ phone: '', countDown: '' }) const countDown = ref(30) const sendCode = () => { // 发送验证码接口 ElMessage({ type: 'success', message: '发送验证码成功' }) } const onSubmit = () => { alert('发送 http请求:') ElMessage({ type: 'success', message: '保存成功' }) } const onError = () => { ElMessage({ type: 'warning', message: '校验失败' }) } </script> <style scoped lang="scss"> .login-panel { margin-left: 20px; margin-top: 20px; } .phone-login { width: 350px; height: 350px; } </style>
