一、开发步骤
二、效果图
三、搭建页面
创建views/Login.vue
完整内容在后面
在App.vue中导入Login.vue
csharp
<script setup>
import LoginVue from '@/views/Login.vue'
</script>
<template>
<LoginVue/>
</template>
<style scoped>
</style>四、数据绑定
五、表单校验
vue使用rules实现表单校验------校验用户名和密码
六、访问后端 API 接口，完成注册
七、完整的Login.vue代码
csharp
<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)
//定义数据模型
const registerData = ref({
username: '',
password: '',
confirmPassword: ''
})
//校验密码的函数
const validateConfirmPassword = (rule, value, callback) => {
if (value === '') {
callback(new Error('请再次输入密码'))
} else if (value !== registerData.value.password) {
callback(new Error('两次密码不一致'))
} else {
callback()
}
}
//定义表单校验规则
const rules = {
username: [
{ required: true, message: '请输入用户名', trigger: 'blur' },
{ min: 5, max: 16, message: '长度在 5 到 16 个字符', trigger: 'blur' }
],
password: [
{ required: true, message: '请输入密码', trigger: 'blur' },
{ min: 5, max: 16, message: '长度在 5 到 16 个字符', trigger: 'blur'}
],
confirmPassword: [
{validator: validateConfirmPassword, trigger: 'blur'}
]
}
//调用后台接口完成注册
import { userRegisterService } from '@/api/user.js'
const register = async () => {
let result = await userRegisterService(registerData.value)
if (result.code === 0) {
//注册成功
alert(result.msg ? result.msg : '注册成功')
} else {
//注册失败
alert('注册失败')
}
alert(result.msg ? result.msg : '注册成功')
}
</script>
