// 表单校验（账号名+密码）

import { ref } from 'vue'

import { ElMessage } from 'element-plus'
import 'element-plus/theme-chalk/el-message.css'
import { useRouter } from 'vue-router'

import { useUserStore } from '@/stores/userStore'

const userStore = useUserStore()

// 1. 准备表单对象
const form = ref({
  account: '18610848230',
  password: '123456',
})

// 2. 准备规则对象
const rules = {
  account: [
    { required: true, message: '用户名不能为空', trigger: 'blur' }
  ],
  password: [
    { required: true, message: '密码不能为空', trigger: 'blur' },
    { min: 6, max: 14, message: '密码长度为6-14个字符', trigger: 'blur' },
  ]
}

// 3. 获取form实例做统一校验
const formRef = ref(null)
const router = useRouter()
const doLogin = () => {
  const { account, password } = form.value
  // 调用实例方法
  formRef.value.validate(async (valid) => {
    // valid: 所有表单都通过校验  才为true
    console.log(valid)
    // 以valid做为判断条件 如果通过校验才执行登录逻辑
    if (valid) {
      // TODO LOGIN
      await userStore.getUserInfo({ account, password })
      // 1. 提示用户
      ElMessage({ type: 'success', message: '登录成功' })
      // 2. 跳转首页
      router.replace({ path: '/' })
    }
  })
}

// 1. 用户名和密码 只需要通过简单的配置（看文档的方式 - 复杂功能通过多个不同组件拆解）
// 2. 同意协议  自定义规则  validator:(rule,value,callback)=>{}
// 3. 统一校验  通过调用form实例的方法 validate -> true
