element-plus el-form表单验证使用方法以及注意事项

const submitForm = async (formEl: FormInstance | undefined) => {
  if (!formEl) return
  await formEl.validate((valid, fields) => {
    if (valid) {
      console.log('submit!') // 位置1
    } else {
      console.log('error submit!', fields)
    }
  })
  // 位置2
}

//表单验证规则

  phone: [{ type: number, validator: checkPhone, trigger: ['blur', 'change'] }],
  password: [{ validator: checkpassword, trigger: ['blur'] }],
