关键字“private”是保留的(35:12)。您可能需要适当的加载程序来处理此文件类型

angular5 visual-studio-2017 npm angular

我现在在Angular 5应用程序中遇到了一个奇怪的问题。下面给出了错误堆栈。

未能编译。

./src/app/registration/registration。组成部分ts模块解析失败: 保留关键字“private”(35:12),您可能需要适当的加载程序来处理此文件类型。|};|}|构造函数(私有、, fb,FormBuilder);|{| this.form=fb.group({@ ./src/app/app。单元ts 16:0-78@/src/main。ts@多 Web包开发服务器/客户端? http://0.0.0.0:0 ./src/main。输电系统

这是我的密码。

export class RegistrationComponent implements OnInit {

  form;
  constructor(private fb: FormBuilder) {
    this.form = fb.group({
      firstName: ['', Validators.required],
      lastName: ['', Validators.required],
      email: ['', [Validators.required, isEmailValid('email')]],
      password: ['', Validators.required],
      confirmPassword: ['', Validators.required]
    }, { validator: compareValidator('password', 'confirmPassword') });
  }

  function compareValidator(control1, control2) {
    return form => {
      if (form.controls[control1].value !== form.controls[control2].value) {
        return { compareResult: true };
      }
    }
  }

  function isEmailValid(control) {
    return control => {
      var regex = /^(([^<>()\[\]\\.,;:\s@"]+(\.[^<>()\[\]\\.,;:\s@"]+)*)|(".+"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/
      return regex.test(control.value) ? null : { invalidEmail: true };
    }
  }

  ngOnInit() {
  }

}

谁能帮我找出问题所在?如果您需要查看我的软件包版本,我会附上我的 包裹json 文件

有时候一个小问题会让你抓狂,这就是这样一个问题。我不知道为什么我犯了这么小的错误。只需在类外删除这两个函数就解决了这个问题。只需与其他可能会陷入同样境地的人分享。

export class RegistrationComponent implements OnInit {

  form;
  constructor(private fb: FormBuilder) {
    this.form = fb.group({
      firstName: ['', Validators.required],
      lastName: ['', Validators.required],
      email: ['', [Validators.required, isEmailValid('email')]],
      password: ['', Validators.required],
      confirmPassword: ['', Validators.required]
    }, { validator: compareValidator('password', 'confirmPassword') });
  }

  ngOnInit() {
  }

}

function compareValidator(control1, control2) {
  return form => {
    if (form.controls[control1].value !== form.controls[control2].value) {
      return { compareResult: true };
    }
  }
}

function isEmailValid(control) {
  return control => {
    var regex = /^(([^<>()\[\]\\.,;:\s@"]+(\.[^<>()\[\]\\.,;:\s@"]+)*)|(".+"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/
    return regex.test(control.value) ? null : { invalidEmail: true };
  }
}

如果删除关键字“function”并在类内使用define-your-function,则会出现以下错误: isEmailValid未定义 .
