设置多个验证器 - Angular Reactive Form

Question

我试图在控件初始化后设置多个验证器，但它似乎没有添加验证器。

代码：

 this.infoForm.controls['email'].setValidators(this.DynamicValidation(validations));

 DynamicValidation(list: Array<string>): Array<ValidatorFn> {
  const validators: Array<ValidatorFn> = [];
  list.forEach((validator: string) => {
      if (validator === 'required') {
          validators.push(Validators.required);
          return;
        }
         // other validators implementation
    }
 }

另外，有没有办法用像这样的标志设置自定义验证器名称“validators.push({ isMatching:false }”。？

试试这个：

 this.infoForm.controls['email'].setValidators(this.DynamicValidation(validations));

 DynamicValidation(list: Array<string>): Array<ValidatorFn> {
  const validators: Array<ValidatorFn> = [];
  list.forEach((validator: string) => {
      if (validator === 'required') {
          validators.push(Validators.required);
          return validators;
        }
         // other validators implementation
    }
 }
