在 Angular 8 中使用带有枚举的 Formbuilder

问题描述

有没有办法将 Enum 与 Formbuilder 名称联系起来?下面，是一个枚举，并且想要将枚举转换为它的字符串，并与 Formbuilder 一起使用(而不是在 formbuilder 中使用字符串)

Is there a way to tie an Enum to Formbuilder names? Below, is an enum, and want to convert enum to its string, and use with Formbuilder (rather than using strings in formbuilder)

这在 Angular 中可行吗?

Is this possible in Angular?

enum address{   
    city, 
    state, 
    zip
}

this.addressForm = this.formBuilder.group({
  'city': [null, [Validators.required, Validators.maxLength(200)]],
  'state': [null, [Validators.maxLength(200)]],
  'zip':[null,[Validators.maxLength(200)]]
});

推荐答案

是否有使用枚举的特定原因?

Is there a specific reason to use an enum?

我认为界面更符合您的要求:

I think an interface is more what you want:

interface address {
    city: string;
    state: string;
    zip: string;
}

如果你走接口路线，你可以在这里看看我的回答 参考 Angular 8 中强类型列表中的 FormBuilder 成员.它应该适用于您想要完成的工作.

If you go the interface route, you could take a look at my answer over here Refer to FormBuilder Members in a Strongly Typed list in Angular 8. It should apply to what you're trying to accomplish.
