Can custom types be incorporated into HTML templates in Angular 2?

Let's say we have an enumeration called CustomPages:

export enum CustomPages{
  page1 = 1,
  page2 = 2,
  page3 = 3
}

Now, in our html template, let's try to access this enum.

For instance:

<a class="nav-link" [class.active]="page == CustomPages.page1" href="#">Categories and responses</a>

However, when I try to do this, it results in this error:

Cannot read property 'page1' of undefined

Answer №1

To ensure proper functionality, it is essential to properly define the CustomPages within your component structure.

import {CustomPages} from 'path/to/enum/CustomPages';

@Component({...})
export class YourComponentName {

    CustomPages = CustomPages; // <- make sure to assign the enum to a field of the same name.

    constructor(..){..}

    ...

}
