How to load conditionally templateUrl html file in Angular 5 component

问题

There is one scenario in my project, Consider, I have one testDynamic component

@Component({
    templateUrl: "./test-dynamic.html", // Need to override this file
    styleUrls: ['./test-dynamic.css']
})
export class testDynamic {
    constructor() { }
}

here need to check if an override1.html file is exists in override folder then load this file as templateUrl otherwise load the component default test-dynamic.html. Any idea how to achieve this.?

回答1:

You can't add more than one HTML file.

What you can do is, use *ngIf or *ngSwitchCase to show only parts of the template if that is your intention. Then you have only one template html file.

Then html of your template will be something like this:

<div *ngIf="YOUR_CONDITION">View 01</div>
<div *ngIf="YOUR_CONDITION">View 02</div>
