directive
Instantiates a single Component type and inserts its Host View into current View. NgComponentOutlet provides a declarative approach for dynamic component creation.
| Property | Description |
|---|---|
@Input()ngComponentOutlet: Type<any> | |
@Input()ngComponentOutletInjector: Injector | |
@Input()ngComponentOutletContent: any[][] | |
@Input()ngComponentOutletNgModuleFactory: NgModuleFactory<any> |
NgComponentOutlet requires a component type, if a falsy value is set the view will clear and any existing component will get destroyed.
You can control the component creation process by using the following optional attributes:
ngComponentOutletInjector: Optional custom Injector that will be used as parent for the Component. Defaults to the injector of the current view container.
ngComponentOutletContent: Optional list of projectable nodes to insert into the content section of the component, if exists.
ngComponentOutletNgModuleFactory: Optional module factory to allow dynamically loading other module, then load a component from that module.
Simple
<ng-container *ngComponentOutlet="componentTypeExpression"></ng-container>
Customized injector/content
<ng-container *ngComponentOutlet="componentTypeExpression;
injector: injectorExpression;
content: contentNodesExpression;">
</ng-container> Customized ngModuleFactory
<ng-container *ngComponentOutlet="componentTypeExpression;
ngModuleFactory: moduleFactory;">
</ng-container> @Component({selector: 'hello-world', template: 'Hello World!'})
export class HelloWorld {
}
@Component({
selector: 'ng-component-outlet-simple-example',
template: `<ng-container *ngComponentOutlet="HelloWorld"></ng-container>`
})
export class NgComponentOutletSimpleExample {
// This field is necessary to expose HelloWorld to the template.
HelloWorld = HelloWorld;
} A more complete example with additional options:
@Injectable()
export class Greeter {
suffix = '!';
}
@Component({
selector: 'complete-component',
template: `Complete: <ng-content></ng-content> <ng-content></ng-content>{{ greeter.suffix }}`
})
export class CompleteComponent {
constructor(public greeter: Greeter) {}
}
@Component({
selector: 'ng-component-outlet-complete-example',
template: `
<ng-container *ngComponentOutlet="CompleteComponent;
injector: myInjector;
content: myContent"></ng-container>`
})
export class NgComponentOutletCompleteExample {
// This field is necessary to expose CompleteComponent to the template.
CompleteComponent = CompleteComponent;
myInjector: Injector;
myContent = [[document.createTextNode('Ahoj')], [document.createTextNode('Svet')]];
constructor(injector: Injector) {
this.myInjector =
Injector.create({providers: [{provide: Greeter, deps: []}], parent: injector});
}
