interface
A lifecycle hook that is called when a directive, pipe, or service is destroyed. Use for any custom cleanup that needs to occur when the instance is destroyed.
interface OnDestroy {
ngOnDestroy(): void
} NgComponentOutlet AsyncPipe HashLocationStrategy PathLocationStrategy AbstractFormGroupDirective NgModel NgModelGroup RadioControlValueAccessor FormControlDirective FormControlName FormGroupDirective FormArrayName FormGroupName NgSelectOption RouterLinkWithHref RouterLinkActive RouterOutlet RouterPreloader UpgradeComponent | ngOnDestroy() |
|---|
| A callback method that performs custom clean-up, invoked immediately before a directive, pipe, or service instance is destroyed. |
|
The following snippet shows how a component can implement this interface to define its own custom clean-up method.
@Component({selector: 'my-cmp', template: `...`})
class MyComponent implements OnDestroy {
ngOnDestroy() {
// ...
}
}
