我认为这是一个糟糕的解决方案。如果要使用将函数传递给组件@input()，则需要@Output()装饰器。
export class SuggestionMenuComponent {
@Output() onSuggest: EventEmitter<any> = new EventEmitter();
suggestionWasClicked(clickedEntry: SomeModel): void {
this.onSuggest.emit([clickedEntry, this.query]);
}
}
<suggestion-menu (onSuggest)="insertSuggestion($event[0],$event[1])">
</suggestion-menu>
