ng.getOwningComponent<T>(elementOrDir: {} | Element): T | null
参数
elementOrDir | {} | Element | DOM element, component or directive instance for which to retrieve the root components. |
返回值
T | null: Component instance whose view owns the DOM element or null if the element is not part of a component view.

For example, if <child-comp> is used in the template of <app-comp> (i.e. a ViewChild of <app-comp>), calling getOwningComponent on <child-comp> would return <app-comp>.
