在模态外部单击时关闭Angular2模态

Question

This is the Sample code to have click outside to disable the selection. In this example I am able to deselect but only after I click on the element to activate the listener. I want to use this example to close the modal on click outside of the modal anytime. Any example would be appreciated.

activeIndex = 0;

subscription: any;
init$: Subject<any> = new Subject();
stop$: Subject<any> = new Subject();

ngOnInit() {
  let click$ = Observable.fromEvent(document, 'click');

const clickOutside$ = this.init$.flatMap(() => {
  return click$.takeUntil(this.stop$);
});

this.subscription = clickOutside$.subscribe(() => {
  this.activeIndex = null;
  console.log(1);
  this.stop$.next();
});
}

onItemClicked(event, index: number) {
event.stopPropagation()
this.activeIndex = index;
this.init$.next()
}

ngOnDestroy() {
if(this.subscription) {
  this.subscription.unsubscribe();
}
}

Answer 1

So I have an example of how I handled closing a custom dropdown that I created but I believe it will work for this as well.

So inside of your component:

openModal() { document.addEventListener('click', this.offClickHandler.bind(this)); }

offClickHandler(event:any) {
    if (!event.target.closest(".select-options") && !event.target.closest(".select-input")) { 
        // do whatever you want here
        // close the modal
        // call document.removeEventListener
    }
}

So that will look for a click outside of button and div, but for you I would just set the .closest() to the modal you want to see closed. Then inside the if statement close your modal.
