NgbTypeahead selectItem get clicked item ngBootstrap angular2

问题

In this answer, it was explained to me to use selectItem to get the select event.

But at this point, the model I bound to the text box is still the original text the user typed, not the select item.

I use

(selectItem)="search(model)"

to get the event, and in TS

search(model) { 
this._service.search(model).subscribe(
  results => this.results = results,
  error => this.errorMessage = <any>error);

}

but as mentioned above, that calls my backend with the user-typed text, not the full text of the selected item of the typeahead.

My backend logs

2017/03/24 20:44:14 /api/typeahead/ok
2017/03/24 20:44:14 /api/search/ok

where the second should be /api/search/$actualSelectedItem.

You should be using $event to get the selected Items as below

<input type="text" class="form-control" (selectItem)="selectedItem($event)" [(ngModel)]="model" [ngbTypeahead]="search" [resultFormatter]="formatter" />
<hr>
<pre>Model: {{ model | json }}</pre>
clicked item {{clickedItem}}

Your method should be as

selectedItem(item){
    this.clickedItem=item.item;
    console.log(item);
  }
