angular2-单击后清除输入字段值

Question

I have problem with reseting my input values. I have search bar with filter functions. When i write some value it shows me list under it and i want to add function to this anchors, when i click some of them it routes me to another component and i want to clear the input value.

My code:

<div class="form">
            <input #query (keyup)="filter(query.value)" type="text" class="form-control" placeholder="Search...">
            <ng-container *ngIf="query.value">
              <div *ngFor="let f of filteredProducts">
                <a (click)="!query.value" [routerLink]="['/product-details/', f.category , f.$key]">{{ f.name }}</a>
              </div>
            </ng-container>
          </div>

i've tried to set this value to null or '' like:

(click)="query.value = ''"

     export class App {

Html

<div class="form">
        <input #query (keyup)="filter(query.value)" type="text" class="form-control" placeholder="Search...">
        <ng-container *ngIf="query.value">
          <div *ngFor="let f of filteredProducts">
            <a href="javascript:void(0)" (click)='myfun(f)'>{{ f.name }}</a>
          </div>
        </ng-container>
      </div>

In class add

@ViewChild("query") input: ElementRef;

myfun(f) {

this.input.nativeElement.value = "";
this.router.navigate(['/product-details/', f.category , f.$key]");
}
