Topic: Simulate autocomplete cancel button
bitjuice pro asked 5 years ago
Hi,
I need to simulate mdb-auto-completer clearBtnClicked behavior on typescript file. In others words I need to reset input field programmatically (and hide 'x' button on it).
How can I do it?
Thanks
Marco

Dear @bitjuice
Could you provide your code? Below is my example, and everything seems to work fine (dropdown closes correctly):
<div class="container">
<div class="row">
<div class="col-md-12">
<div class="md-form">
<input
type="text"
class="completer-input form-control mdb-autocomplete"
[ngModel]="searchText | async"
(ngModelChange)="searchText.next($event)"
[mdbAutoCompleter]="auto"
placeholder="Choose your color"
/>
<mdb-auto-completer #auto="mdbAutoCompleter" textNoResults="I have found no results :(">
<mdb-option *ngFor="let option of results | async" [value]="option">
{{ option }}
</mdb-option>
</mdb-auto-completer>
</div>
</div>
</div>
</div>
<hr />
<button (click)="onClick()" mdbBtn type="button">clear</button>
TS:
@ViewChild(MdbAutoCompleterDirective, { static: true })
mdbAutoCompleter: MdbAutoCompleterDirective;
searchText = new Subject();
results: Observable<string[]>;
data: any = ['red', 'green', 'blue', 'cyan', 'magenta', 'yellow', 'black'];
ngOnInit() {
this.results = this.searchText.pipe(
startWith(''),
map((value: string) => this.filter(value))
);
}
filter(value: string): string[] {
const filterValue = value.toLowerCase();
return this.data.filter((item: string) => item.toLowerCase().includes(filterValue));
}
onClick() {
this.mdbAutoCompleter.clear();
}
Best Regards, Bartosz.

Hi,
I'm using the new method clear() : it delete correctly input content, but I also need the dropdown to be closed.
How can I do it?
Thanks

Unfortunately, currently it's not possible to clear this field programatically. We will add a public method for that.
