Topic: autocomplete initialize with value
Initialize autocomplete searchText field with some text, for example name of the logged in user
I followed "Remote Data" section of https://mdbootstrap.com/docs/angular/forms/autocomplete/ to setup autocomplete in our sample app. I was wondering if there is a way to initialize searchText with some text
Remote data section of https://mdbootstrap.com/docs/angular/forms/autocomplete/
ngOnInit(): void { this.searchText.next("alis"); }
I did not see value "alis" in the searchText in UI.

I was able to accomplish initialization by changing searchText type from Subject to BehaviorSubject and initializing value in ngOnInit
import { Component, OnInit } from '@angular/core';
import { Observable, BehaviorSubject } from 'rxjs';
import { HttpClient } from '@angular/common/http';
import { map } from 'rxjs/operators';
@Component({
selector: 'remote-auto-completer',
templateUrl: './remote-auto-completer.component.html',
styleUrls: ['./remote-auto-completer.component.scss'],
})
export class RemoteAutoCompleterComponent {
searchText = new BehaviorSubject<string>("");
url = 'https://swapi.co/api/people/?search=';
results: Observable<any>;
data: any = [];
constructor(private httpClient: HttpClient) { }
ngOnInit() {
this.searchText.next("John");
this.httpClient.get(this.url).subscribe((data: any) => {
console.log(data);
this.data = data;
this.results = this.searchText.pipe(
startWith(''),
map((value: string) => this.filter(value))
);
});
}
filter(value: string): string[] | undefined {
const filterValue = value.toLowerCase();
if (this.data && this.data['results']) {
return this.data['results'].filter((item: any) =>
item.name.toLowerCase().includes(filterValue)
);
}
}
}

We will take a closer look at that and update the documentation.
