Hello,
i try to create a data filter and i have to say that i am totally new to
Angular.
So, if a user clicks on a special checkbox the data should be displayed and
the rest should be blacklisted.
At the moment when a checkbox is checked, the whole list is blacklisted.
At this point, i want to filter the gender. If checkbox 1(-> value = m) is
checked, each female(-> f) have to be blacklisted.
*home.component.ts*
const HEROES: Hero[] = [
{ id: 11, name: 'Mr. Nice', gender : 'm' },
{ id: 12, name: 'Narco', gender : 'f' },
{ id: 13, name: 'Bombasto', gender : 'm' },
{ id: 14, name: 'Celeritas', gender : 'f' },
{ id: 15, name: 'Magneta', gender : 'm' },
{ id: 16, name: 'RubberMan', gender : 'm' },
{ id: 17, name: 'Dynama', gender : 'f' },
{ id: 18, name: 'Dr IQ', gender : 'm' },
{ id: 19, name: 'Magma', gender : 'm' },
{ id: 20, name: 'Tornado', gender : 'f' }
];
@Pipe({
name: 'filterPipe'
})
export class FilterPipe implements PipeTransform {
transform(check: any[], checked: any[]): any {
return checked
? check.filter(gender => gender.heroes == checked)
: check;
}
}
*home.component.html*
<div class="row">
<div class="col-xs-12">
<form class="form-inline">
<div class="form-group">
*<input type="checkbox" id="checkbox11" [(ngModel)]="checked"
[ngModelOptions]="{standalone: true}" name="gender" value="m">*
* <label for="checkbox11">1</label>*
</div>
<div class="form-group">
<input type="checkbox" id="checkbox22" checked="checked">
<label for="checkbox22">2</label>
</div>
<div class="form-group">
<input type="checkbox" id="checkbox33" checked="checked">
<label for="checkbox33">3</label>
</div>
</form>
<h1>{{title}}</h1>
<h2>My Heroes</h2>
*<ul class="heroes">*
* <li *ngFor="let hero of (heroes | filterPipe: checked)"*
* [class.selected]="hero === selectedHero"*
* (click)="onSelect(hero)">*
* {{hero.id}} - {{hero.name}} - {{ hero.gender }}*
* </li>*
* </ul>*
<div *ngIf="selectedHero">
<h2>{{selectedHero.name}} details!</h2>
<div><label>id: </label>{{selectedHero.id}}</div>
<div>
<label>name: </label>
<input [(ngModel)]="selectedHero.name" placeholder="name">
</div>
</div>
</div>
</div>
Thx for help
Stefan
