How to filter content using ngSwitch and taking only first two letters of a string? I have tried to solve it myself some how but I’m doing it wrong way I guess.
<ion-segment scrollable mode="md" [(ngModel)]="filter">
<ion-segment-button mode="md" class="ce-sm-segment" value="all" (click)="showSelectedLetterPopup('all')">
<ion-icon name="medical"></ion-icon>
</ion-segment-button>
<ion-segment-button mode="md" class="ce-sm-segment" value="starred" (click)="showSelectedLetterPopup('☆')">
<ion-icon name="star-outline"></ion-icon>
</ion-segment-button>
<ion-segment-button mode="md" *ngFor="let ltr of twoLettersList" class="ion-text-lowercase" value={{ltr}}
(click)="showSelectedLetterPopup(ltr)">
{{ltr}}
</ion-segment-button>
</ion-segment>
<div [ngSwitch]="filter.substring(0, 2)" *ngFor="let word of (words ? words : [])">
<ion-item *ngSwitchCase="filter" routerLink="/tabs/dictionary/word-detail/{{word.id}}">
<ion-label>
{{word.word_chechen}}
</ion-label>
</ion-item>
</div>
I have following objects in the page component:
twoLetterArray = ['aa', 'ab', 'ac', 'ad', 'ae']
words = ['Aachen', 'Abaco', 'acetone', 'adaptation', 'Aegeus']
