Guide to implementing the collapsible start and stop button feature in Angular

Having an issue in my Angular application with the dashboard page. I've created a button for start or stop (toggle functionality) but it's not working as expected.

.component.ts

toggleCollapse(jammer) {
    this.jammer.isCollapsed ? 'START' : 'STOP'
    this.jammer.isCollapsed ? 'START' : 'STOP'
}

.component.html

<button
    type="button"
    class="btn btn-warning"
    (click)="toggleCollapse()">START</button>

Struggling to get this toggle function to work correctly. Any assistance would be greatly appreciated!

Answer №1

Do you prefer the button label to display either START or STOP?

isCollapsed: boolean = true;

toggleCollapse() {
    this.isCollapsed = !this.isCollapsed;
}

<button
    type="button"
    class="btn btn-warning"
    (click)="toggleCollapse()">{{isCollapsed? 'START' : 'STOP'}}</button>

Answer №2

.component.ts

public isExpanded = true;

toggleExpand() {
    this.isExpanded = !this.isExpanded;
}

.component.html

     <button
        type="button"
        [ngClass]="isExpanded ? 'btn btn-warning' : 'btn btn-success'"
        (click)="toggleExpand()">
        <span *ngIf="isExpanded"> Stop <span>
        <span *ngIf="!isExpanded"> Start <span>
    </button>

Note : Feel free to change the boolean value if needed
