Bind Element To Touch Component

Making element to emit wbTouchscroll, requires creating new instance of class TouchComponent.

foo(emitterService: EmitterService): void
{
    let element: any = document.querySelector('.touch-scroll');
    let component: TouchComponent = new TouchComponent(element, emitterService.createEmitter());
}

In our example we used .touch-scroll selector to select DOM element and then create TouchComponent, that will listen to specific changes on this element. If it finds touch, it will emit touch event.

Listen To Touchscroll Event

Touch event is called wbTouchscroll and the event contains three values horizontal and vertical finger position difference after last touch. touchEvent, which is the original TouchEvent.

foo(emitterService: EmitterService): void
{
    let element: any = document.querySelector('.touch-scroll');
    let component: TouchComponent = new TouchComponent(element, emitterService.createEmitter());

    dragable.getEmitter().on('wbTouchscroll' (data: any) => {
        let verticalMovement: number = data.vertical;
        let horizontalMovement: number = data.horizontal;
        let originalEvent: TouchEvent = data.touchEvent;
    });
}
