QUESTION
Ionic v5 React Ion-Slides: How to make a button to the next slide?
Asked 2021-Mar-21 at 17:37Ionic Slides by default rely on swiping the screen.
I am also hosting my Ionic app as a webapp on my site, so I want to let users press a button to advance to the next slide as well. ("Swiping" with a mouse is not intuitive.)
According to the documentation linked above, there is a slideNext
method, but how do I use this? I can't figure out how to call it in my code.
For example, what can I add to onClick
of IonButton
below? (Code based on the example react conference app)
const Tutorial: React.FC<TutorialProps> = ({ history, setHasSeenTutorial, setMenuEnabled }) => {
const [showSkip, setShowSkip] = useState(true);
const slideRef = useRef<HTMLIonSlidesElement>(null);
const handleSlideChangeStart = () => {
slideRef.current!.isEnd().then(isEnd => setShowSkip(!isEnd));
};
return (
<IonPage id="tutorial-page">
<IonContent fullscreen>
<IonSlides ref={slideRef} onIonSlideWillChange={handleSlideChangeStart} pager={false}>
<IonSlide>
<img src="assets/img/ica-slidebox-img-1.png" alt="" className="slide-image" />
<h2 className="slide-title">
Welcome to <b>ICA</b>
</h2>
<p>
The <b>ionic conference app</b> is a practical preview of the ionic framework in action, and a demonstration of proper code use.
</p>
<IonButton onClick={// What do I put here to go to the next slide?} />
</IonSlide>
<IonSlide>
<img src="assets/img/ica-slidebox-img-4.png" alt="" className="slide-image" />
<h2 className="slide-title">Ready to Play?</h2>
<IonButton fill="clear" onClick={startApp}>
Continue
<IonIcon slot="end" icon={arrowForward} />
</IonButton>
</IonSlide>
</IonSlides>
</IonContent>
</IonPage>
);
};
