The useRef is one of the react hooks that tracks the state of DOM elements.
We can also control the state of DOM elements using this hook.
・src/Example.js
import { useRef, useState } from "react";
const Video = () => {
const [playing, setPlaying] = useState();
const videoRef = useRef();
return (
<div>
<video style={{ maxWidth: "100%" }} ref={videoRef}>
<source src="./sample.mp4"></source>
</video>
<button
onClick={() => {
if (playing) {
videoRef.current.pause();
} else {
videoRef.current.play();
}
setPlaying((prev) => !prev);
}}
>
{playing ? "Stop" : "Play"}
</button>
</div>
);
};
const Example = () => {
return (
<>
<Video />
</>
);
};
export default Example;
・We set a value of useRef as videoRef to the video element's ref attribute.
・When we press the button, we can control the video action using videoRef.current.pause() or videoRef.current.play() in the button's onClick function.
・This is a playing action.
・This is a stopping action.
Sorry I can't show the action as video.
