const onMapClick = (area, index) => {
	const tip = `click map${index + 1}`;
	console.log(tip, area);
	alert(tip);
}

<ImageMap

	onMapClick={onMapClick}
/>

// in hooks
const ImageMapComponent = React.useMemo(() => <ImageMap className="usage-map" src={img} map={mapArea} onMapClick={onMapClick} />, [mapArea, img]);
