用法

import {RcPopper, IArrowInfo} from '@rc-hooks/popper';
import './demo.less';
export default (props: {}) => {
const [showls, setShowLS] = useState(false);

const {arrowDirection} = arrowInfo;
const arrowStyle: CSSProperties = {
borderWidth: '5px',
width: 0,
height: 0,
fontSize: 0,
lineHeight: 0,
borderStyle: 'solid',
display: 'block'
};
switch (arrowDirection) {
case 'top':
Object.assign(arrowStyle, {
borderColor: 'transparent transparent #ccc transparent'
});
break;
case 'bottom':
Object.assign(arrowStyle, {
borderColor: '#ccc transparent transparent transparent'
});
break;
case 'left':
Object.assign(arrowStyle, {

});
break;
case 'right':
Object.assign(arrowStyle, {
borderColor: 'transparent transparent transparent #ccc'
});
break;
}
return (
<span style={arrowStyle} />
);
}, []);
return (

<div style={{marginBottom: '50px'}}>以下popper都是lazyInit的, hover会在隐藏时销毁,click的不会销毁</div>
<div className="part">
