示例4: return
return (elementOrNode = null, options = null) => {
// When passed a node, call the hook straight away.
if (!isValidElement(elementOrNode)) {
const node = elementOrNode
hook(node, options)
// return the node so it can be chained (e.g. when within callback refs
// <div ref={node => connectDragSource(connectDropTarget(node))}/>
return node
}
// If passed a ReactElement, clone it and attach this function as a ref.
// This helps us achieve a neat API where user doesn't even know that refs
// are being used under the hood.
const element: ReactElement | null = elementOrNode
throwIfCompositeComponentElement(element as any)
// When no options are passed, use the hook directly
const ref = options ? (node: Element) => hook(node, options) : hook
return cloneWithRef(element, ref)
}
