在StrictMode中，findDOMNode已弃用。向findDOMNode传递了StrictMode内部的DraggableCore的实例

问题描述

可拖动包在严格模式下导致错误：

显然他们从来没有修复过https://github.com/STRML/react-draggable/issues/440，你们有什么好的/优雅的解决方案吗？

推荐答案

根据https://github.com/STRML/react-draggable/blob/v4.4.2/lib/DraggableCore.js#L159-L171上的官方Git存储库

/* If running in React Strict mode, ReactDOM.findDOMNode() is deprecated.
* Unfortunately, in order for <Draggable> to work properly, we need raw access
* to the underlying DOM node. If you want to avoid the warning, pass a `nodeRef`
* as in this example:
*/

function MyComponent() {
    const nodeRef = React.useRef(null);
    return (
        <Draggable nodeRef={nodeRef}>
            <div ref={nodeRef}>Example Target</div>
        </Draggable>
    );
}

/*
* This can be used for arbitrarily nested components, so long as the ref ends up
* pointing to the actual child DOM node and not a custom component.
*/

起作用了！
