[英]Warning: findDOMNode is deprecated in StrictMode. findDOMNode was passed an instance of Transition which is inside StrictMode
[英]findDOMNode is deprecated in StrictMode. findDOMNode was passed an instance of DraggableCore which is inside StrictMode
Draggable 包在严格模式下导致错误:
警告:在 StrictMode 中不推荐使用
findDOMNode
。findDOMNode
传递了一个位于 StrictMode 内的 DraggableCore 实例。 相反,直接向要引用的元素添加 ref。 在此处了解有关安全使用 refs 的更多信息: https : //reactjs.org/docs/strict-mode.html#warning-about-deprecated-finddomnode-usage
显然他们从未修复过https://github.com/STRML/react-draggable/issues/440 ,你有什么好的/优雅的解决方案吗?
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.
*/
有用!
