findDOMNode is deprecated and will be removed in the next major release. Instead, add a ref directly to the element you want to reference

`findDOMNode`是React中的一个方法,用于获取一个组件的DOM节点。然而,它已经被弃用了,并且在未来的主要版本中将被移除。相反,React建议直接在你需要引用的元素上添加一个ref属性,然后通过访问`ref.current`属性来访问DOM节点。这样可以避免在不必要的情况下访问和遍历整个组件树来查找DOM节点,从而提高了性能。

findDOMNode is deprecated and will be removed in the next major release.
findDOMNode is a method in React that allows you to get a reference to a DOM node that is rendered by a component. However, it has been deprecated and will be removed in the next major release of React.
This means that you should avoid using findDOMNode in your code and instead use other ways to interact with the DOM, such as refs or the useEffect hook. Using findDOMNode can lead to performance issues and can make your code harder to maintain.
If you need to access a DOM node in a component, you can use the useRef hook to create a reference to the node. For example:
```
import { useRef, useEffect } from 'react';
function MyComponent() {
const myRef = useRef(null);
useEffect(() => {
console.log(myRef.current);
}, []);
return <div ref={myRef}>Hello World!</div>;
}
```
In this example, we create a reference to the div element using the useRef hook and then log it to the console using the useEffect hook.
antdesignpro 引用pro-components报错 findDOMNode is deprecated and will be removed in the next major release.
Ant Design Pro 是一个企业级中后台前端/设计解决方案,它基于 Ant Design 设计体系,而 pro-components 是其中一个组件库。
关于报错 "findDOMNode is deprecated and will be removed in the next major release",这是因为 React 17 版本中将会移除 findDOMNode 方法,官方建议在代码中尽可能避免使用该方法。
如果你在使用 antdesignpro 引用 pro-components 时遇到这个报错,可以尝试更新 antd 和 pro-components 的版本,或者在代码中避免使用 findDOMNode 方法。另外,如果你的项目需要使用 React 17 版本,也需要注意避免使用 findDOMNode 方法。
