React是否会自动修剪已从DOM中删除其挂载点的组件？ [英] Does React automatically prune components which have had their mount points removed from the DOM?

问题描述

例如，如果我使用renderComponent渲染到DOM节点，那么手动删除DOM节点，我只是泄漏了内存吗？是否已将已删除的DOM节点呈现的React组件进行了修剪？

For instance, if I use renderComponent to render to a DOM node, then delete the DOM node manually, did I just leak memory? Is the React component which was rendered to the deleted DOM node pruned?

推荐答案

您可能泄露了内存。使用 React.unmountComponentAtNode（节点）

You probably leaked memory. Use React.unmountComponentAtNode(node)
