javascript - 如何防止React组件点击事件冒泡到文档？

Question

How to prevent react component click event from bubble up to document ?

我可以确定肯定有什么问题!

所以，也许我应该帮助自己解决这个问题!

我只有一个具有单击事件监听器的框组件，并且该框中有一些受文档单击事件影响的链接组件。如何删除该文档点击事件？

有人可以帮我一个忙吗？

更多详细信息可以在以下链接中找到!

这里是代码链接:https://github.com/ant-design/ant-design/issues/6576

1. 点击没有效果，它应该链接到item3!

删除文档的点击事件

之后就可以了!

这有什么问题吗？

    }
};

App.defaultProps = {
    message: 'Hello!',
    styles: 'App-SideBox-init'
};

App.propTypes = {
    message: PropTypes.string.isRequired,
    styles: PropTypes.string.isRequired,
    width: PropTypes.string
};

export default App;

只需在父组件上创建所有事件处理程序，然后使用props将它们传递给子组件 !
