我看到了这个。它在抱怨什么并不神秘:
Warning: validateDOMnesting(...): <div> cannot appear as a descendant of <p>. See ... SomeComponent > p > ... > SomeOtherComponent > ReactTooltip > div.
我是SomeComponent和SomeOtherComponent的作者。但后者使用了外部依赖项(来自react-tooltip的ReactTooltip)。这可能并不一定是一个外部依赖，但它让我尝试在这里讨论它是“一些超出我控制的代码”。
鉴于嵌套组件工作正常(看起来)，我应该对这个警告有多担心呢?无论如何，我该如何改变它(如果我不想重新实现一个外部依赖)?有没有我还不知道的更好的设计?
为了完整起见，下面是SomeOtherComponent的实现。它只是渲染this。props。值，当鼠标悬停时:显示“一些工具提示消息”:
class SomeOtherComponent extends React.Component {
constructor(props) {
super(props)
}
render() {
const {value, ...rest} = this.props;
return <span className="some-other-component">
<a href="#" data-tip="Some tooltip message" {...rest}>{value}</a>
<ReactTooltip />
</span>
}
}
谢谢你！
警告出现只是因为演示代码有:
function TabPanel(props) {
const { children, value, index, ...other } = props;
return (
<div
role="tabpanel"
hidden={value !== index}
id={`simple-tabpanel-${index}`}
aria-labelledby={`simple-tab-${index}`}
{...other}
>
{value === index && (
<Box p={3}> // <==NOTE P TAG HERE
<Typography>{children}</Typography>
</Box>
)}
</div>
);
}
像这样修改它就可以了:
function TabPanel(props) {
const {children, value, index, classes, ...other} = props;
return (
<div
role="tabpanel"
hidden={value !== index}
id={`simple-tabpanel-${index}`}
aria-labelledby={`simple-tab-${index}`}
{...other}
>
{value === index && (
<Container>
<Box> // <== P TAG REMOVED
{children}
</Box>
</Container>
)}
</div>
);
}
