reactjs - 如何将 react 组件作为变量传递给子组件？

Question

当我在一个变量中定义了一个组件，并且我试图将它作为子组件传递给一个组件时，Objects are not valid as a React child显示错误。

这样做的正确方法是什么？

function AnotherComponent(){
  return "Another";
}

function ChildComponent(props) {
  const { children, value, index, ...other } = props;

  console.log(children);
  return (
    <Typography
      component="div"
      role="tabpanel"
      hidden={value !== index}
      id={`full-width-tabpanel-${index}`}
      aria-labelledby={`full-width-tab-${index}`}
      {...other}
    >
      <Box p={3}>{children}</Box>
    </Typography>
  );
}

function MainComponent(){
  const tabItems = [
    { "component": AnotherComponent}
  ];

  const [value, setValue] = React.useState(0);

  return (
    <>
      {tabItems.map((tabItem,index) => (
        <ChildComponent value={value} index={tabItem.index}>
          {tabItem.component}
        </ChildComponent>
      ))}
    </>
  )
}

Answer 1

tabItem.component只是一个对象。这应该工作:

{tabItems.map((tabItem, index) => {
    const TheComponent = tabItem.component;
    return (
      <TabPanel value={value} index={tabItem.index}>
        <TheComponent />
      </TabPanel>
    );
  })}
