在对象映射数组中返回 HTML 标记

Question

I have an array of objects mapping to return as a component but some of the content has an HTML tag. How can I return it rendering the HTML tag inside it?

const listContent = [
  {
    title: 'Sample Title 1',
    content: 'Sample of only text here'
  },
  {
    title: 'Sample Title 2',
    content: 'Sample of only text here with <span>Should render as span</span>'
  },
];


{listItemContent.map(item => (
  <ListItem>
    <h1>{item.title}</h1>
    <p>{item.content}</p>
  </ListItem>
))}

Answer 1

You probably want to use React fragments , like so:

const listContent = [
  {
    title: 'Sample Title 1',
    content: 'Sample of only text here'
  },
  {
    title: 'Sample Title 2',
    content: <>
      Sample of only text here with <span>Should render as span</span>
    </>
  },
];
...
{listItemContent.map(item => (
  <ListItem key={item.key}>
    <h1>{item.title}</h1>
    <p>{item.content}</p>
  </ListItem>
))}

Note that you should ideally also add a key to each React element of an array.

You might want to use react's dangerouslySetInnerHTML

{listItemContent.map(item => (
   <ListItem key={item.key}>
   <h1>{item.title}</h1>
   <p dangerouslySetInnerHTML={{__html: item.content}} />
   </ListItem>
))}
