Question

How to use innerHTML in React? Explain with Example.

Answer 1

The dangerouslySetInnerHTML attribute is React's replacement for using innerHTML in the browser DOM. Just like innerHTML, it is risky to use this attribute considering cross-site scripting (XSS) attacks. You just need to pass a __html object as key and HTML text as value.

In this example MyComponent uses dangerouslySetInnerHTML attribute for setting HTML markup:

function createMarkup() {
  return { __html: "First · Second" };
}

function MyComponent() {
  return <div dangerouslySetInnerHTML={createMarkup()} />;
}
