How to check for broken images in React with JavaScript?
To check for broken images in React with JavaScript, we can set the onError of the img element to a error handler function.
For instance, we write:
import React from "react";
export default function App() {
const onError = (e) => {
console.log(e);
};
return (
<>
<img onError={onError} src="abc" alt="abc" />
</>
);
}
to set the onError of the img element to the onError function.
Since the src prop is set to an invalid URL, we see the error object logged in onError.
