react.js Replace img src onerror

Question

I have a react component that is the detail view from a list.

I am trying to replace the image with a default image if the image does not exist and there is a 404 er

Answer 1

For those like me who also wanted to change the styles of the element and/or change the img source, just do something like this:

<img
  src={'original src url goes here'}
  alt="example"
  onError={(e) => {
     e.target.src = '/example/noimage.png' // some replacement image
     e.target.style = 'padding: 8px; margin: 16px' // inline styles in html format
  }}
/>

Hope it helps!

I used the above method of Arthurs making e.target.onerror = null to stop the infinite loop , but still the infinite loop happened. So , to stop the infinite loop I had to use the below method.I had to find the actual property onError and make it null.

<img src={imageSource}
     onError={(e) => { 
              e.target[Object.keys(e.target).filter(prop=>prop.includes('EventHandler'))[0]].onError = null;
              e.target.src = 'images/avatar.png'; }}
 />

event.target properties

I wrote like this.

import React, { useState } from 'react';
import NoImageSVG from './noImage.svg';

const ImgWithFallback: React.FunctionComponent<{ src: string; alt: string; className: string }> = ({
  src,
  alt,
  className,
}) => {
  const [isUndefined, updateIsUndefined] = useState(false);

  const onError = () => {
    updateIsUndefined(true);
  };

  if (isUndefined) {
    return (
      <div className={className}>
        <NoImageSVG width='5rem' height='5rem' />
      </div>
    );
  }

  return <img src={src} alt={alt} className={className} onError={onError} />;
};

export default React.memo(ImgWithFallback, () => true);

I took @Skay's answer and created a reusable Image component. Posting in case it helps anyone:

import React, { PropTypes } from 'react';

const Image = ({src, fallbackSrc, ...other}) => {
    let element;
    const changeSrc = newSrc => {
        element.src = newSrc;
    };
    return (
        <img src={src} 
             onError={() => changeSrc(fallbackSrc)} 
             ref={el => element=el} 
             {...other} />
    );
};

Image.propTypes = {
    src: PropTypes.string,
    fallbackSrc: PropTypes.string
};
export default Image;
