jQuery/JavaScript to replace broken images

Question

I have a web page that includes a bunch of images. Sometimes the image isn\'t available, so a broken image is displayed in the client\'s browser.

How do I use jQuery

Answer 1

Sometimes using the error event is not feasible, e.g. because you're trying to do something on a page that’s already loaded, such as when you’re running code via the console, a bookmarklet, or a script loaded asynchronously. In that case, checking that img.naturalWidth and img.naturalHeight are 0 seems to do the trick.

For example, here's a snippet to reload all broken images from the console:

$$("img").forEach(img => {
  if (!img.naturalWidth && !img.naturalHeight) {
    img.src = img.src;
  }
}
