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

You can use GitHub's own fetch for this:

Frontend: https://github.com/github/fetch
or for Backend, a Node.js version: https://github.com/bitinn/node-fetch

fetch(url)
  .then(function(res) {
    if (res.status == '200') {
      return image;
    } else {
      return placeholder;
    }
  }

Edit: This method is going to replace XHR and supposedly already has been in Chrome. To anyone reading this in the future, you may not need the aforementioned library included.
