[Solved] Display Image alt text using vanilla Javascript


Try the following. Note that it uses es6 functions

const images = Array.from( document.querySelectorAll('img') );

images.forEach(image => {
  let alt = image.getAttribute('alt');
  
  if( alt )
  {
    image.insertAdjacentHTML('afterEnd', `<p class="caption">${alt}</p>`); 
  }
});
<img src="https://placeimg.com/240/280/any" alt="These are planets">
<img src="https://placeimg.com/240/280/any" alt="These are something">
<img src="https://placeimg.com/240/280/any" alt="Something else">
<img src="https://placeimg.com/240/280/any" alt="Something">
