Question

Looking for a way to get the dimensions (width and height) of an external image.
I have used prop() and attr(), but they don’t return any values. Just an error.

Example:

<a href="pathtotheimage">some link</a>

jQuery

var path = 'https://source.unsplash.com/random/600x300/?montreal';
$("<img/>").attr('src', path).load(function() {
    console.log(this.width, this.height);
 });

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.2.4/jquery.min.js"></script>

Vanilla Javascript

var path = 'https://source.unsplash.com/random/600x300/?montreal';
var img = new Image();
img.src = path;
img.addEventListener('load', function() {
  console.log(this.width, this.height);
});
