onload

Onload transitions

onload

Add onload transitions to DOM elements that emit "load" events such as images by adding ".preload" and ".onload" classnames accordingly.

$ component install component/onload

Example js:

var onload = require('onload');
var img = document.querySelector('img');
onload(img);

Example css:

img {
  opacity: 1;
  -webkit-transition: opacity 300ms;
  -moz-transition: opacity 300ms;
  transition: opacity 300ms;
}
 
img.preload {
  opacity: 0;
}
  • onload(el)

Images which are .complete are immediately assigned ".onload" so that effects can be applied to non-cached images only.
