Hello, my name is Jan Jarfalk and I'm an interaction designer and interface developer. This, my lab, is where I learn and evolve.

Lazy

This Jquery plugin is an on-demand Jquery plugin loader, also known as a lazy loader. Instead of downloading all Jquery-plugins, you might or might not need, when the page loads. Lazy downloads the plugins when you actually use them.

Lazy is very lightweight, super fast, and smart. Lazy will keep track of all your plugins and dependencies and make sure that they are only downloaded once.

How to use Lazy

  1. $.lazy([{
  2.  src: 'jquery.elastic.js',
  3.  name: 'elastic'
  4. }]);
  5.  
  6. // And then you use you plugins as you always do
  7. $('textarea').elastic();

How to work with dependencies

  1. $.lazy([{
  2.  src: 'ui.draggable.js',
  3.  name: 'draggable',
  4.  dependencies: {
  5.   js: ['ui.core.js'],
  6.   css: ['ui.draggable.css']
  7.  }
  8. }]);
  9.  
  10. // And then you use you plugins as you always do
  11. $("#draggable").draggable();

This will load ui.draggable.css and ui.core.js before it loads ui.draggable.js and applies it on the element draggable.

Enable or disable caching

  1. $.lazy([{
  2.  src: 'ui.draggable.js',
  3.  name: 'draggable',
  4.  dependencies: {
  5.   js: ['ui.core.js'],
  6.   css: ['ui.draggable.css']
  7.  },
  8.  cache: true
  9. }]);

Caching is disabled by default, but you can enable it by setting the variable cache to true.
