After quite a while without updates, I’ve finally released version 2.0.0 of LazyLoad.
In addition to CSS support, this version of LazyLoad also adds support for parallel loading of multiple resources in browsers that support it. To load multiple resources in parallel, simply pass an array of URLs in a single LazyLoad call.
Using LazyLoad is simple. Just call the appropriate method —
css() to load CSS,
- Firefox 2+
- Google Chrome (all versions)
- Internet Explorer 6+
- Opera 9+
- Safari 3+
- Mobile Safari (all versions)
Other browsers may work, but haven’t been tested. It’s a safe bet that anything based on a recent version of Gecko or WebKit will probably work.
All browsers support parallel loading of CSS. However, only Firefox and Opera currently support parallel script loading while preserving execution order. To ensure that scripts are always executed in the correct order, LazyLoad will load all scripts sequentially in browsers other than Firefox and Opera. Hopefully other browsers will improve their parallel script loading behavior soon.
Sadly, Firefox, Safari, and Google Chrome don’t provide any indication when a CSS file has finished loading. In these browsers, CSS load callbacks will execute after a short delay, but there’s no way to automatically guarantee that the CSS has finished loading before the callback is executed. Luckily, there’s a fairly painless manual workaround that you can use to detect when CSS has finished loading, but it’s not possible for LazyLoad to do it for you.
