AZ SlideIn has some CSS that you can find here:
slidein.css
A CSS class is added to
AZSlideIn when the
AZSlideIn is active.
<div class="az-slidein az-slidein-active"></div>
This allows you to check if an
AZSlideIn is active or deactivated, (open/closed).
1. new AZSlideIn();
$.subscribeonce("functionlib/azSlideInReady", function (e, data)
{
data.$SlideIn.hasClass("az-slidein-active")
});
2. var AZSlideIn = new AZSlideIn();
AZSlideIn.$SlideIn.hasClass("az-slidein-active")
