AdPlugg API to check if there is ads visible

You can do this using the AdPlugg JavaScript SDK's event system and AdPlugg.on().

Listen for "adplugg:renderStart" events and show your "advertisement" text in the callback function. We don't have much for documentation for the AdPlugg.on() feature yet but you can see an example of how to use it in our AMP implementation (https://github.com/ampproject/amphtml/blob/master/ads/adplugg.js).

Note that for AMP we are doing the following:

• Loading the https://www.adplugg.com/serve/js/ad.js script. This script is slightly different than the one that currently comes down with the AdPlugg Snippet in that it doesn't autorun.
• We then programatically create an AdPlug Ad Tag and insert it in the DOM.
• We then register event listeners on the tag.
• Lastly we call AdPlugg.run (via the lazy loading command queue).

Also note that AdPlugg.on() is based on jQuery's on function, we just added a selector parameter as the first parameter. For this parameter you can pass in a jQuery object, jQuery selector string or a DOMElement.

AdPlugg.on() currently supports the following events:

• adplugg:renderStart
• adplugg:renderEnd
• adplugg:noContentAvailable

Hopefully we'll have more complete documentation for AdPlugg.on() and other advanced features of the AdPlugg JavaScript SDK soon.
