title: Jcrop check API presence
body: <p>I am having problems with Jcrop API. I don't think I need to go into detail as why I need this check, but I need to check if the Jcrop API is present so I can destroy it or not create another one if it is already created. Is there a way to check if api is present? Maybe this is Jquery or javascript check, I am quite a beginner. In the Jcrop documentation I found out only how to crate api and destroy it, not how to check if it exists.</p>
  
  <p>Is there any way?</p>
  
  <p>Thank you</p>
