title: Determining If jQuery UI Draggable Is Initialized
body: <p>Is there a way of testing to determine if a <code>jQuery UI draggable</code> class has been initialized?</p>
  
  <p>I have a series of divs with the class "draggable1".</p>
  
  <p>For reasons beyond the scope of this question, I do not want to initialize the class in advance, rather I need to initialize the class the first time one of the divs is selected, which I do in a click event handler. Then, I assume I don't want to keep re-initializing the class every time another div is selected. So, I need to determine if one of the divs has already been clicked and initializing the draggable is not necessary.</p>
  
  <p>Or am I looking at this incorrectly? Should I simply re-initialize the draggable class every time another div is selected?</p>
