title: Removing a class from parent element
body: <p>I am trying to figure out how to remove a class from a parent element when the element has begun dragging.</p>
  
  <p>Meaning I have <code>&lt;div&gt;</code> elements in a table cell and I want to remove the class "contains_piece" from the table cell once the <code>&lt;div&gt;</code> has started being dragged.</p>
  
  <p>I'm using jQuery to add the class to the cell that the div has been dropped on but cannot figure out how to work out this problem.</p>
