access to parent object within each()

access to parent object within each()

OK.  I've created an object with properties and methods.  The object is associated with a form.  The object iterates through the form and finds any inputs that are required.  It then uses each to apply validation to each of the found inputs.  From within each(), I need to access properties and methods of the parent object, but now this refers to the current collection object.  How do I access the containing object?
