javascript - Remove function from a jquery object -

How do I remove a function from a jquery object? For example, I have

  $ ('# element'). Func = function {// function body goes here}   
 and later I  func  to  $ ('# element')  wants to remove I've tried  delete  but this does not work thanks.

  $ ('# element') .fn.func = null;   
 or    $ ('# element'). Prototype.funk = null;   
 or    Delete $ ('# element'). Fn.func;   
 or    Delete $ ('# element'). Prototype.funk;   
 To know what a prototype is, take a look here:
