nl_tokens: Returns either the offsetHeight or the height of this element based on CSS height adjusted by padding or borders when needed to simulate offsetHeight when offsets aren t available . This may not work on display : none elements if a height has not been set using CSS .
pl_tokens: function ( ) { var me = this , h = Math . max ( me . dom . offsetHeight , me . dom . clientHeight ) ; if ( ! h ) { h = parseFloat ( me . getStyle ( HEIGHT ) ) || 0 ; if ( ! <mask> . isBorderBox ( ) ) { h += me . getFrameWidth ( 'tb' ) ; } } return h ; }
