    $.fn.detectFont = function() {

        var fonts = fontfamily.split(',');

            var dummy = $('<span>wwwwwwwwwwwwwwwlllllllliiiiii</span>').css({'font-family': font, 'font-size':'70px', 'display':'inline', 'visibility':'hidden'}).appendTo('body');
            //console.log(clone, dummy, fonts, font, clone.width(), dummy.width());
            if ( clone.width() == dummy.width() )
                detectedFont = font;
            clone.remove();
            dummy.remove();
        });

       return detectedFont;
    }
})(jQuery);

Need to create two inline elements. One with the font family of the tested element, and one with font family of each individual font and test widths.
