Here's my improvement: added parseInt. for some weird reason it didn't work without it.

// usage: jQuery('#my_div1').hasVerticalScrollBar();

(function($) {
    $.fn.hasVerticalScrollBar = function() {
        return this.get(0) ? parseInt( this.get(0).scrollHeight ) > parseInt( this.innerHeight() ) : false;
    };
})(jQuery);
