Weird code in calendar subscription

When viewing events in a subscribed calendar on Apple Calendar, each event has some code in the event notes that looks like this:

/******************************************
					-	PREPARE PLACEHOLDER FOR SLIDER	-
				******************************************/

				var setREVStartSize = function() {
					var	tpopt = new Object();
						tpopt.startwidth = 960;
						tpopt.startheight = 600;
						tpopt.container = jQuery('#rev_slider_2_4');
						tpopt.fullScreen = 'off';
						tpopt.forceFullWidth='off';

					tpopt.container.closest('.rev_slider_wrapper').css({height:tpopt.container.height()});tpopt.width=parseInt(tpopt.container.width(),0);tpopt.height=parseInt(tpopt.container.height(),0);tpopt.bw=tpopt.width/tpopt.startwidth;tpopt.bh=tpopt.height/tpopt.startheight;if(tpopt.bh>tpopt.bw)tpopt.bh=tpopt.bw;if(tpopt.bh1){tpopt.bw=1;tpopt.bh=1}tpopt.height=Math.round(tpopt.startheight*(tpopt.width/tpopt.startwidth));if(tpopt.height>tpopt.startheight&&tpopt.autoHeight!='on')tpopt.height=tpopt.startheight;if(tpopt.fullScreen=='on'){tpopt.height=tpopt.bw*tpopt.startheight;var cow=tpopt.container.parent().width();var coh=jQuery(window).height();if(tpopt.fullScreenOffsetContainer!=undefined){try{var offcontainers=tpopt.fullScreenOffsetContainer.split(',');jQuery.each(offcontainers,function(e,t){coh=coh-jQuery(t).outerHeight(true);if(coh

Is there anything I can do to fix this?
