Noobslide-Skript einfaches alert einfügen funktioniert nicht

[icke]

Ein direkte Anfrage an den Ersteller des Scripts ergab folgenden Lösungsansatz:

	window.addEvent('domready',function(){  
		var sampleObjectItems = []; //NUMBER OF PICTURES IN AN ARRAY  
		  
		//FILL THE ARRAY FOR THE SLIDESHOW  
		for(var i = 1; i < numberOfPictures; i++){  
			sampleObjectItems[i] = "{title: " + i+"}";  
			}  
  
		var info6 = $('picture_box').getNext().set('opacity',0.5);  
		var nS6 = new noobSlide({  
			mode: 'vertical',  
			box: $('picture_box'),  
			items: sampleObjectItems,  
			//HEIGHT FOR THE PICTURES  
			size: 490,  
			addButtons: {  
				previous: $('prev'),  
				play: $('play'),  
				stop: $('stop'),  
				next: $('next')  
			},  
			startItem: -1,  
			button_event: 'click',  
			fxOptions: {  
				duration: 1000,  
				transition: Fx.Transitions.Back.easeOut,  
				wait: false  
			},  
	       onWalk: function(currentItem,currentHandle){  
				alert(this.currentIndex);  
		   }  
		});  
		//walk to next item  
		nS6.next();  
	});

entscheidend ist diese Stelle:

	       onWalk: function(currentItem,currentHandle){  
				alert(this.currentIndex);  
		   }
