Errore javascript
Salve a tutti, ho trovato uno script javascript che mi permette di ruotare delle immagini e l'ho incluso nelle mie pagine del sito. Solo che quando apro la pagina lo script viene si eseguito correttamente, ma viene visualizzato a fondo pagina un alert di errore javascript in una detemrinata riga.
Vi posto il codice e la riga incriminatavar fadeimages=new Array() //SET IMAGE PATHS. Extend or contract array as needed fadeimages[0]=["ss/1.png", "", ""] //plain image syntax fadeimages[1]=["ss/2.png", "", ""] //plain image syntax fadeimages[2]=["ss/3.png", "", ""] //plain image syntax fadeimages[3]=["ss/4.png", "", ""] //plain image syntax fadeimages[4]=["ss/5.png", "", ""] //plain image syntax var fadebgcolor="" ////NO need to edit beyond here///////////// var fadearray=new Array() //array to cache fadeshow instances var fadeclear=new Array() //array to cache corresponding clearinterval pointers var dom=(document.getElementById) //modern dom browsers var iebrowser=document.all function fadeshow(theimages, fadewidth, fadeheight, borderwidth, delay, pause, displayorder){ this.pausecheck=pause this.mouseovercheck=0 this.delay=delay this.degree=10 //initial opacity degree (10%) this.curimageindex=0 this.nextimageindex=1 fadearray[fadearray.length]=this this.slideshowid=fadearray.length-1 this.canvasbase="canvas"+this.slideshowid this.curcanvas=this.canvasbase+"_0" if (typeof displayorder!="undefined") theimages.sort(function() {return 0.5 - Math.random();}) //thanks to Mike (aka Mwinter) :) this.theimages=theimages this.imageborder=parseInt(borderwidth) this.postimages=new Array() //preload images for (p=0;p<theimages.length;p++){ this.postimages[p]=new Image() this.postimages[p].src=theimages[p][0] } var fadewidth=fadewidth+this.imageborder*2 var fadeheight=fadeheight+this.imageborder*2 if (iebrowser&&dom||dom) //if IE5+ or modern browsers (ie: Firefox) document.write('<div id="master'+this.slideshowid+'" style="position:relative;width:'+fadewidth+'px;height:'+fadeheight+'px;overflow:hidden;"><div id="'+this.canvasbase+'_0" style="position:absolute;width:'+fadewidth+'px;height:'+fadeheight+'px;top:0;left:0;filter:progid:DXImageTransform.Microsoft.alpha(opacity=10);opacity:0.1;-moz-opacity:0.1;-khtml-opacity:0.1;background-color:'+fadebgcolor+'"></div><div id="'+this.canvasbase+'_1" style="position:absolute;width:'+fadewidth+'px;height:'+fadeheight+'px;top:0;left:0;filter:progid:DXImageTransform.Microsoft.alpha(opacity=10);opacity:0.1;-moz-opacity:0.1;-khtml-opacity:0.1;background-color:'+fadebgcolor+'"></div></div>') else document.write('<div><img name="defaultslide'+this.slideshowid+'" src="'+this.postimages[0].src+'"></div>') if (iebrowser&&dom||dom) //if IE5+ or modern browsers such as Firefox this.startit() else{ this.curimageindex++ setInterval("fadearray["+this.slideshowid+"].rotateimage()", this.delay) } } function fadepic(obj){ if (obj.degree<100){ obj.degree+=10 if (obj.tempobj.filters&&obj.tempobj.filters[0]){ if (typeof obj.tempobj.filters[0].opacity=="number") //if IE6+ obj.tempobj.filters[0].opacity=obj.degree else //else if IE5.5- obj.tempobj.style.filter="alpha(opacity="+obj.degree+")" } else if (obj.tempobj.style.MozOpacity) obj.tempobj.style.MozOpacity=obj.degree/101 else if (obj.tempobj.style.KhtmlOpacity) obj.tempobj.style.KhtmlOpacity=obj.degree/100 else if (obj.tempobj.style.opacity&&!obj.tempobj.filters) obj.tempobj.style.opacity=obj.degree/101 } else{ clearInterval(fadeclear[obj.slideshowid]) obj.nextcanvas=(obj.curcanvas==obj.canvasbase+"_0")?

Qualcuno saprebbe darmi delle indicazioni?

Ciao freebreathe,
quello spazio non dovrebbe esserci, dovrebbe essere cosi:
**var pix=document.getElementById(whichId).getElementsByTagName('img');**
