Salve il mio è un problema che a molti potrà sembrare una banalità..ho creato una galleria immagini con scroll orizzontale e cercavo uno script java che mi aprisse la foto in grande..ho trovato questo script che mi apre la foto sempre nello stesso punto e cioè all'inizio della pagina...cioè scrollando in orizzontale arrivo alla foto 7-8-9- ecc ecc clicco ma mi si apre in un punto dove non la visualizzo..se invece provo lo script su una galleria con scroll verticale mi apre la foto in modo corretto..
Come posso modificare questo codice in modo da far apparire la foto sempre anche scrollando orizzontalmente?
grazie a chiunque presterà attenzione al problemacodice:var thumbnailviewer={ enableTitle: true, //Should "title" attribute of link be used as description? enableAnimation: true, //Enable fading animation? definefooter: '<div class="footerbar">CLOSE X</div>', //Define HTML for footer interface defineLoading: '[img]../funzioni/loading.gif[/img] Loading Image...', //Define HTML for "loading" div /////////////No need to edit beyond here///////////////////////// scrollbarwidth: 16, opacitystring: 'filter:progid:DXImageTransform.Microsoft.alpha(opacity=10); -moz-opacity: 0.1; opacity: 0.1', targetlinks:[], //Array to hold links with rel="thumbnail" createthumbBox:function(){ //write out HTML for Image Thumbnail Viewer plus loading div document.write('<div id="thumbBox" onClick="thumbnailviewer.closeit()"><div id="thumbImage"></div>'+this.definefooter+'</div>') document.write('<div id="thumbLoading">'+this.defineLoading+'</div>') this.thumbBox=document.getElementById("thumbBox") this.thumbImage=document.getElementById("thumbImage") //Reference div that holds the shown image this.thumbLoading=document.getElementById("thumbLoading") //Reference "loading" div that will be shown while image is fetched this.standardbody=(document.compatMode=="CSS1Compat")? document.documentElement : document.body //create reference to common "body" across doctypes }, centerDiv:function(divobj){ //Centers a div element on the page var ie=document.all && !window.opera var dom=document.getElementById var scroll_top=(ie)? this.standardbody.scrollTop : window.pageYOffset var scroll_left=(ie)? this.standardbody.scrollLeft : window.pageXOffset var docwidth=(ie)? this.standardbody.clientWidth : window.innerWidth-this.scrollbarwidth var docheight=(ie)? this.standardbody.clientHeight: window.innerHeight var docheightcomplete=(this.standardbody.offsetHeight>this.standardbody.scrollHeight)? this.standardbody.offsetHeight : this.standardbody.scrollHeight //Full scroll height of document var objwidth=divobj.offsetWidth //width of div element var objheight=divobj.offsetHeight //height of div element var topposition=(docheight>objheight)? scroll_top+docheight/2-objheight/2+"px" : scroll_top+10+"px" //Vertical position of div element: Either centered, or if element height larger than viewpoint height, 10px from top of viewpoint divobj.style.left=docwidth/2-objwidth/2+"px" //Center div element horizontally divobj.style.top=Math.floor(parseInt(topposition))+"px" divobj.style.visibility="visible" }, showthumbBox:function(){ //Show ThumbBox div this.centerDiv(this.thumbBox) if (this.enableAnimation){ //If fading animation enabled this.currentopacity=0.1 //Starting opacity value this.opacitytimer=setInterval("thumbnailviewer.opacityanimation()", 20) } }, loadimage:function(link){ //Load image function that gets attached to each link on the page with rel="thumbnail" if (this.thumbBox.style.visibility=="visible") //if thumbox is visible on the page already this.closeit() //Hide it first (not doing so causes triggers some positioning bug in Firefox var imageHTML='[img]'+link.getAttribute([/img]' //Construct HTML for shown image if (this.enableTitle && link.getAttribute("title")) //Use title attr of the link as description? imageHTML+=' '+link.getAttribute("title") this.centerDiv(this.thumbLoading) //Center and display "loading" div while we set up the image to be shown this.thumbImage.innerHTML=imageHTML //Populate thumbImage div with shown image's HTML (while still hidden) this.featureImage=this.thumbImage.getElementsByTagName("img")[0] //Reference shown image itself this.featureImage.onload=function(){ //When target image has completely loaded thumbnailviewer.thumbLoading.style.visibility="hidden" //Hide "loading" div thumbnailviewer.showthumbBox() //Display "thumbbox" div to the world! } if (document.all && !window.createPopup) //Target IE5.0 browsers only.
