b.giorno... mi ci sto impazzando da stamattina...
ho utilizzato questo script, che utilizza "jquery" integrato in una pagina php per creare lo scrool delle foto che sono posizionate in una data cartella, il tutto l'ho adattato affinchè divenga un modulo per joomla 1.5, che da la possibilità di scegliere la cartella lo sfondo la dimenzione ecc...
funziona ma non è esattamente quello che mi serve, l'effetto proposto è simile ad un semplice "marquee", ossia: se ho 10 immagini, scorrono tutte, poi c'è lo spazio bianco, poi riprendono a scorrere.
sapreste aiutarmi?
mi dovreste consigliare come modificare lo script per ottenere un "effetto rullo" ossia, ce dopo l'ultima immagine riparta la prima, senza pause... è possibile???
ecco lo script:
Codice PHP:
<script type="text/javascript">
$(function() {
//remove js-disabled class
$("#viewer").removeClass("js-disabled");
//create new container for images
$("<div>").attr("id", "container").css({ position:"absolute"}).width($(".wrapper").length * <?php echo $awidi; ?>).height(<?php echo $aheii; ?>).appendTo("div#viewer");
//add images to container
$(".wrapper").each(function() {
$(this).appendTo("div#container");
});
//work out duration of anim based on number of images (1 second for each image)
var duration = $(".wrapper").length * 1000;
//store speed for later (distance / time)
var speed = (parseInt($("div#container").width()) + parseInt($("div#viewer").width())) / duration;
//set direction
var direction = "rtl";
//set initial position and class based on direction
(direction == "rtl") ? $("div#container").css("left", $("div#viewer").width()).addClass("rtl") : $("div#container").css("left", 0 - $("div#container").width()).addClass("ltr") ;
//animator function
var animator = function(el, time, dir) {
//which direction to scroll
if(dir == "rtl") {
//add direction class
el.removeClass("ltr").addClass("rtl");
//animate the el
el.animate({ left:"-" + el.width() + "px" }, time, "linear", function() {
//reset container position
$(this).css({ left:$("div#imageScroller").width(), right:"" });
//restart animation
animator($(this), duration, "rtl");
//hide controls if visible

//work out total travel distance
var totalDistance = parseInt($("div#container").width()) + parseInt($("div#viewer").width());
//work out distance left to travel
