ciao a tutti.
Ho questo script per un menu' verticale a comparsa.
Vorrei che una categoria (e relative sottocategorie) siano "aperte" da subito quando la pagina viene caricata ...
Inoltre mi piacerebbe che l'apertura delle sottocategorie sia più lenta e "lineare".
lo script è questo :
function ClickShowHideMenu(id) {
this.box1Hover = true;
this.box2Hover = true;
this.highlightActive = false;
this.init = function() {
if (!document.getElementById(this.id)) {
alert("Element '"+this.id+"' does not exist in this document. ClickShowHideMenu cannot be initialized");
return;
}
this.parse(document.getElementById(this.id).childN odes, this.tree, this.id);
this.load();
if (window.attachEvent) {
window.attachEvent("onunload", function(e) { self.save(); });
} else if (window.addEventListener) {
window.addEventListener("unload", function(e) { self.save(); }, false);
}
}
this.parse = function(nodes, tree, id) {
for (var i = 0; i < nodes.length; i++) {
if (nodes[i].nodeType != 1) {
continue;
}
if (nodes[i].className) {
if ("box1" == nodes[i].className.substr(0, 4)) {
nodes[i].id = id + "-" + tree.length;
tree[tree.length] = new Array();
eval('nodes[i].onmouseover = function() { self.box1over("'+nodes[i].id+'"); }');
eval('nodes[i].onmouseout = function() { self.box1out("'+nodes[i].id+'"); }');
eval('nodes[i].onclick = function() { self.box1click("'+nodes[i].id+'"); }');
}
if ("section" == nodes[i].className) {
id = id + "-" + (tree.length - 1);
nodes[i].id = id + "-section";
tree = tree[tree.length - 1];
}
if ("box2" == nodes[i].className.substr(0, 4)) {
nodes[i].id = id + "-" + tree.length;
tree[tree.length] = new Array();
eval('nodes[i].onmouseover = function() { self.box2over("'+nodes[i].id+'", "'+nodes[i].className+'"); }');
eval('nodes[i].onmouseout = function() { self.box2out("'+nodes[i].id+'", "'+nodes[i].className+'"); }');
}
}
if (this.highlightActive && nodes[i].tagName && nodes[i].tagName == "A") {
if (document.location.href == nodes[i].href) {
nodes[i].className = (nodes[i].className ? ' active' : 'active')
}
}
if (nodes[i].childNodes) {
this.parse(nodes[i].childNodes, tree, id);
}
}
}
this.box1over = function(id) {

document.getElementById(id).className = (this.id_openbox == id ? "box1-open-hover" : "box1-hover");

if (!document.getElementById(id)) return;
document.getElementById(id).className = (this.id_openbox == id ? "box1-open" : "box1");
}
this.box1click = function(id) {
if (!document.getElementById(id)) {
return;
}
var id_openbox = this.id_openbox;
if (this.id_openbox) {
if (!document.getElementById(id + "-section")) {

}
}
grazie a tutti.
