Con gli z-index non cambia niente. Non capisco proprio perchè non funziona in modo corretto. Se elimino l'effetto fade, e quindi carico subito la div, funziona ovviamente.
Devo attendere che qualcuno lo testi con Safari.
Oppure non devo intervenrire con lo z-index all'intern del JS che comanda il fade?
codice:
// applica o nasconde l'opacità con link
function opacity(id, opacStart, opacEnd, millisec) {
//speed for each frame
var speed = Math.round(millisec / 100);
var timer = 0;
//determine the direction for the blending, if start and end are the same nothing happens
if(opacStart > opacEnd) {
for(i = opacStart; i >= opacEnd; i--) {
setTimeout("changeOpac(" + i + ",'" + id + "')",(timer * speed));
timer++;
}
} else if(opacStart < opacEnd) {
for(i = opacStart; i <= opacEnd; i++) {
setTimeout("changeOpac(" + i + ",'" + id + "')",(timer * speed));
timer++;
}
}
}
//change the opacity for different browsers
function changeOpac(opacity, id) {
var object = document.getElementById(id).style;
object.opacity = (opacity / 100);
object.MozOpacity = (opacity / 100);
object.KhtmlOpacity = (opacity / 100);
object.filter = "alpha(opacity=" + opacity + ")";
}
function shiftOpacity(id, millisec) {
//if an element is invisible, make it visible, else make it ivisible
if(document.getElementById(id).style.opacity == 0) {
opacity(id, 0, 100, millisec);
} else {
opacity(id, 100, 0, millisec);
}
}
function blendimage(divid, imageid, imagefile, millisec) {
var speed = Math.round(millisec / 100);
var timer = 0;
//set the current image as background
document.getElementById(divid).style.backgroundImage = "url(" + document.getElementById(imageid).src + ")";
//make image transparent
changeOpac(0, imageid);
//make new image
document.getElementById(imageid).src = imagefile;
//fade in image
for(i = 0; i <= 100; i++) {
setTimeout("changeOpac(" + i + ",'" + imageid + "')",(timer * speed));
timer++;
}
}
function currentOpac(id, opacEnd, millisec) {
//standard opacity is 100
var currentOpac = 100;
//if the element has an opacity set, get it
if(document.getElementById(id).style.opacity < 100) {
currentOpac = document.getElementById(id).style.opacity * 100;
}
//call for the function that changes the opacity
opacity(id, currentOpac, opacEnd, millisec)
}
Grazie.
