I am using the xml photogallery and i would like the next and prev button to actually dissapear and disable when 1st pics is up(for the prev) and the last pic is up and to show up in at the same time when needed.
How do i change the function in the AS?
Thanks a lot
Massimo
this is the code i am using:
var tcount =0
function loadXML(loaded) {
if (loaded) {
xmlNode = this.firstChild;
image = [];
description = [];
thumbnails = [];
total = xmlNode.childNodes.length;
for (i=0; i<total; i++) {
image* = xmlNode.childNodes*.childNodes[0].firstChild.nodeValue;
description* = xmlNode.childNodes*.childNodes[1].firstChild.nodeValue;
thumbnails* = xmlNode.childNodes*.childNodes[2].firstChild.nodeValue;
}
firstImage();
thumbnails_fn(tcount);
} else {
content = "file not loaded!";
}
}
preloader.preload_bar._xscale=0
xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
xmlData.load(“logo.xml”);
