Javascript scroller not working in firefox
OK I've being struggling today on a page trying to figure out why the scroller is not working in firefox, it works ok in internet explorer, the page has hidden divs that are reveal when a link is click each div has a scroller buttons for the text.
All the scrollers work perfectly in I.E. but doesn't work at all in Fire Fox. Any idea anyone? Here is the javascript from the js file:
// POP UP DIVS CODE //
if(document.getElementById)
document.write('<style type="text/css">.detail {float:left;visibility:hidden;}#numb1 {visibility:visible;}<\/style>');
function reveal(det){
if(!document.getElementById) return;
if (!document.getElementsByClassName){
newContent = document.getElementById(det);
scroller.swapContent(newContent,200, 275);
document.getElementsByClassName = function(cn){
cn = cn.replace(/ +/g, ' ').split(' ');
var ar = [], testname = function(n){
for (var re, i = cn.length - 1; i > -1; --i){
re = new RegExp('(^|\W)' + cn[i] + '(\W|$)');
if(!re.test(n)) return false;
}
return true;
}
for(var d = document.all || document.getElementsByTagName('*'), i = 0; i < d.length; ++i)
if(testname(d[i].className))
ar[ar.length] = d[i];
return ar;
};
document.getElementsByClassName.spoof = true;
}
for (var d = document.getElementsByClassName('detail'), i = d.length - 1; i > -1; --i)
d[i].style.visibility = 'hidden';
document.getElementById(det).style.visibility = 'visible';
if (document.getElementsByClassName.spoof)
document.getElementsByClassName.spoof = document.getElementsByClassName = null;
}
// SCROLL BUTTONS CODE //
function jsScroller (o, w, h) {
var self = this;
var list = o.getElementsByTagName("div");
for (var i = 0; i < list.length; i++) {
if (list[i].className.indexOf("Scroller-Container") > -1) {
o = list[i];
}
}
//Private methods
this._setPos = function (x, y) {
if (x < this.viewableWidth - this.totalWidth)
x = this.viewableWidth - this.totalWidth;
if (x > 0) x = 0;
if (y < this.viewableHeight - this.totalHeight)
y = this.viewableHeight - this.totalHeight;
if (y > 0) y = 0;
this._x = x;
this._y = y;
with (o.style) {
left = this._x +"px";
top = this._y +"px";
}
};
//Public Methods
this.reset = function () {
this.content = o;
this.totalHeight = o.offsetHeight;
this.totalWidth = o.offsetWidth;
this._x = 0;
this._y = 0;
with (o.style) {
left = "0px";
top = "0px";
}
};
this.scrollBy = function (x, y) {
this._setPos(this._x + x, this._y + y);
};
this.scrollTo = function (x, y) {
this._setPos(-x, -y);
};
this.stopScroll = function () {
if (this.scrollTimer) window.clearInterval(this.scrollTimer);
};
this.startScroll = function (x, y) {
this.stopScroll();
this.scrollTimer = window.setInterval(
function(){ self.scrollBy(x, y); }, 40
);
};
this.swapContent = function (c, w, h) {
o = c;
var list = o.getElementsByTagName("div");
for (var i = 0; i < list.length; i++) {
if (list[i].className.indexOf("Scroller-Container") > -1) {
o = list[i];
}
}
if (w) this.viewableWidth = w;
if (h) this.viewableHeight = h;
this.reset();
};
//variables
this.content = o;
this.viewableWidth = w;
this.viewableHeight = h;
this.totalWidth = o.offsetWidth;
this.totalHeight = o.offsetHeight;
this.scrollTimer = null;
this.reset();
};
and this is the piece of js in the html:
var scroller = null;
window.onload = function () {
var el = document.getElementById('basic-yielding');
scroller = new jsScroller(el, 200, 275);
}
Thanks
