 本文实例讲述了js实现同一页面可多次调用的图片幻灯切换效果。分享给大家供大家参考。具体实现方法如下：

代码如下:

//声明命名空间
var $o = new Object();
//基础方法
$o.base = {
e:function(a,f){
for(var i=0,j=a.length;i }
}
$o. slide = function (id,arg){
var arg = arg||{},
t = document.getElementById(id),
a = t.getElementsByTagName("a"),
lis = [],
cl = arg.color||'#f30',
ctm = arg.time*1000||2000,
w = t.clientWidth,
h = t.clientHeight,
b = [''],
index = 0,
$ = null,
$ = null;
function change(i){
if(!!$){clearTimeout($);}
index = !isNaN(i)?i:index+1;
if(index >= a.length){index = 0;}
$o.base.e(lis,function(k){if(k == index){c(1,this);}else{c(0,this)}});
var to = - index*h;
if(a[0].offsetTop == to){
return;
}else{
if(!!$){clearInterval($);}
$ = setInterval(function(){
var ot = a[0].offsetTop;
v = Math[to if(ot == to){clearInterval($);$=null;st();}
ot += v;
a[0].style.marginTop = ot + "px";
},30)
};
}
function c(b,o){
o.style.backgroundColor = !!b?cl:"#fff";
o.style.color = !!b?"#fff":cl;
}
function st(){
if(!!$)clearTimeout($);
$ = setTimeout(function(){change()},ctm);
}
with(t.style){overflow = 'hidden';position = 'relative';}
$o.base.e(a,function(n){
this.style.display = "block";
with(this.firstChild.style){borderWidth = '0';width = w + 'px';height = h + 'px';}
b.push('

' + (n+1) + '

');
});
b.push('');
t.innerHTML += b.join("");
lis = t.getElementsByTagName("li");
$o.base.e(lis,function(n){
if(n == index){c(1,this)}
this.onmouseover = function(){
if(n!=index)change(n);
}
});
st();
}

new $o.slide("aa");











new $o.slide("bb",{color:'#000',time:0.2});











new $o.slide("cc",{color:'green'});
