网页上有许多图片切换的幻灯片效果,它们大多用flash实现,那javascript能不能实现他们呢,当然可以,我自己写了一个,和大家一同分享
sx.activex.imagefade={
init:function(imga,fadeint,fadeoutt){
var ti=new Array();
for(var i=0;i
ti[i]=new Image();
ti[i].src=imga[i]
}
var div=document.createElement("div");
var img=document.createElement("img");
img.src=ti[0].src;
var span=document.createElement("span")
span.style.backgroundColor="yellow";
var a=[];
for(var i=0;ia[i]=document.createElement("a")
a[i].style.backgroundColor="red";
a[i].style.width="10px";
a[i].style.margin="2px";
a[i].href="javascript:void(0)";
a[i].onclick=function(r){
return function(){
var t=100;
var t1=0;
var h=window.setInterval(function(){
if(t>=0){
img.style.filter="alpha(opacity="+t+");";
t=t-2;}
else{
window.clearInterval(h);
img.src=ti[r].src;
var h1=window.setInterval(function(){
if(t1<=100){
img.style.filter="alpha(opacity="+t1+");";
t1=t1+2;}
else{
window.clearInterval(h1);
}
},fadeint);
}
},fadeoutt);
}
}(i);
a[i].innerText=i+1;
span.appendChild(a[i]);
}
div.style.position="absolute";
div.style.height="200px";
div.style.width="200px";
div.appendChild(img);
img.style.height="100%";
img.style.width="100%";
span.style.position="absolute";
span.style.right="10px";
span.style.bottom="10px";
div.appendChild(span);
return div;
}
}
