html5可以使用代码实现的简单幻灯片,并且能用鼠标滚轮滚动进行换页。
具体代码如下:
<!doctype html>
<html>
<head>
<title></title>
<style>
#slides{
position:absolute;
left:0px;
top:0px;
height:100%;
width:100%;
overflow:hidden;
}
.slide{
position:absolute;
height:600px;
width:800px;
opacity:0.7;
background-color:rgba(0, 128, 196, 0.5) !important;
background-color:#ccc;
border-radius:10px;
left:50%;
top:50%;
margin-top:-300px;
box-shadow:5px 5px 5px rgba(0, 0, 0, 0.5);
transition:all 0.25s ease-in-out 0s;
}
.current{
opacity:1;
margin-left:-400px;
}
.future{
margin-left:450px;
transform: skew(-3deg) scale(0.8);
-webkit-transform: skew(-3deg) scale(0.8);
}
.post{
margin-left:-1250px;
transform: skew(3deg) scale(0.8);
-webkit-transform: skew(3deg) scale(0.8);
}
.far-future{
margin-left:1200px;
transition:none;
}
</style>
</head>
<body>
<div id="slides">
<div class="slide current">1</div>
<div class="slide future">2</div>
<div class="slide far-future">3</div>
<div class="slide far-future">4</div>
<div class="slide far-future">5</div>
<div class="slide far-future">6</div>
<div class="slide far-future">7</div>
</div>
<script> !function(){ var slides = document.getElementById("slides").childNodes;
var l = slides.length; function fslide(e){ var event = e || window.event;
//console.log(event.wheelDelta +" "+ event.detail); for(var i=0;i<l;i++)
{ if(slides[i].className=="slide current")
{ var current_slide = slides[i]; break;
}
}
//var current_slide = document.getElementsByClassName("current")[0];
// getElementsByClassName只有火狐,谷歌等浏览器的较新版本支持
if
((event.wheelDelta < 0 /*ie,谷歌等浏览器*/ || event.detail > 0 /*firefox*/) && nextel(current_slide)){
if(prevel(current_slide)){ prevel(current_slide).className="slide far-future"; }
current_slide.className="slide post"; nextel(current_slide).className="slide current";
if(nextel(nextel(current_slide)))
{
nextel(nextel(current_slide)).className="slide future"; }
}
else if((event.wheelDelta > 0 || event.detail < 0) && prevel(current_slide)){
if(nextel(current_slide)){ nextel(current_slide).className="slide far-future"; }
current_slide.className="slide future"; prevel(current_slide).className="slide current";
if(prevel(prevel(current_slide))){ prevel(prevel(current_slide)).className="slide post"
}
}
}
document.onmousewheel = fslide;
// ie,谷歌等浏览器 if(document.addEventListener)
{ document.addEventListener("DOMMouseScroll",fslide,false);
// firefox } }(); function prevel(el){ if(el.previousSibling == null)
return null; return el.previousSibling.nodeType == 1 ? el.previousSibling : prevel(el.previousSibling);
}
function nextel(el){ if(el.nextSibling == null)
return null; return el.nextSibling.nodeType == 1 ? el.nextSibling : nextel(el.nextSibling);
} </script>
</body>
