unslider.js——jquery轮播图插件

unslider.js是一款优秀的jquery轮播图插件，大小还不到3k。

压缩后代码：

(function(e,t){if(!e)return t;var n=function(){this.el=t;this.items=t;this.sizes=[];this.max=[0,0];this.current=0;this.interval=t;this.opts={speed:500,delay:3e3,complete:t,keys:!t,dots:t,fluid:t};var n=this;this.init=function(t,n){this.el=t;this.ul=t.children("ul");this.max=[t.outerWidth(),t.outerHeight()];this.items=this.ul.children("li").each(this.calculate);this.opts=e.extend(this.opts,n);this.setup();return this};this.calculate=function(t){var r=e(this),i=r.outerWidth(),s=r.outerHeight();n.sizes[t]=[i,s];if(i>n.max[0])n.max[0]=i;if(s>n.max[1])n.max[1]=s};this.setup=function(){this.el.css({overflow:"hidden",width:n.max[0],height:this.items.first().outerHeight()});this.ul.css({width:this.items.length*100+"%",position:"relative"});this.items.css("width",100/this.items.length+"%");if(this.opts.delay!==t){this.start();this.el.hover(this.stop,this.start)}this.opts.keys&&e(document).keydown(this.keys);this.opts.dots&&this.dots();if(this.opts.fluid){var r=function(){n.el.css("width",Math.min(Math.round(n.el.outerWidth()/n.el.parent().outerWidth()*100),100)+"%")};r();e(window).resize(r)}if(this.opts.arrows){this.el.parent().append('<p class="arrows"><span class="prev">←</span><span class="next">→</span></p>').find(".arrows span").click(function(){e.isFunction(n[this.className])&&n[this.className]()})}if(e.event.swipe){this.el.on("swipeleft",n.prev).on("swiperight",n.next)}};this.move=function(t,r){if(!this.items.eq(t).length)t=0;if(t<0)t=this.items.length-1;var i=this.items.eq(t);var s={height:i.outerHeight()};var o=r?5:this.opts.speed;if(!this.ul.is(":animated")){n.el.find(".dot:eq("+t+")").addClass("active").siblings().removeClass("active");this.el.animate(s,o)&&this.ul.animate(e.extend({left:"-"+t+"00%"},s),o,function(i){n.current=t;e.isFunction(n.opts.complete)&&!r&&n.opts.complete(n.el)})}};this.start=function(){n.interval=setInterval(function(){n.move(n.current+1)},n.opts.delay)};this.stop=function(){n.interval=clearInterval(n.interval);return n};this.keys=function(t){var r=t.which;var i={37:n.prev,39:n.next,27:n.stop};if(e.isFunction(i[r])){i[r]()}};this.next=function(){return n.stop().move(n.current+1)};this.prev=function(){return n.stop().move(n.current-1)};this.dots=function(){var t='<ol class="dots">';e.each(this.items,function(e){t+='<li class="dot'+(e<1?" active":"")+'">'+(e+1)+"</li>"});t+="</ol>";this.el.addClass("has-dots").append(t).find(".dot").click(function(){n.move(e(this).index())})}};e.fn.unslider=function(t){var r=this.length;return this.each(function(i){var s=e(this);var u=(new n).init(s,t);s.data("unslider"+(r>1?"-"+(i+1):""),u)})}})(window.jQuery,false)

具体用法：

引入js：

如：<script src="jquery-1.11.1.min.js"></script>
<script src="unslider.min.js"></script>

html代码：

<div class="banner" >

    <ul>

        <li>This is a slide.</li>

        <li>This is another slide.</li>

        <li>This is a final slide.</li>

    </ul>


</div>

css代码：

.banner { position: relative; overflow: auto; text-align: center;}

.banner li { list-style: none; }

.banner ul li { float: left; }

js代码：

$(document).ready(function(e) {

    $('.banner').unslider();

});

这是最简单的例子
