javascript实现图片轮换动作方法 / 张生荣

图片轮换是一种相当复杂的技术，早些年基本用flash实现。这里有一个链接，教大家如何用flash实现它的。之所以用flash，是因为flash是基于帧的，这与图片轮换的原理相当接近。为了模拟帧的效果，我们要用到overflow把多余的部分遮罩掉，也就是flash中常说的遮罩层。在Flash中，连时间轴都是可视的，而我们则全凭想象力与数学来计算现在是到了哪一张图。加之，flash有Robert Penner大神的缓动公式，那实在太耀眼，直到script.aculo.us类库搞出自己的缓动公式，才扭转局面。

我们来看一看图片轮换的结构层。它应该包含框体，图片展示区，图片滑动层与分页栏。原谅我制造这么多词汇，因为没有个名词讲解就难以为继了，前人也没有做这样的总结，个个都不愿意分享一下。框体就是一个div元素，作用有两个：提供相册的边框与作为分页栏的包含块。如果不清楚什么叫包含块（containing block）的话，自己查阅CSS权威指南吧。接着下来图片展示区与图片滑动层，也就是我实现新式无缝滚动的那一种结构，一个很干净的无序列表，所有难点都转移到设置它的CSS上。至于图片展示区就是ul元素，大小为一张图片的大小；图片滑动层就是那个li元素，也只有一个li元素而已，利用CSS强制把它里面的图片不换行向左浮动，并设置li元素一个很大很大的宽度，好让它一行容纳所有图片。分页栏就是一个包含许多链接的span元素，和普通的水平菜单差不多，只不过要用绝对定位它安置到框体的右下角。

这个和我以前的系列一样，不用JS也可以点击实现切换。不过以前是用锚点来改变scrollTop的值，现在是改变scrollLeft的值。

如果不使用缓动效果，很简单。

var Rotate = function(id){
 try{document.execCommand("BackgroundImageCache", false, true);}catch(e){};
 var container = document.getElementById(id),
 slide = container.getElementsByTagName("li")[0];
 slide.innerHTML += slide.innerHTML;
 var item = slide.getElementsByTagName("a"),
 critical = item[item.length/2].offsetLeft,//临界值
 distance = critical/(item.length/2),
 delta = - distance;
 (function(){//实现自动轮换图片
  setTimeout(function(){
   delta = delta - distance;
   if(delta < -critical){
    delta = - distance;
   }
   slide.style.left = delta + "px";//★★★★★★★★
   setTimeout(arguments.callee,1500)
  },1500)
 })()
}

要使用缓动，就要动用我的缓动公式与transition函数，在星号的位置中调用。

我们也可以像第一部分那样加入一个信息栏，这样程序就拥有三个定时器了，看起来让人有点头晕，现实中不提倡这样做，这里只是试范一下如何使用transition的回调函数罢了。

//动态生成li元素并把它插入到DOM树中。
var tip = document.createElement("li");//信息栏
tip.style.cssText = "position:absolute;bottom:0;width:400px;height:40px;line-height:40px;text-indent:2em;";
slide.parentNode.appendChild(tip);
if(!+"\v1"){
 tip.style.cssText += "color:#369;background:#fff;filter:alpha(opacity=50)";
}else{
 tip.style.cssText += "color:#fff;background: rgba(164, 173, 183, .65);";
}

最后为信息栏上的按钮绑定点击事件就行了。

有的人很懒，不喜欢点击，想在按钮上一掠而过也能看到效果。这简单，我们把绑定函数独立出来，分别绑定到onclick事件与onmouseover事件上就行了。现在我们换一个缓动公式，反正这东西多着呢。比如这个pulse，像蛇信子一样来回多次振动（默认5次，有第二个参数可以自己调，我调到10次），非常有意思。你们可以试试一下子掠过所有按钮，效果是何等的炫目！
