360°产品展现

Circlr是一款能够对产品图片进行360度全方位旋转展现的插件。Circlr经过按必定角度规律拍摄的产品图片，制做出可使用鼠标拖动、鼠标滚轮和移动触摸来进行图片逐帧旋转的效果。比先前的Rollerblade，动画顺畅了许多，也更易于控制，该插件很是适合于商品的展现。它的特色有：
一、支持水平或垂直方向旋转。
二、支持移动触摸事件。
三、支持滚动事件。
四、图片预加载处理。
五、能够反向和循环旋转图片。

circle插件的运用很简单：
var crl = circlr(element, options);
// element：放置图片的容器元素的ID。
// options：参数对象。
配置参数
mouse：是否经过鼠标进行图片旋转，默认值为true。
scroll：是否经过scroll进行图片旋转，默认值为false。
vertical：是否在垂直方向上移动鼠标时旋转图片，默认值为false。
reverse：是否反转方向，默认值为false。
cycle：是否循环旋转图片，默认值为true。
start：开始动画帧，默认值为0。
speed：动画帧经过circlr.turn(i)切换的速度，默认值为50毫秒。
autoplay：是否自动进行图片360度旋转播放，默认值为false。
playSpeed：动画序列的播放速度，默认值为100毫秒。
loader：预加载DOM元素的ID。
ready：图片加载完成后的回调函数。
change：动画帧改编以后的回调函数（以当前帧和总帧数为参数）。
方法
crl.el：返回对象的DOM元素节点。
crl.length：返回对象的总的动画帧数。
crl.turn(i)：动画旋转到第i帧。
crl.go(i)：动画跳转到第i帧。
crl.play()：开始动画序列的播放。
crl.stop()：中止动画播放。
crl.hide()：隐藏对象的DOM元素节点。
crl.show()：显示对象的DOM元素节点。
crl.set(options)：在插件初始化以后改变对象的参数：vertical 、reverse、cycle、speed、playSpeed
