摘要：是一款可以對產品圖片進行度全方位旋轉展示的插件。動畫幀通過切換的速度，默認值為毫秒。動畫幀改編之后的回調函數以當前幀和總幀數為參數。返回對象的總的動畫幀數。顯示對象的元素節點。

Circlr是一款可以對產品圖片進行360度全方位旋轉展示的插件。Circlr通過按一定角度規律拍攝的產品圖片，制作出可以使用鼠標拖動、鼠標滾輪和移動觸摸來進行圖片逐幀旋轉的效果。比先前的Rollerblade，動畫順暢了許多，也更易于控制，該插件非常適合于商品的展示。它的特點有：
1、支持水平或垂直方向旋轉。
2、支持移動觸摸事件。
3、支持滾動事件。
4、圖片預加載處理。
5、可以反向和循環旋轉圖片。

circle插件的運用很簡單：
var crl = circlr(element, options);
// element：放置圖片的容器元素的ID。
// options：參數對象。
配置參數
mouse：是否通過鼠標進行圖片旋轉，默認值為true。
scroll：是否通過scroll進行圖片旋轉，默認值為false。
vertical：是否在垂直方向上移動鼠標時旋轉圖片，默認值為false。
reverse：是否反轉方向，默認值為false。
cycle：是否循環旋轉圖片，默認值為true。
start：開始動畫幀，默認值為0。
speed：動畫幀通過circlr.turn(i)切換的速度，默認值為50毫秒。
autoplay：是否自動進行圖片360度旋轉播放，默認值為false。
playSpeed：動畫序列的播放速度，默認值為100毫秒。
loader：預加載DOM元素的ID。
ready：圖片加載完成后的回調函數。
change：動畫幀改編之后的回調函數（以當前幀和總幀數為參數）。
方法
crl.el：返回對象的DOM元素節點。
crl.length：返回對象的總的動畫幀數。
crl.turn(i)：動畫旋轉到第i幀。
crl.go(i)：動畫跳轉到第i幀。
crl.play()：開始動畫序列的播放。
crl.stop()：停止動畫播放。
crl.hide()：隱藏對象的DOM元素節點。
crl.show()：顯示對象的DOM元素節點。
crl.set(options)：在插件初始化之后改變對象的參數：vertical 、reverse、cycle、speed、playSpeed
