• 支持桌面裝置與行動裝置

• 支援多個 Banner 顯示(不用擔心太多時的記憶體問題, DOM UI 有回收)

• 有漸變、隨機、滑動的呈現方式

• 可以設定任意寬高或滿版

• 滿版的寬度支持行動裝置轉動自適應寬度

• 可以自定義 data attribute 處理 event callback

• 向下相容? 2018 年了誰管這個東西拉

• resize([width], [height])

可以重新設定寬高, 一定得用在呼叫 init() 之後

width	String	option	resize banner width	'600px'
height	String	option	resize banner height	'200px'
