參數(shù)說明:
var scrollPic = new ScrollPic(); //定義變量,并初始化方法
scrollContId //滾動(dòng)容器的ID
arrLeftId //左按鈕ID
arrRightId //右按鈕ID
frameWidth //顯示框?qū)挾?br />
pageWidth //翻頁寬度
speed //移動(dòng)速度(單位毫秒,越小越快)
space //每次移動(dòng)像素(單位px,越大越快)
autoPlay //自動(dòng)播放
autoPlayTime //自動(dòng)播放間隔時(shí)間(秒)
initialize() //初始化
