下面是jq插件源码
/*
jQ向上滚动带上下翻页按钮
*/
(function($){
$.fn.extend({
Scroll:function(opt,callback){
//参数初始化
if(!opt) var opt={};
var _btnUp = $("#"+ opt.up);//Shawphy:向上按钮
var _btnDown = $("#"+ opt.down);//Shawphy:向下按钮
var timerID;
var _this=this.eq(0).find("ul:first");
var lineH=_this.find("li:first").height(), //获取行高,此处行高固定但是当文字伟一行或者两行时，要动态获取吧？？
