The following is the jq plug-in source code

/* 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 = $("//m.sbmmt.com/m/#"+ opt.up);//Shawphy:向上按钮 var _btnDown = $("//m.sbmmt.com/m/#"+ 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？？ line=opt.line?parseInt(opt.line,10):parseInt(this.height()/lineH,10), //每次滚动的行数，默认为一屏，即父容器高度 speed=opt.speed?parseInt(opt.speed,10):500; //卷动速度，数值越大，速度越慢（毫秒） timer=opt.timer //?parseInt(opt.timer,10):3000; //滚动的时间间隔（毫秒） if(line==0) line=1; var upHeight=0-line*lineH; //滚动函数 var scrollUp=function(){ _btnUp.unbind("click",scrollUp); //Shawphy:取消向上按钮的函数绑定 _this.animate({ //当滚动的元素height为max-height时，实时获取元素height marginTop:-_this.find("li:first").height() },speed,function(){ // for(i=1;i<=line;i++){ // _this.find("li:first").appendTo(_this); // } _this.find("li:first").appendTo(_this); _this.css({marginTop:0}); _btnUp.bind("click",scrollUp); //Shawphy:绑定向上按钮的点击事件 }); } //Shawphy:向下翻页函数 var scrollDown=function(){ _btnDown.unbind("click",scrollDown); for(i=1;i<=line;i++){ _this.find("li:last").show().prependTo(_this); } _this.css({marginTop:-_this.find("li:first").height()}); _this.animate({ marginTop:0 },speed,function(){ _btnDown.bind("click",scrollDown); }); } //Shawphy:自动播放 var autoPlay = function(){ if(timer)timerID = window.setInterval(scrollUp,timer); }; var autoStop = function(){ if(timer)window.clearInterval(timerID); }; //鼠标事件绑定 _this.hover(autoStop,autoPlay).mouseout(); _btnUp.css("cursor","pointer").click( scrollUp ).hover(autoStop,autoPlay);//Shawphy:向上向下鼠标事件绑定 _btnDown.css("cursor","pointer").click( scrollDown ).hover(autoStop,autoPlay); } }) })(jQuery);
