This time I will bring you jQuery to make images scroll and fade in and out. What are the precautions for jQuery to make images scroll and fade in and out? The following is a practical case, let’s take a look.
向上滚动代码带上下翻按钮滚动特效 特效效果如下:
p CSS JS自动不断向上一个一个滚动可控制向上向下滚动特效...
我国涂料工业将面临涂料消费税征收全面铺开,环保压力持续增加,2015年的形势不容乐观...

向上
向下
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 = $("#"+ opt.up);//Shawphy:向上按钮 var _btnDown = $("#"+ opt.down);//Shawphy:向下按钮 var timerID; var _this=this.eq(0).find("ul:first"); var lineH=_this.find("li:first").height(), //获取行高,此处行高固定但是当文字伟一行或者两行时,要动态获取吧?? line=opt.line?parseInt(opt.line,10):parseInt(this.height()/lineH,10), //每次滚动的行数,默认为一屏,即父容器高度 speed=opt.speed?parseInt(opt.speed,10):500; //卷动速度,数值越大,速度越慢(毫秒) timer=opt.timer //?parseInt(opt.timer,10):3000; //滚动的时间间隔(毫秒) if(line==0) line=1; var upHeight=0-line*lineH; //滚动函数 var scrollUp=function(){ _btnUp.unbind("click",scrollUp); //Shawphy:取消向上按钮的函数绑定 _this.animate({ //当滚动的元素height为max-height时,实时获取元素height marginTop:-_this.find("li:first").height() },speed,function(){ // for(i=1;i<=line;i++){ // _this.find("li:first").appendTo(_this); // } _this.find("li:first").appendTo(_this); _this.css({marginTop:0}); _btnUp.bind("click",scrollUp); //Shawphy:绑定向上按钮的点击事件 }); } //Shawphy:向下翻页函数 var scrollDown=function(){ _btnDown.unbind("click",scrollDown); for(i=1;i<=line;i++){ _this.find("li:last").show().prependTo(_this); } _this.css({marginTop:-_this.find("li:first").height()}); _this.animate({ marginTop:0 },speed,function(){ _btnDown.bind("click",scrollDown); }); } //Shawphy:自动播放 var autoPlay = function(){ if(timer)timerID = window.setInterval(scrollUp,timer); }; var autoStop = function(){ if(timer)window.clearInterval(timerID); }; //鼠标事件绑定 _this.hover(autoStop,autoPlay).mouseout(); _btnUp.css("cursor","pointer").click( scrollUp ).hover(autoStop,autoPlay);//Shawphy:向上向下鼠标事件绑定 _btnDown.css("cursor","pointer").click( scrollDown ).hover(autoStop,autoPlay); } }) })(jQuery);
Add another copy, the deleted script
/* jQ向上滚动带上下翻页按钮 */ (function($){ $.fn.extend({ txtScroll: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"); 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):2000; //滚动的时间间隔(毫秒) //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(){ _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); _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) setIntervalT = window.setInterval(scrollUp,timer); }; var autoStop = function(){ if(timer)window.clearInterval(setIntervalT); }; //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);
The running effect is as follows:
