上下滚动的js效果如下图所示:
结构代码:
<div class="scrollbox"> <div id="scrollDiv"> <ul> <li><h3><a href="#" class="linktit">移动娱乐业务突飞</a></h3> <div>为了探索推进公车改革后,新能源汽车分时租赁项目试点工作,并成立了试点工作小组... </div></li> <li><h3><a href="#" class="linktit">不停转动向上滚动可控制向上向下滚动特效</a></h3> <div>DIV 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... </div></li> <li><h3><a href="#" class="linktit">全国涂料总产量呈现直线下滑态势</a></h3> <div>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... </div></li> <li><h3><a href="#" class="linktit">镂空渔网超吸睛</a></h3> <div>镂空罩衫,短短的版型穿起来显高又俏皮,内搭长款连衣裙,非常大方哦... </div></li> <li><h3><a href="#" class="linktit">主题创业街亮相</a></h3> <div>目前已有包括咖啡厅、酒吧、餐厅、瑜伽室在内的8家商铺入驻该火车... </div></li> </ul> </div> <div class="scroltit"><div class="updown" id="but_down">向上</div><div class="updown" id="but_up">向下</div></div> </div>
样式代码:
<style type="text/css"> body{ color:#333; font-size:13px;} h3 ul li{margin:0;padding:0; list-style:none;} .scrollbox{ width: 340px; margin: 0 auto; overflow: hidden; border: 1px solid #CFCFCF; padding: 10px; } #scrollDiv{width:340px;height:359px; overflow:hidden;}/*这里的高度和超出隐藏是必须的*/ #scrollDiv li{height:90px; width:300px; padding:0 20px;background:url(ico-4.gif) no-repeat 10px 23px; overflow:hidden; vertical-align:bottom; zoom:1; border-bottom:#B7B7B7 dashed 1px;} #scrollDiv li h3{ height:24px; padding-top:13px; font-size:14px; color:#353535; line-height:24px; width:300px;} #scrollDiv li h3 a{color:#353535; text-decoration:none}#scrollDiv li h3 a:hover{ color:#F00} #scrollDiv li div{ height:36px; width:300px; color:#416A7F; line-height:18px; overflow:hidden} #scrollDiv li div a{ color:#416A7F; text-decoration:none} .scroltit{ height:26px; line-height:26px; padding-bottom:4px; margin-bottom:4px;} .scroltit h3{ width:100px; float:left;} .scroltit .updown{float:right; width:32px; height:22px; margin-left:4px} #but_up{ background:url(images/up.gif) no-repeat 0 0; text-indent:-9999px} #but_down{ background:url(images/down.gif) no-repeat 0 0; text-indent:-9999px} </style>
js引用代码:
<script src="https://img.aigexing.comjs/jquery-1.4.4.min.js" type="text/javascript"></script> <script src="https://img.aigexing.comjs/jq_scroll.js" type="text/javascript"></script> <script type="text/javascript"> $(document).ready(function(){ $("#scrollDiv").Scroll({up:"but_up" down:"but_down"}); }); </script>
滚动的js代码:
/* jQ向上滚动带上下翻页按钮 */ (function($){ $.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 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({ marginTop:upHeight } speed function(){ for(i=1;i<=line;i ){ _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:upHeight}); _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);
