前言:

如今你们对“jquery横向跑马灯文字”大概比较重视,兄弟们都需要知道一些“jquery横向跑马灯文字”的相关内容。那么小编也在网络上搜集了一些有关“jquery横向跑马灯文字””的相关知识,希望兄弟们能喜欢,兄弟们一起来了解一下吧!

1、代码布局html

<div id="booksMarquee" class="booksMarquee">        <ul style="width: 4438px;">                <li>            陈* 购买了不限购的,土巴兔 </li>                <li>            陈* 购买了不限购的,土巴兔 </li>                <li>          </ul></div>
2、css
//滚动效果.booksMarquee{    width:100%;    height: 30px;    background: #FFF6DF;    border-radius: 4px;    overflow:hidden;    margin-bottom: 10px;}.booksMarquee li{    float:left;//上下滚动,可以去掉浮动    font-size: 12px;    line-height:30px;    color: #FF5300;    padding:0 30px;}
3、js调用
//滚动效果,顺滑的滚动    if ($('#booksMarquee').length > 0) {      $('#booksMarquee').kxbdSuperMarquee({        isMarquee:true,        isEqual:false,        scrollDelay:20,        direction:'left'        //direction: 'left',//滚动方向,'left','right','up','down'      });    }//调用方式2:停顿2s在滚动的效果 $('#booksMarquee').kxbdSuperMarquee({   distance:40,   time:2,//停顿2s在滚动   direction:'up' });//一次滚动一屏			$('#marquee3').kxbdSuperMarquee({				distance:400,				time:4,				navId:'#mar3Nav',				direction:'left'			});				//一次滚动一屏,不自动滚动,点击滚动			$('#marquee4').kxbdSuperMarquee({				isAuto:false,				distance:186,				btnGo:{left:'#goL2',right:'#goR2'},				direction:'left'			});

附带marqueen.js
