jq实现广告栏单行或者多行上下无缝接滚动

H5实现广告栏之类的文字上下滚动，展示的效果为同时显示多行数据，然后首尾无缝连接，时间间隔为一秒滚动一次，延迟一秒钟，这些都是可配的参数；

html如下：

<div id="news_container">
     <ul>
	<li>1某某某 抽中了100元话费券</li>
	<li>2某某元话费券</li>
	<li>3某某某 抽中了100元话费券</li>
	<li>4某某某 抽中了10元话费券</li>
	<li>1某某某 抽中费券</li>
	<li>2某某某 抽中了100元话费券</li>
	<li>3某中了100元话费券</li>
	<li>4某某某 抽中了10费券</li>
     </ul>
</div>

 css如下：

#news_container{
	 100%;
	padding: 0 20px;
}
.drawList li{
	text-align: center;
	color:#993300;
	font-size: 12px;
	line-height: 17px;
	 calc(87.2vw - 40px);
	display: block !important;
}

 js如下：

$('#news_container').vTicker({
	speed: 1000,    //速度
	pause: 1000,    //延迟
	animation: 'fade',
	mousePause: false,
	showItems: 3    //展示行数
});    

 引入jq以及vticker

下面呈上vticker源文件

/*
* vertical news ticker
* Tadas Juozapaitis ( kasp3rito@gmail.com )
* http://plugins.jquery.com/project/vTicker
*/
(function(a){a.fn.vTicker=function(b){var c={speed:700,pause:4000,showItems:3,animation:"",mousePause:true,isPaused:false,direction:"up",height:0};var b=a.extend(c,b);moveUp=function(g,d,e){if(e.isPaused){return}var f=g.children("ul");var h=f.children("li:first").clone(true);if(e.height>0){d=f.children("li:first").height()}f.animate({top:"-="+d+"px"},e.speed,function(){a(this).children("li:first").remove();a(this).css("top","0px")});if(e.animation=="fade"){f.children("li:first").fadeOut(e.speed);if(e.height==0){f.children("li:eq("+e.showItems+")").hide().fadeIn(e.speed)}}h.appendTo(f)};moveDown=function(g,d,e){if(e.isPaused){return}var f=g.children("ul");var h=f.children("li:last").clone(true);if(e.height>0){d=f.children("li:first").height()}f.css("top","-"+d+"px").prepend(h);f.animate({top:0},e.speed,function(){a(this).children("li:last").remove()});if(e.animation=="fade"){if(e.height==0){f.children("li:eq("+e.showItems+")").fadeOut(e.speed)}f.children("li:first").hide().fadeIn(e.speed)}};return this.each(function(){var f=a(this);var e=0;f.css({overflow:"hidden",position:"relative"}).children("ul").css({position:"absolute",margin:0,padding:0}).children("li").css({margin:0,padding:0});if(b.height==0){f.children("ul").children("li").each(function(){if(a(this).height()>e){e=a(this).height()}});f.children("ul").children("li").each(function(){a(this).height(e)});f.height(e*b.showItems)}else{f.height(b.height)}var d=setInterval(function(){if(b.direction=="up"){moveUp(f,e,b)}else{moveDown(f,e,b)}},b.pause);if(b.mousePause){f.bind("mouseenter",function(){b.isPaused=true}).bind("mouseleave",function(){b.isPaused=false})}})}})(jQuery);
