  • JavaScript实现竖直文本滚动

    一、HTML代码

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head>
    	<meta http-equiv="content-type" content="text/html;charset=utf-8">
    	<title>Scroll Text</title>
    	<link rel="stylesheet" type="text/css" href="scrollText.css">
    
    </head>
    <body>
    	<div class="news_root">
    		<div class="news_header">HeaderLine</div>
    		<div id="scrollContainer">
    			<div id="scrollContent">
    				<a href="#">w3c has released html5</a>
    				<a href="#">w3c has released css3</a>
    				<a href="#">w3c has released ecmasript5</a>
    				<a href="#">w3c has released ria</a>
    				<a href="#">w3c has released html5 bom</a>
    				<a href="#">w3c has released ria</a>
    				<a href="#">w3c has released html5 bom</a>
    			</div>
    		</div>
    	</div>
    	<script type="text/javascript" src="scrollText.js"></script>
    </body>
    </html>

    二、CSS代码

    body
    {
    	font-size:15px;
    	font-family: 'Microsoft YaHei','微软雅黑','SimSun','宋体';
    	margin: 0px;
    	padding: 0px;
    	text-align: center;
    }
    a
    {
    	color:#666666;
    	text-decoration: none;
    	display: block;
    	line-height: 1.5em;
    }
    a:hover
    {
    	color: #CC0000;
    	text-decoration: none;
    }
    .news_root
    {
    	 255px;
    	height: 134px;
    	text-align: left;
    	margin: 0 auto;
    	border: 1px solid #ccc;
    }
    .news_header
    {
    	 243px;
    	height: 16px;
    	vertical-align: top;
    	text-align: left;
    	font-size: 14px;
    	padding: 6px;
    	background-color: #ccc;
    }
    #scrollContainer
    {
    	 245px;
    	margin: 2px 5px;
    	overflow: hidden;
    	text-align: left;
    }

    三、Javascript代码

    var stopscroll = false;
    var scrollContHeight = 95;   //滚动区域的高度
    var scrollContWidth = 230;   //滚动区域的宽度
    var scrollSpeed = 25;        //滚动的速度,越小滚动越快
    
    var scrollContainer = document.getElementById("scrollContainer");
    var scrollContent = document.getElementById("scrollContent");
    do
    {
    	scrollContainer.appendChild(scrollContent.cloneNode(true));
    }while(scrollContainer.offsetHeight < scrollContHeight);
    
    scrollContainer.style.width = scrollContWidth+"px";
    scrollContainer.style.height = scrollContHeight+"px";
    scrollContainer.noWrap = true;
    
    //加入�事件:鼠标经过,停止滚动;鼠标离开,继续滚动
    scrollContainer.onmouseover = new Function("stopscroll = true");
    scrollContainer.onmouseout = new Function("stopscroll = false");
    
    function init()
    {
    	scrollContainer.scrollTop = 0;
    	setInterval(scrollUp,scrollSpeed);
    }
    init();
    
    var currTop = 0;
    function scrollUp()
    {
    	if(stopscroll == true)
    		return;
    	currTop = scrollContainer.scrollTop;
    	scrollContainer.scrollTop += 1;
    	if(currTop == scrollContainer.scrollTop)
    	{
    		scrollContainer.scrollTop = 0;
    		scrollContainer.scrollTop += 1;
    	}
    }
