码前课-前端必修课-html5 css3实现字幕滚动的效果

687 05-11

html5中marquee逐渐被取代，要实现字幕的滚动可以再js中实现：

<!DOCTYPE html>
<html>
<head> 
<meta charset="utf-8"> 
<title>html5</title> 
<style>
body { 
    margin: 0px; 
    font-size: 12px; 
    color: #938C43; 
    line-height: 150%; 
    text-align:center; 
} 
a:link{color: #9D943A;font-size:12px;} 
a:hover{color: #FF3300;font-size:12px;} 
a:visited{color: #9D943A;font-size:12px;} 
a.red:link{color: #ff0000;font-size:12px;} 
a.red:hover{color: #ff0000;font-size:12px;} 
a.red:visited{color: #ff0000;font-size:12px;} 
#marqueeBox{background:#f7f7f7;border:1px solid silver;padding:1px;text-align:center;margin:0 auto;} 
--> 
</style> 
</head> 

<body> 
<h4>滚动新闻</h4> 
<script language="JavaScript" type="text/javascript"> 
var marqueeContent=new Array(); 
marqueeContent[0]="<a href=http://xyq.163.com/news/2006/11/2-2-20061102170913.html target=_blank>用快速取回帐号密码</a>"; 
marqueeContent[1]="<a href=http://ekey.163.com/ target=_blank>网易将军令官方网站</a>"; 
marqueeContent[2]="<a href=http://xyq.163.com/download/wallpaper.htm target=_blank>最新壁纸下载</a>"; 
marqueeContent[3]="<a href=http://xyq.163.com/download/around.htm target=_blank>最新屏保下载</a>"; 
var marqueeInterval=new Array(); 
var marqueeId=0; 
var marqueeDelay=2000; 
var marqueeHeight=20; 
function initMarquee() { 
    var str=marqueeContent[0]; 
    document.write('<div id="marqueeBox" style="overflow:hidden;width:250px;height:'+marqueeHeight+'px" οnmοuseοver="clearInterval(marqueeInterval[0])" οnmοuseοut="marqueeInterval[0]=setInterval(\'startMarquee()\',marqueeDelay)"><div>'+str+'</div></div>'); 
    marqueeId++; 
    marqueeInterval[0]=setInterval("startMarquee()",marqueeDelay); 
} 
function startMarquee() { 
    var str=marqueeContent[marqueeId]; 
    marqueeId++; 
    if(marqueeId>=marqueeContent.length) marqueeId=0; 
    if(document.getElementById("marqueeBox").childNodes.length==1) { 
    var nextLine=document.createElement('DIV'); 
    nextLine.innerHTML=str; 
    document.getElementById("marqueeBox").appendChild(nextLine); 
    } 
    else { 
        document.getElementById("marqueeBox").childNodes[0].innerHTML=str; 
        document.getElementById("marqueeBox").appendChild(document.getElementById("marqueeBox").childNodes[0]); 
        document.getElementById("marqueeBox").scrollTop=0; 
    } 
    clearInterval(marqueeInterval[1]); 
    marqueeInterval[1]=setInterval("scrollMarquee()",20); 
} 
function scrollMarquee() { 
    document.getElementById("marqueeBox").scrollTop++; 
    if(document.getElementById("marqueeBox").scrollTop%marqueeHeight==(marqueeHeight-1)){ 
    clearInterval(marqueeInterval[1]); 
    } 
} 
initMarquee(); 
</script> 

</body>
</html>

也可以用css3实现：


 <!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>无标题文档</title>
<style>
@keyframes move
{
    0%
    {
        transform:translateY(0px);
    }
50%
    {
        transform:translateY(-200px);
    }
    100%
    {
        transform:translateY(0px);
    }
}
.picTab{height:500px;border:2px solid #000; margin:50px auto;overflow:hidden;}
.picTab .topDiv{width:1000px;height:500px; animation:move 5s linear infinite;text-align:center;}
.picTab div {margin:5px;color:black;  }


</style>
</head>
<body>
<DIV class="picTab">
<div  class="topDiv">
<div>"控制洗衣机"</div>
<div>"控制冰箱"</div>
<div>"开启洗衣机"</div>
<div>"开始洗衣"</div>
<div>"关闭洗衣机"</div>
<div>"棉麻洗"</div>
<div>"洗涤时间设为20分钟"</div>
<div>"漂洗2次"</div>
<div>"脱水6分钟"</div>
<div>"冰箱设为速冷模式"</div>
<div>"冷藏室温度设为5度"</div>
<div>"天气"</div>

</div>





</DIV>
</body>
</html>
