Answer 1

试试这个：

CSS

.container { width: 600px; background: #ccc; } 
.ticker { white-space: nowrap; } 

HTML

<div class="container"> 
<span class="ticker">Some short text that isn't greater than the browser window</span> 
<span class="ticker">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed facilisis metus quis augue facilisis elementum. Pellentesque aliquet congue tristique. Phasellus feugiat cursus lobortis. Cras et massa odio, et vehicula nisi. Donec adipiscing condimentum diam sed hendrerit. Curabitur eros elit, aliquet et aliquam id, facilisis id nisi. Vivamus dictum commodo libero, eu venenatis nulla sodales in. Maecenas rhoncus, dui at sollicitudin scelerisque, neque lectus viverra metus, vel elementum nisl ante quis mi. Cras sagittis enim ac arcu scelerisque tristique vel in dolor. Class aptent taciti sociosqu ad litora torquent per conubia nostra, per inceptos himenaeos. Cras vehicula leo vel lacus blandit ut adipiscing lorem sodales.Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed facilisis metus quis augue facilisis elementum.

Maecenas sit amet turpis magna. Phasellus posuere mi nec nisi sodales non dapibus nibh faucibus. Vestibulum leo tellus, blandit sed auctor id, faucibus quis sem. Sed at purus quam. Praesent eget ante sem, a scelerisque nulla. Praesent id quam sit amet eros viverra euismod. Integer volutpat vulputate aliquam. Aliquam convallis dolor tellus, in cursus justo. Donec molestie consequat dolor. Nunc imperdiet arcu et justo vehicula mollis. Suspendisse id molestie velit. Morbi sed est arcu, non aliquam augue.</span> 
</div> 

脚本

$(document).ready(function(){ 
var tickerWidth = '100%'; // add '%' or 'px' to this variable 
var tickerSpeed = 10; // 0 = stopped, 30 = almost too fast 
var tickerDelay = 0; // delay in ms 
var tickerDirection = 'left'; // options = left, right (up & down work as well, but not the way you want) 
var tickerMouseoverPause = true; 
var tickerLoopTimes = 0; // 0 = infinite # of loops 

$('.ticker').each(function(){ 
    if ($(this).width() > $(this).parent().width()) { 
    var marq = $('<marquee></marquee>').attr({ 
    'behavior' : 'scroll', 
    'scrollamount' : tickerSpeed, 
    'direction' : tickerDirection, 
    'width' : tickerWidth 
    }) 
    if (tickerLoopTimes != 0) { 
    marq.attr('loop', tickerLoopTimes) 
    } 
    if (tickerMouseoverPause) { 
    marq.attr({ 
    'onmouseover' : 'this.stop()', 
    'onmouseout' : 'this.start()' 
    }) 
    } 
    $(this).wrap(marq); 
    } 
}) 
}) 

这个脚本基本上包装了一个<marquee>文本，得到它的属性的更多信息请查看this site。

注意我尝试使用不显眼的jQuery为此，在选取框上使用hover，但它不起作用。但添加内联mouseover和mouseout事件到标签工作得很好。
