我有一個UI項目。我想交替出現的背景顏色 下面是HTML無序列表中項目的交替背景顏色
<html>
<head>
<title>JQuery Problem 1</title>
<script type="text/javascript" src="jquery-1.4.min.js"></script>
<script type="text/javascript" src="problem1.js"></script>
</head>
<body>
<ol>
<li>Comp 250
<ul>
<li>HTML</li>
<li>CSS</li>
<li>CGI</li>
<li>PHP</li>
<li>JavaScript</li>
</ul>
</li>
<li>Comp 345
<ul>
<li>Objects and classes</li>
<li>Static and constant members</li>
<li>Operator overloading</li>
<li>Templates</li>
<li>Inheritance</li>
<li>Polymorphism</li>
</ul>
</li>
<li>Comp 431
<ul>
<li>Perl language</li>
<li>File uploads and downloads</li>
<li>AJAX and JSON</li>
<li>Java Servlets</li>
<li>JSP</li>
</ul>
</li>
</ol>
</body>
</html>
這裏是馬的JQuery
$(document).ready(function()
{
$("ol > li").css({margin: "1em", fontWeight: "bold"});
$("ol li li").css({fontWeight: "normal"});
$("ul li").css('border', '1px solid white');
$("ul li").hover(function()
{
$(this).css('border', '1px solid red');
},
function()
{
$(this).css('border', '1px solid white')
});
});
現在我想交替,在UL中的第一項應始終#FDD和第二#FFD
