下面的例子示范了动态加载另一个css文件
//loadCssPage.html
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<link id="loadCss" type="text/css" rel="stylesheet" href="bj.css"/>
<title>无标题文档</title>
<script type="text/javascript">
function loadCss(){
var cssTag = document.getElementById('loadCss');
var head = document.getElementsByTagName('head').item(0);
if(cssTag) head.removeChild(cssTag);
css = document.createElement('link');
css.href = "bj2.css";
css.rel = 'stylesheet';
css.type = 'text/css';
css.id = 'loadCss';
head.appendChild(css);
}
loadCss();
</script>
</head>
<body class="bg">
</body>
</html>
//bg.css
.bg{
background:#003399;
}
//bg2.css
.bg{
background:#00CC66;
}
