js控制导航菜单点击后的css效果

wjx0109 2012-06-12 03:20:52

问题是这样的，我在网上找了一个二级导航菜单，鼠标移动到菜单上的效果没问题，可是点击后进入链接导航有恢复初始状态了，我想让导航一直停留在导航进入的这个页面。

就是如图所示进入“中文域名”页面之后导航一直停留在这种鼠标经过的状态，如果鼠标再在导航上其它位置滑过，效果也会跟着过去，但是鼠标离开导航之后效果还是回到当前页面鼠标停在相对导航上的位置，这样的效果，是应该有个js控制吧？应该怎么写呢？谢谢
导航代码如下：



<style>

body {

	margin-left: 0px;

	margin-top: 0px;

	margin-right: 0px;

	margin-bottom: 0px;

}

a:link {

	text-decoration: none;

}

a:visited {

	text-decoration: none;

}

a:hover {

	text-decoration: none;

}

a:active {

	text-decoration: none;

}
