java 代码

最近想用myfaces网站上的Horizontal Panel Navigation ，结果copy它的例子都不能使用。google一番，发现如下解决方案。

来源：http://www.nabble.com/Horizontal-Panel-Navigation---panelNavigation2-tf2035583.html#a5600977

能够运行的代码如下

<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>

<%@ taglib uri="http://myfaces.apache.org/tomahawk" prefix="t" %>

<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>

<html>

<head>

<!--

startList = function()

{

if (document.all && document.getElementById)

{

// *************************************************************************

// RM-comment: HERE IS THE CHANGE TO "hNav_outer" from

// *************************************************************************

navDivRoot = document.getElementById("myhNav_outer");

navRoot = navDivRoot.childNodes[0];

for (i=0; i<navRoot.childNodes.length; i++)

{

node = navRoot.childNodes[i];

if (node.nodeName=="LI")

{

node.onmouseover=function()

{

this.className+=" over";

}

node.onmouseout=function()

{

this.className=this.className.replace(" over", "");

}

window.onload=startList;

// -->

</script>

body { font-family : arial, verdana, Geneva, Arial, Helvetica, sans-serif; font-size : 14px; }

RM-comment: this is the section from the original css/basic.css file, but:

"hNav_outer got replaced by "myhNav_outer", "on" by "on2", and "off" by "off2".
