所以我正在尝试学习 YUI 工具包，但我的菜单栏有可用的子菜单时遇到了问题。如果我使用以下代码：

<script type="text/javascript" src="js/gears_init.js"></script>
<script type="text/javascript" src="mainpanel.js"></script>
<style type="text/css">

margin: 0px;

<script type="text/javascript">
YAHOO.util.Event.onDOMReady(function() {
makePanel();
});
</script>
</head>
<body class="yui-skin-sam"></body>
</html>
使用以下 javascript：
function makePanel() {
var Dom = YAHOO.util.Dom,
Event = YAHOO.util.Event,
MenuBarItem = YAHOO.widget.MenuBarItem;
var body = document.body;
var divNames = ['top1', 'bottom1', 'left1', 'right1', 'center1'];
for ( var i in divNames ) {
var div = document.createElement('div');
div.id = divNames[i];
div.style.border = 0;
body.appendChild(div);
}
var topDiv = document.getElementById('top1');
var layout = new YAHOO.widget.Layout({
units: [
{ position: 'top', height: 25, body: 'top1' },
{ position: 'right', header: 'Right', width: 300, resize: true, collapse: true, scroll: true, body: 'right1', animate: true},
{ position: 'bottom', height: 20, body: 'bottom1' },
{ position: 'left', header: 'Left', width: 200, body: 'left1', collapse:true},
{ position: 'center', body: 'center1'}
]
});
layout.render(document.body);
var menuData = [
{ text: "File", },
{ text: "Help", }
];
var menuBar = new YAHOO.widget.MenuBar("menubar", {
hidedelay: 750, autosubmenudisplay: true,
lazyload: true,
itemdata: menuData,
effect: {
effect: YAHOO.widget.ContainerEffect.FADE,
duration: 0.25
}
});
/*var fileMenu = menuBar.getItem(0);
if ( fileMenu != null ) {
fileMenu.addItem({ text: "Log off", id: "logoff", onclick: { fn: onLogoff } });
}*/
menuBar.render( document.getElementById('top1') );
};
我无法使用以下任一语法使子菜单工作：
var menuData = [
{text: "File",
itemdata: [ "New", "Open", "Close" ] }
{text: "Help"
itemdata: [ "Welcome", "About" ] }
];
或者
var menuData = [
{ text: "File",
submenu: {
id: "filemenu",
itemdata: [ "New", "Open", "Close" ] }
} ];
关于我哪里出错的任何想法？我正在使用 YUI 2.0。
