Question

所以我正在尝试学习YUI工具包，而且我的菜单栏有可用的子菜单问题。如果我使用以下代码：

<html>
<head>

<!-- Google Gears -->
<script type="text/javascript" src="js/gears_init.js"></script>

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


<style type="text/css"> 

.yuimenubaritemlabel {
  margin: 0px; 
  padding: 2px; 
}
</style> 

<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') );

};

我无法使用任何一种语法来使用子菜单：

 var menuData = [ 
      {text: "File", 
       itemdata: [ "New", "Open", "Close" ] } 
      {text: "Help" 
       itemdata: [ "Welcome", "About" ] } 
     ];

或

 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。

对于将来可能会找到此页面的任何人，可以在此处找到有关如何在YUI布局中使用MenuBar模块的说明：

嘿，克里斯。很高兴看到一位老同事出现在互联网上。

只是想建议你在YUILibrary论坛上发帖 - http://yuilibrary.com/forum/（具体在这里：http://yuilibrary.com/forum/viewforum.php?f=89）。这是在Todd（编写Menu）和其他每天使用YUI的人面前获得它的最佳位置。
