有人用过Yahoo Menu么

Question

可以指定一个Div New这个Menu
然后Menu.show
可是当我的Div里面的内容改变了
我怎么样让菜单重新获取内容并且显示呢？或者给个其他的例子我发现用下面这种数据结构可以重画菜单
可是我自己构造不出这样的结构(javascript太菜了)
请问大虾们我要循环构造下面的这个数组怎么写啊?
不知道我说清楚了不？
var aItems = [
                
                    { text: "Communication", submenu: { id: "communication", itemdata: [

Answer 1

我是这样构造的。肯定不对了
我只是想解释清楚我构造的意思
  var menuItems = new Array();
  var menuItem;
  var menus = new Array();
  var menu;
  for(var i=0;i<columns.length;i++)
  {
   if(columns[i].selectSingleNode("visible").text == "none")
   {
   //alert("one more");
   menuItem = {text:"",url:""};
   //alert("1");
   menuItem.text = columns[i].selectSingleNode("columnValue").text;
   menuItem.url = "javascript:setVisible('"+columns[i].selectSingleNode("columnId").text+"')";
   //alert("1");
   menuItems[menuItems.length] = menuItem;
   }
  }
  //alert("1");
  menu = {text:"",submenu:{id:"1",itemData:""}}
  menu.text = "ColumnPicker";
  menu.submenu.id = "ColumnPicker";
  menu.submenu.itemData = menuItems;
  menus[0] = menu;
  var oProductsServicesMenu = new YAHOO.widget.Menu("columnPicker");
  oProductsServicesMenu.addItems(menu);
  oProductsServicesMenu.render(document.body);
    
  oProductsServicesMenu.show();
