Flex menubar导航栏加载moudels

用menubar做的顶级菜单，怎么点击菜单然后加载一个moudels进来？

Answer 1

<!-- 系统菜单 -->
<mx:MenuBar id="menu" right="10" labelField="modName"
itemClick="loadModule(event)"
/>

<!-- 模块组件 -->
<s:ModuleLoader id="modLoader" top="30" bottom="0" left="0" right="0"
ready="onModuleLoaded()"/>

/**
* 单击菜单项，加载模块
*/
protected function loadModule(event:MenuEvent):void
{
object=null;
pickHangObject = null;
var modId:int = event.item.modId;
if(modId == -100) {
return logout();
}
var modType:int = event.item.modType;
var modUrl:String = event.item.modUrl;
// 如果是模块，则用ModuleLoader加载
if(modType == 1 &&　currentUrl != modUrl){
loading.visible = true;
var mod:Module = Module(modLoader.child);
// 如果模块有定义挂起函数，则使旧模块的挂起，用以切换新的模块
if(mod && mod.hasOwnProperty("suspend")) {
mod["suspend"].call();
}
modLoader.unloadModule();
modLoader.loadModule(modUrl);
currentUrl = modUrl;
}
// 如果是组件，则用PopUpManager加载
else if(modType == 2) {
var c:Class = getDefinitionByName(modUrl) as Class;
var x:IFlexDisplayObject = PopUpManager.createPopUp(this, c);
PopUpManager.centerPopUp(x);
}

}
