代碼說明
1.我的CSS分割為2段了，第一段為此演視用，可自己定制，第二段為此框架必須。
2.script我也分割為2段，第一段為必須，第二段為客戶定制的，我這里的代碼是給一個實現參考。
3.以下的HTML代碼為參考實現的必須容器代碼

復制代碼代碼如下:

<ul id="itemsPanel"> 
</ul> 
<div id="cardContent"> 
    <iframe id="cardFrame"> 
    </iframe> 
</div>

使用介紹:
1.ItemsPanel對象
   構造方法：new Asgard.CardProgram.ItemsPanel("itemsPanel","cardFrame").
   接受的2個參數，第一個為ul容器ID，第二個為我們需要展現標簽對應的內容的irame的ID 。
   ItemPanel對象使用addItem方法添加Item。
   如果你需要創建多個ItemsPanel，可以自己參考我的范例來進行。
2.Item對象
   構造方法：new Asgard.CardProgram.Item("index","時空創意","http://www.skst.com.cn",true)接受4個參數
   第一個為打算創建的選項卡的id，第二個為打算創建的選項卡的標題，第三個為此選項卡對應的URL，第四個為是否為首頁，因為我們也許會打算創建一個默認頁面不允許關閉。當然如果你全部設置為true，那么也就是正常的選項卡效果了。
