function $(_0){
        return document.getElementById(_0);

        if ($(tableName).style.display=="none"){

    }    

放在<body>…</body>之間:(item)
<div class="item"> 
 <a href="javascript:popmenu('DetailItem1','item1');" id="item1">
 <img src="img/close.gif" border="0"> Item</a>
</div>

放在<body>…</body>之間:(detailItem)
 <div class="detailItem"  id="DetailItem1" style="display:none;"> 
  ‧<a href="#">DetailItem01</a> 
  ‧<a href="#">DetailItem02</a> 
  ‧<a href="#">DetailItem03</a>
 </div>

  範例中只作了一層,若要多層,只要更改<a href="javascript:popmenu(‘DetailItem2′,’item2’);" id="item2"><div class="detailItem" id="DetailItem2" style="display:none;">即可,依此類推,但勿必注意到item2的id="item2",DetailItem2的 id="DetailItem2"兩兩一組,名稱要一樣。
