上圖中，每個 Class 定義了一個層，在 JavaScript 及 CSS 中，對層進行操作。每個層的 Class 名稱標志了他們在菜單中的相對位置。
定義：child2、child3 和 parent 各自標志了一個層，我們稱它為“單位”（其實我也不知道準確的名稱應該是什么，姑且先這么叫吧:-)），而 child1 和 child4 則標志了處于同一相對位置的幾個子層所組成的父層，我們稱它為“集合”。
注1：原(M$)文件中引用了../Javax.htm 及 ../NAVSTYLE.CSS 兩個文件，為敘述方便，上述兩個文件中與本文有關的代碼被直接添加到本文中。
注2：原(M$)代碼中此處有一語句"window.event.cancelbubble == true;"，我沒看懂，刪了~~
注3：原(M$)代碼中條件還包含"(divColl(i).className == "child4")||"，我實在沒看明白有什么作用，刪了，有知道的大蝦還請指教；
注4：原(M$)代碼中不包含此部分代碼，我加上的，讓 parent 也能主動關閉。
最后還有一點說明，在每一個有子菜單的層上加一個語句onmouseOver="...","..."就是onClick里邊的東東，試試看，你看到了什么？
