你好傢伙我怎樣才能讓父母「li
」突出顯示背景或在下拉導航菜單中給某個類提供一些來自CSS的屬性?菜單被訪問?類似的東西會指示它正在導航的菜單的哪個部分,並且背景保持高亮直到改變菜單。當子菜單被加入時,保持父li高亮
HTML
<ul id="menu">
<li><a href="#">About </a></li>
<li><a href="#">Programmes</a>
<ul class="secondLevel">
<li><a onClick="ajaxCall();" href="">Undergraduate</a></li>
<li><a href="#">Postgraduate</a></li>
</ul>
</li>
<li><a href="#">Academics</a></li>
<li><a href="#">Research</a></li>
<li><a href="#">Facilities</a></li>

你可以提供你的意思的例子嗎?我仍然有點困惑。 – chockleyc
當你點擊一個子菜單時會發生什麼?它是否加載另一個頁面? – Alvaro
@chockleyc http://craigsworks.com/projects/qtip2/demos/#imagemap你在左邊看到菜單,當選擇一個部分時,如何保持不同的背景,我想要類似的東西,但在我的情況下,我希望即使在一個子菜單被接受。 – BurebistaRuler
