我被这件事难住了。我试图将 position:relative 和各种 z-index 放入无济于事。下面是我的简单下拉菜单代码。它在除 IE 之外的所有浏览器中都能正常工作。
html页面:
<div id="nav">
<ul id="navul">
<li id="rootHome">
<ul id="Home"></ul><a href="index.php"><img src="images/LA-icon.png" style=
"height: 40px;" id="home" /></a>
</li>
<li id="rootProducts" onclick="showMenu(this)">Products
<ul id="Products">
<li>
<p class="navLink" onclick="changePage('products-1.php')">Product 1</p>
</li>
<li>
<p class="navLink" onclick="changePage('products-2.php')">Product 2</p>
</li>
<li>
<p class="navLink" onclick="changePage('products-3.php')">Product 3</p>
</li>
</ul>
</li>
<li id="rootNews">
<a href="#Link for news" class="navLink">News</a>
</li>
<li id="rootCompany" onclick="showMenu(this)">Company ∨
<ul id="Company">
<li>
<p class="navLink" onclick="changePage('./company-aboutUs.php')">About Us</p>
</li>
<li>
<p class="navLink" onclick="changePage('./company-contactUs.php')">Contact
Us</p>
</li>
</ul>
</li>
</ul>
