Question

到目前为止，我有以下内容：

$("#main-link-bottom-about").mouseenter(function() {
    $("#main-about-hover").slideDown("slow");
});

$("#main-about-hover, #main-link-bottom-about").mouseleave(function() {
    $("#main-about-hover").slideUp("slow");
});

当您将鼠标悬停在链接上时，这基本上是一个下拉菜单。我想要实现的是，当您将鼠标悬停在#main-link-bottom-about上时，#main-about-hover会在鼠标离开#main-about-hover，#main-link-bottom-about时向上滑动。

然而，问题是，如果鼠标将#main-about-hover留在#main-link-bottom-about上，#main-about-hover会向上滑动，因为我不希望这种情况发生。

是否可以添加此异常，或者我是以错误的方式进行此操作？

一个很好的起点就是这个。使导航比示例更漂亮（将其放在每个类别下），但这将有效。

Answer 2

试试此代码

$("#main-link-bottom-about, #main-links-bottom-hover").mouseenter(function () {
  $("#main-about-hover").stop().slideDown("slow");
});

$("#main-about-hover, #main-link-bottom-about").mouseleave(function () {
  $("#main-about-hover").stop().slideUp("slow");
});

最好将链接和悬停菜单嵌套在同一个元素中。这将允许您将鼠标事件绑定到单个元素。另外，请考虑使用类而不是DOM ID，这样您就可以根据需要轻松地将悬停菜单添加到其他链接。

例如：

<强> HTML

<div id="main-links-bottom">
    <div class="main-link-container">
        <a href="index.php" class="main-infotext-bottom">About</a>
        <div class="hover-menu">
             <a href="#">Contact</a>
             <a href="#">Technology</a>
             <a href="#">Coverage</a>
             <a href="#">Environment</a>
             <a href="#">T&amp;C's</a>
             <a href="#">Refund Policy</a>
        </div>
    </div>
    <div class="main-link-container">
         <a href="#" class="main-infotext-bottom">Information</a>
    </div>
    ...
</div>

JS现在可以相当简单，甚至更简单slideToggle()：

<强>的Javascript

 $('#main-links-bottom .main-link-container').bind('mouseenter mouseleave',
      function() {
          $(this).find('.hover-menu').slideToggle('slow');
      }
 );
