用户悬停时如何更改背景颜色？我试过这个，但它不起作用。
<select>
<option>bmw</option>
<option>audi</option>
<option>mercedes</option>
</select>
$('option').hover(function(){
$(this).css("background-color","#FFFFCC");
});

You cannot use option in this way. The best solution would be styling something similar with <ul>and <li>and interacting with JS.
您不能以这种方式使用选项。最好的解决办法是与造型类似的东西<ul>，并<li>与JS交互。

Since you already use jQuery, there is a pretty nice plugin - image-dropdown+ demo from the makers.
由于您已经使用 jQuery，因此有一个非常不错的插件 - image-dropdown+来自 makers 的演示。

hoverevent can not be bound to an optiontag. I'll update this post if I find the documentation or proof that says so. In my experience, this cannot be done.
hover事件不能绑定到option标签。如果我找到这样说的文档或证据，我会更新这篇文章。根据我的经验，这是无法做到的。
