将鼠标悬停在文本列表上时,需要帮助更改图像。我在这里浏览了几个示例,但仍然无法正常工作。有人可以看一下我的代码,弄清楚我在做什么错吗?

最佳答案
因为您无法使用CSS遍历祖先,而您的图片持有者就是这种方式,所以您需要使用一些JavaScript来处理此问题。这是一个基于您提供的代码的简化示例。这使用jQuery(因为我很懒),但是如果不使用普通ole javascript,也可以实现它。
$("ul a").hover(function() {
$("#pic").removeClass().addClass($(this).attr('rel'));
});
#pic{
width: 120px;
height: 120px;
border: 1px solid black;
margin-right: 20px;
float:left;
}
#pic.p1 {
background-image: url("http://fillmurray.com/200/300");
}
#pic.p2 {
background-image: url("http://fillmurray.com/200/200");
}
#pic.p3 {
background-image: url("http://fillmurray.com/300/300");
}
#pic.p4 {
background-image: url("http://fillmurray.com/120/120");
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="pic"></div>
<ul>
<li><a href="#" rel="p1">Marine Construction</a></li>
<li><a href="#" rel="p2">Offshore Construction</a></li>
<li><a href="#" rel="p3">Pipe Fabrication</a></li>
<li><a href="#" rel="p4">Onshore Construction</a></li>
</ul>
