在下拉菜单中显示图像

标签： javascript jquery html css

我想将鼠标悬停在下拉菜单中的列表项目上时显示图像，我不能按照我想要的方式单独使用css，我想在悬停时右侧显示图像左边的相应名称。

到目前为止我编写的代码不起作用，因为使用css时必须具有亲子关系，我很缺乏经验，所以也许解决方案非常简单，如果是这样，请原谅。< / p>

HTML：

<body>
<div class="menu-wrap">
    <nav class="menu">
        <ul class="clearfix">
            <li class="current-item"><a href="#">Home</a>
            </li>
            <li><a href="#">Collaboratori</a>                
                <div class="sub-menu-collab">
                    <div>
                         <ul class="listanomi">
                            <li><a href="#">Paolo</a></li>
                            <li><a href="#">Luca</a></li>
                            <li><a href="#">Anna</a></li>
                            <li><a href="#">Mara</a></li>
                        </ul>
                        <img class="menuimage" src="https://encrypted-tbn1.gstatic.com/images?q=tbn:ANd9GcSR6KryU6yZY04TXZ7qgzBYtX61idklEgJGxnee_MausSGZJQqvmRXEbvo" title="Paolo">

.sub-menu-collab li, .sub-menu-mat li, .sub-menu-arte li {

    text-decoration: none;
}

.sub-menu-collab li a, .sub-menu-mat li a, .sub-menu-arte li a {

你犯了两个错误：

  1. 在css中使用父子关系时，您需要将此案例中`locale1` => [ 'domain1' => [ 'key1-1' => 'value1-1', 'key1-2' => 'value1-2' ], 'domain2' => [ ... ] ] 元素的子项指向父级。

    2. img

    1. CSS选择应该是

      <li> <a href="#">Anna</a> <img class="menuimage" src="https://encrypted-tbn1.gstatic.com/images?q=tbn:ANd9GcSR6KryU6yZY04TXZ7qgzBYtX61idklEgJGxnee_MausSGZJQqvmRXEbvo" title="Anna"> </li>

      2. .menu .listanomi > li:hover .menuimage { opacity: 1; }不是.listanomi的直接子女。

      注意：我还将img float更改为绝对到右上角。

      此处的工作示例： 

      .menu
      .clearfix:after {
  display: block;
  clear: both;
}

}
.menuimage {

如果要显示与标题对应的图像，可以使用jQuery作为示例：

$(".item").hover(function() {
   $(".menuimage[title='"+$(this).html()+"']").css("opacity", 1);
  }, function() {
    $(".menuimage[title='"+$(this).html()+"']").css("opacity", 0);
});
