悬停李和第二李元素

Question

我有一个导航菜单，它在psuedo之前，如果我将我的li元素悬停，我想要更改当前li和li之后的属性

.cruise-turlari .cruise-box .cruise-list-box ul li:after {
  content: "";
  width: 86%;
  display: block;
  margin: 0 auto;
  height: 1px;
  background: #cbcbcb;
}
.cruise-turlari .cruise-box .cruise-list-box ul li a {
  display: block;
  color: #000;
  font-size: 14px;
  padding: 7px 33px;
  -webkit-transition: all linear 0.4s;
  -moz-transition: all linear 0.4s;
  transition: all linear 0.4s;
}
.cruise-turlari .cruise-box .cruise-list-box ul li a:hover {
  background: #000;
  color: #FFF;
}

<div class="cruise-list-box">
  <ul>
    <li><a href="#">Vizesiz Yunan Adaları İzmir Hareket <i class="fa fa-chevron-right"></i></a>
    </li>
    <li><a href="#">Vizesiz Yunan Adaları İstanbul Hareket <i class="fa fa-chevron-right"></i></a>

Answer 1

我认为这就是你想要的：

.cruise-turlari .cruise-box .cruise-list-box ul li:hover:before, .cruise-turlari .cruise-box .cruise-list-box ul li:hover + li:before {
  height: 1px;
  background: transparent;
}

所以你也可以在悬停上使用相邻的兄弟选择器。

Answer 2

你添加一个特殊的类

.cruise-list-box ul li.special:after {
    height: 1px;
    opacity: 0;
}

然后，使用jQuery，在mouseover和mouseleave上添加事件

$('li').mouseover(function(){
  $(this).addClass('special');
});
$('li').mouseleave(function(){
 $(this).removeClass('special');
});
