javascript - 使用 jQuery 触发 css 悬停

Question

是否可以使用 jQuery(或纯 CSS)将 CSS 悬停操作链接到另一个链接？

我有一个组合的悬停和工具提示动画，意思是覆盖在 map 上。我想要实现的是在将鼠标悬停在列表中的城市名称上时触发悬停。

a {
  text-decoration: none;
}
a:hover {
  color:  #d82631;
}

.location {
  position: absolute;
}

.kart_dot {
  position: relative;
  width: 20px;
  height: 20px;
  margin-top: -10px;
  margin-left: -10px;
  cursor: pointer;
}

.kart_dot::before {
  display: block;
  content: "";
  position: absolute;
  top: 50%;
  left: 50%;
  width: 12px;
  height: 12px;
  background: #d82631 none repeat scroll 0% 0%;
  border-radius: 50%;
  margin-top: -6px;
  margin-left: -6px;
}

.kart_dot:hover::before,
.kart_dot:focus::before,
.kart_dot:active::before {
  background-color: #000;
  -webkit-transition: all 0.20s ease-in-out !important;
  -moz-transition: all 0.20s ease-in-out !important;
  -ms-transition: all 0.20s ease-in-out !important;
  -o-transition: all 0.20s ease-in-out !important;
  width: 18px;
  height: 18px;
  margin-top: -9px;
  margin-left: -9px;
}

[data-tooltip]:before,
[data-tooltip]:after,
.tooltip:before,
.tooltip:after {
  position: absolute;
  visibility: hidden;
  -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";
  filter: progid: DXImageTransform.Microsoft.Alpha(Opacity=0);
  opacity: 0;
  -webkit-transition: opacity 0.2s ease-in-out, visibility 0.2s ease-in-out, -webkit-transform 0.2s cubic-bezier(0.71, 1.7, 0.77, 1.24);
  -moz-transition: opacity 0.2s ease-in-out, visibility 0.2s ease-in-out, -moz-transform 0.2s cubic-bezier(0.71, 1.7, 0.77, 1.24);
  transition: opacity 0.2s ease-in-out, visibility 0.2s ease-in-out, transform 0.2s cubic-bezier(0.71, 1.7, 0.77, 1.24);
  -webkit-transform: translate3d(0, 0, 0);
  -moz-transform: translate3d(0, 0, 0);
  transform: translate3d(0, 0, 0);
  pointer-events: none;
}

[data-tooltip]:hover:before,
[data-tooltip]:hover:after,
[data-tooltip]:focus:before,
[data-tooltip]:focus:after,
.tooltip:hover:before,
.tooltip:hover:after,
.tooltip:focus:before,
.tooltip:focus:after {
  visibility: visible;
  -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=100)";
  filter: progid: DXImageTransform.Microsoft.Alpha(Opacity=100);
  opacity: 1;
}

.tooltip:after,
[data-tooltip]:after {
  z-index: 1000;
  padding: 15px;
  width: 160px;
  color: #000;
  content: attr(data-tooltip);
  font-size: 14px;
  line-height: 0.9;
}

.tooltip-hoyre:before,
.tooltip-hoyre:after {
  bottom: 50%;
  left: 100%;
}

.tooltip-hoyre:before {
  margin-bottom: 0;
  margin-left: -8px;
  border-top-color: transparent;
  border-right-color: #000;
  border-right-color: hsla(0, 0%, 20%, 0.9);
}

.tooltip-hoyre:hover:before,
.tooltip-hoyre:hover:after,
.tooltip-hoyre:focus:before,
.tooltip-hoyre:focus:after {
  -webkit-transform: translateX(12px);
  -moz-transform: translateX(12px);
  transform: translateX(12px);
}

.tooltip-hoyre:after {
  margin-left: 0;
  margin-bottom: -16px;
  margin-left: -18px;
}

<div><a href="#new_york">New York</a></div>
<div><a href="#washington">Washington</a></div>

<div class="location" style="top: 20%; left: 20%;">
  <a href="#new_york" class="tooltip-hoyre" data-tooltip="New York">
    <div class="kart_dot"></div>
  </a>
</div>

<div class="location" style="top: 38%; left: 20%;">
  <a href="#washington" class="tooltip-hoyre" data-tooltip="Washington">
    <div class="kart_dot"></div>
  </a>
</div>

我还把它作为 fiddle 包括在内:https://jsfiddle.net/7Lsvdqpx/3/

我已经尝试了几种建议的方法，但都没有成功，例如:Trigger hover with jQuery?

Answer 1

您可以通过使用相邻的选择器 (~) 使用纯 CSS 而无需 jQuery 来完成此操作。我已经在下面的代码片段中实现了它，并且不得不添加一些 HTML 类。以下是其工作原理的示例:

.list-ny:hover ~ .location .dot-ny:before,
.list-ny:hover ~ .location .dot-ny:after,
.list-wa:hover ~ .location .dot-wa:before,
.list-wa:hover ~ .location .dot-wa:after

上面的代码片段说...如果您将鼠标悬停在 .list-ny 菜单项上，然后选择一个相邻的 .location 元素，该元素有一个 .dot -ny:before 并应用相关样式。

这是为所有相关属性实现悬停的完整示例:

a {
  text-decoration: none;
}

a:hover {
  color: #d82631;
}

.location {
  position: absolute;
}

.kart_dot {
  position: relative;
  width: 20px;
  height: 20px;
  margin-top: -10px;
  margin-left: -10px;
  cursor: pointer;
}

.kart_dot::before {
  display: block;
  content: "";
  position: absolute;
  top: 50%;
  left: 50%;
  width: 12px;
  height: 12px;
  background: #d82631 none repeat scroll 0% 0%;
  border-radius: 50%;
  margin-top: -6px;
  margin-left: -6px;
}

.kart_dot:hover::before,
.kart_dot:focus::before,
.kart_dot:active::before,
.list-ny:hover ~ .location .dot-ny .kart_dot:before,
.list-wa:hover ~ .location .dot-wa .kart_dot:before {
  background-color: #000;
  -webkit-transition: all 0.20s ease-in-out !important;
  -moz-transition: all 0.20s ease-in-out !important;
  -ms-transition: all 0.20s ease-in-out !important;
  -o-transition: all 0.20s ease-in-out !important;
  width: 18px;
  height: 18px;
  margin-top: -9px;
  margin-left: -9px;
}

[data-tooltip]:before,
[data-tooltip]:after,
.tooltip:before,
.tooltip:after {
  position: absolute;
  visibility: hidden;
  -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";
  filter: progid: DXImageTransform.Microsoft.Alpha(Opacity=0);
  opacity: 0;
  -webkit-transition: opacity 0.2s ease-in-out, visibility 0.2s ease-in-out, -webkit-transform 0.2s cubic-bezier(0.71, 1.7, 0.77, 1.24);
  -moz-transition: opacity 0.2s ease-in-out, visibility 0.2s ease-in-out, -moz-transform 0.2s cubic-bezier(0.71, 1.7, 0.77, 1.24);
  transition: opacity 0.2s ease-in-out, visibility 0.2s ease-in-out, transform 0.2s cubic-bezier(0.71, 1.7, 0.77, 1.24);
