JQuery UI 选项卡：非活动选项卡的文本仅在悬停时显示

Question

有人可以推荐一个仅在悬停时显示非活动选项卡文本的方法吗？我通常使用图标 + 文本作为标签，如下所示：

<a href="#myLeaves"><span class="ui-icon ui-icon-home"></span>Leaves</a></li>

以便非活动选项卡仅显示图标，而悬停时显示文本

Answer 1

您可以用 label 项目包裹您的文本，并最初通过 CSS 隐藏它。

然后，在你的菜单项上绑定一个hover函数，当鼠标指针进入时显示label，当鼠标指针离开时隐藏它：

$(function() {
  $("#menu a").hover(function() {
    $(this).find("label").show();
  }, function() {
    if (!$(this).hasClass("active")) {
      $(this).find("label").hide();
    }
  });
});

#menu a:not(.active) label {
  display: none;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://code.jquery.com/ui/1.12.0-rc.2/jquery-ui.min.js"></script>
<link href="https://code.jquery.com/ui/1.12.0-rc.2/themes/smoothness/jquery-ui.css" rel="stylesheet" />
<div id="menu">
  <a href="#home" class="active"><span class="ui-icon ui-icon-home"></span><label>home</label></a>
  </li>
  <a href="#flag"><span class="ui-icon ui-icon-flag"></span><label>flag</label></a>
  </li>
  <a href="#search"><span class="ui-icon ui-icon-search"></span><label>search</label></a>
  </li>
</div>

如果将文本包装在一个范围内，则可以使用单个 CSS 声明来处理。
例如，如果您用 class .tab-title 包装跨度，则：

.ui-tab:not(.ui-state-active):not(:hover) .tab-title {
  display: none; /*or opacity: 0; and animate away */
}

$(function() {
  $("#tabs").tabs();
});

.ui-tab:not(.ui-state-active):not(:hover) .tab-title {
  display: none;
  /*or opacity: 0; */
}

至于滑出视野，我会使用 overflow: hidden 的灵活宽度，如下所示：

* {
  box-sizing: border-box;
}
a {
  display: inline-block;
  border: 1px solid gray;
  position: relative;
  padding: 10px 10px 10px 28px;
  white-space: nowrap;
}
a > label {
  display: inline-block;
  overflow: hidden;
  width: 0;
  transition: width 0.5s;
}
a > span.ui-icon {
  position: absolute;
  margin-top: 0;
  left: 2px;
}

a:hover > label, a.active > label {
  width: 100%;
}

<link href="https://code.jquery.com/ui/1.12.0-rc.2/themes/smoothness/jquery-ui.css" rel="stylesheet"/>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://code.jquery.com/ui/1.12.0-rc.2/jquery-ui.min.js"></script>


<a class="active" href="#myLeaves"><span class="ui-icon ui-icon-home"></span><label>Leaves</label></a>
<a href="#flag"><span class="ui-icon ui-icon-flag"></span><label>long label</label></a>
<a href="#search"><span class="ui-icon ui-icon-search"></span><label>another long label</label></a>

我在这里使用了固定大小的标签，但您可以使用百分比值轻松地将其更改为灵活。
