jquery - Bootstrap 3 用雪佛龙图标折叠显示状态

Question

使用从 Bootstrap 3 Javascript示例页面中获取的核心示例 Collapse，我已经能够使用 V 形图标显示折叠状态。

我有这个工作使用：

$('#accordion .accordion-toggle').click(function (e) {
    var chevState = $(e.target).siblings("i.indicator").toggleClass('glyphicon-chevron-down glyphicon-chevron-up');
    $("i.indicator").not(chevState).removeClass("glyphicon-chevron-down").addClass("glyphicon-chevron-up");
});

这有效（未在所有浏览器中完全测试），但我想知道是否有更优雅的解决方案？

理想情况下，我想使用核心功能，但我不确定如何使用它来获得相同的结果。

$('#accordion').on('hidden.bs.collapse', function () {
    //do something...
})

这是jsfiddle的工作版本。

对于以下 HTML（来自Bootstrap 3 示例）：

.panel-heading .accordion-toggle:after {
    /* symbol for "opening" panels */
    font-family: 'Glyphicons Halflings';  /* essential for enabling glyphicon */
    content: "\e114";    /* adjust as needed, taken from bootstrap.css */
    float: right;        /* adjust as needed */
    color: grey;         /* adjust as needed */
}
.panel-heading .accordion-toggle.collapsed:after {
    /* symbol for "collapsed" panels */
    content: "\e080";    /* adjust as needed, taken from bootstrap.css */

改进 Bludream 的答案：

你绝对可以使用 FontAwesome！

确保包括“折叠”和“面板标题”类。在您单击面板之前不包含“折叠”类，因此您希望包含“折叠”类以显示正确的 chevron（即，折叠时显示 chevron-right，打开时显示 chevron-down）。

HTML

<div class="panel panel-default">
    <div class="panel-heading collapsed" data-toggle="collapse" data-target="#collapseOrderItems1">Products 1 <i class="chevron fa fa-fw" ></i></div>
    <div class="collapse" id="collapseOrderItems1">
        <p>Lorem ipsum...</p>
    </div>
</div>

CSS

.panel-heading .chevron:after {
    content: "\f078";   
}
.panel-heading.collapsed .chevron:after {
    content: "\f054";   
}

此外，最好创建一个新类而不是使用现有类。

我知道这是旧的，但因为现在是 2018 年，我想我会通过简化代码并通过使雪佛龙基于折叠与否旋转来增强用户体验来回复它。不过，我正在使用 FontAwesome。这是CSS：

a[data-toggle="collapse"] .rotate {
   -webkit-transition: all 0.2s ease-out;
   -moz-transition: all 0.2s ease-out;
   -ms-transition: all 0.2s ease-out;
   -o-transition: all 0.2s ease-out;
   transition: all 0.2s ease-out;
   -moz-transform: rotate(90deg);
   -ms-transform: rotate(90deg);
   -webkit-transform: rotate(90deg);
   transform: rotate(90deg);
}
a[data-toggle="collapse"].collapsed .rotate {
   -moz-transform: rotate(0deg);
   -ms-transform: rotate(0deg);
   -webkit-transform: rotate(0deg);
   transform: rotate(0deg);
}

这是面板部分的 HTML：

  <div class="panel panel-default">
    <div class="panel-heading">
      <h4 class="panel-title">
        <a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion" href="#collapseOne">

我使用 bootstraps pull-right 将人字形拉到面板标题的右侧，面板标题应该是全宽和响应式的。CSS 完成所有动画工作，并根据面板是否折叠来旋转 V 形。简单的。

这里有几个纯 css 帮助类，可以让您在 html 中处理任何类型的切换内容。

它适用于您需要切换的任何元素。无论您的布局是什么，您只需将其放在切换元素中带有 .if-collapsed 和 .if-not-collapsed 类的几个元素中。

唯一需要注意的是，您必须确保设置了所需的切换初始状态。如果它最初是关闭的，则在切换开关上放置一个折叠的类。

它还需要:not选择器，它在 IE8 上不起作用。

HTML 示例：

<a class="btn btn-primary collapsed" data-toggle="collapse" href="#collapseExample">
  <!--You can put any valid html inside these!-->
  <span class="if-collapsed">Open</span>
  <span class="if-not-collapsed">Close</span>
</a>
<div class="collapse" id="collapseExample">
  <div class="well">
    ...
  </div>
</div>

少版本：

[data-toggle="collapse"] {
    &.collapsed .if-not-collapsed {
         display: none;
    }
    &:not(.collapsed) .if-collapsed {
         display: none;
    }
}

CSS 版本：

[data-toggle="collapse"].collapsed .if-not-collapsed {
  display: none;
}
[data-toggle="collapse"]:not(.collapsed) .if-collapsed {
  display: none;
}

单线。

i.fa.fa-chevron-right.collapse.in { transform: rotate(180deg); }

在此示例中，它用于对可折叠表格行进行分组。您唯一需要做的就是将目标类名称（my-collapse-name）添加到您的图标中：

<tr data-toggle="collapse" data-target=".my-collapse-name">
    <th><i class="fa fa-chevron-right my-collapse-name"></span></th>
    <th>Master Row - Title</th>
</tr>
<tr class="collapse my-collapse-name">
    <td></td>
    <td>Detail Row - Content</td>
</tr>

您可以通过使用<span class='caret my-collapse-name'></span>和span.caret.collapse.in { transform: rotate(90deg); }

Angular 似乎会导致这里基于 JavaScript 的方法出现问题（至少我尝试过的那些）。我在这里找到了这个解决方案：http: //www.codeproject.com/Articles/987311/Collapsible-Responsive-Master-Child-Grid-Using-Ang。它的要点是在切换按钮上使用，并使用上下文data-ng-click创建更改控制器中按钮的方法。$scope

我想我可以提供更多细节......我的按钮设置为它们折叠的 div 的初始状态的字形图标（ glyphicon-chevron-right == collapsed div ）。

page.html：

<div class="title-1">
    <button data-toggle="collapse" data-target="#panel-{{ p_idx }}" class="dropdown-toggle title-btn glyphicon glyphicon-chevron-right" data-ng-click="collapse($event)"></button>
</div>
<div id="panel-{{ p_idx }}" class="collapse sect">
    ...
</div>

控制器.js：

.controller('PageController', function($scope, $rootScope) {
    $scope.collapse = function (event) {
        $(event.target).toggleClass("glyphicon-chevron-down glyphicon-chevron-right");
    };
)

如果您尝试仅将其与面板一起使用（而不是手风琴），请尝试以下代码：
