Question

所以我使用bootstrap并且我希望实现折叠面板加上和减去图标。

我目前使用stackoverflow上的代码完成它，我无法记住链接，因此稍后会编辑。它使用下面的代码，但是我必须为每组折叠面板复制它，因为它们具有唯一的ID。有没有办法，所以它只需要一次，并将在同一页面上多个工作？

jQuery(function ($) {
  var $active = $('#accordionthree .panel-collapse.in').prev().addClass('active');
  $active.find('.symbol').append('<span class="glyphicon glyphicon-minus pull-left"></span>');
  $('#accordionthree .panel-heading').not($active).find('.symbol').prepend('<span class="glyphicon glyphicon-plus pull-left"></span>');
  $('#accordionthree').on('show.bs.collapse', function (e)
  {
    $('#accordionthree .panel-heading.active').removeClass('active').find('.glyphicon').toggleClass('glyphicon-plus glyphicon-minus');
    $(e.target).prev().addClass('active').find('.glyphicon').toggleClass('glyphicon-plus glyphicon-minus');
  });
  $('#accordionthree').on('hide.bs.collapse', function (e)
  {
    $(e.target).prev().removeClass('active').find('.glyphicon').removeClass('glyphicon-minus').addClass('glyphicon-plus');
  });
});

CSS解决方案：

.panel-heading a:after {
    font-family:'Glyphicons Halflings';
    content:"\2212";
    float: right;
    color: grey;
}
.panel-heading a.collapsed:after {
    content:"\2b";
}

基于 Collapse accordion example 中的展开示例并使用font-awesome。

希望这有帮助。

.panel-heading a:after {
  font-family:'Glyphicons Halflings';
  content:"\2212";
  float: right;
  color: grey;
}
.panel-heading a.collapsed:after {
  content:"\2b";
}
