我正在尝试将bootstrap Accordion添加到我的项目中，但它无法正常工作....我在下面添加了JavaScript代码的问题是什么。

我还在我的项目中包含以下文件。 提前致谢。 问候。

为了改变我想建议使用的手风琴图标：

$(document).ready(function () {
  $('.collapse').on('show.bs.collapse hide.bs.collapse', function () {
      $(this).closest('.panel').find('.panel-heading .glyphicon').toggleClass('glyphicon-collapse-down glyphicon-collapse-up')
  });
});

您可以查找上一个元素，并找到类.glyphicon的范围。 然后只需添加或删除上下类。

这是一个例子。

$('.collapse')
  .on('show.bs.collapse', function () {
  $(this).prev().find('.glyphicon')
    .removeClass('glyphicon-collapse-down')
    .addClass('glyphicon-collapse-up')
})
  .on('hide.bs.collapse', function () {
  $(this).prev().find('.glyphicon')
    .removeClass('glyphicon-collapse-up')
    .addClass('glyphicon-collapse-down')
});

请参阅此链接。 http://jsfiddle.net/panchroma/3gYa3/

仅使用CSS的Bootstrap手风琴

.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 */
}
