Bootstrap nested accordion font-awesome icons
提问by Janshair Khan
I've a 3 level nested bootstrap accordion which is working fine, but I want a change in the panel-heading divwhere I can use a font-awesome icon fa fa-chevron-downwhen the accordion is opened (Without affecting the nested accordions) and fa fa-chevron-rightwhen accordion is collapsed. I'm using this code to changing the icon:
我有一个 3 级嵌套的自举手风琴，它工作正常，但我想在面板标题 div中进行更改，fa fa-chevron-down当手风琴打开时（不影响嵌套的手风琴）和fa fa-chevron-right手风琴打开时，我可以使用字体很棒的图标崩溃了。我正在使用此代码更改图标：
$('div.panel-collapse.collapse').on('shown.bs.collapse', function() {
$(this).parent().find(".fa-chevron-right").removeClass("fa-chevron-right").addClass("fa-chevron-down");
$(this).parent().find('.panel-heading').css('background', '#0271BC');
}).on('hidden.bs.collapse', function() {
$(this).parent().find(".fa-chevron-down").removeClass("fa-chevron-down").addClass("fa-chevron-right");
$(this).parent().find('.panel-heading').css('background', '#02A4EF');

但是这段代码也改变了尚未打开的嵌套手风琴的图标。有没有更好的方法来解决这个问题将不胜感激。
回答by Gleb Kemarsky
I prefer to use examples form the Bootstrap documentation and toggle icons by CSS.
我更喜欢使用 Bootstrap 文档中的示例并通过 CSS 切换图标。
And I've added Font Awesome icons as a content of the :afterpseudo-element.
而且我已经添加字体真棒图标为内容的 :after伪元素。

Found an existing jsFiddle: http://jsfiddle.net/zessx/r6eaw/12/and with a little copy-paste, one with a nested accordion: http://jsfiddle.net/R6EAW/3979/
找到了一个现有的 jsFiddle：http: //jsfiddle.net/zessx/r6eaw/12/和一个小的复制粘贴，一个嵌套的手风琴：http: //jsfiddle.net/R6EAW/3979/
One of the issues with your code is that you are nesting div's in anchor (<a/>) tags. That is not allowed.
您的代码的问题之一是您将 div 嵌套在锚 ( <a/>) 标签中。这是不允许的。

Here's a simple example, with this, initially show the icons correctly using Jquery and Bootstrap.
