Bootstrap手风琴-活动按钮

Question

I have a Bootstrap accordion with an horizontal menu. I'm trying to change the background of the active button.

I have played a lot in JDFIDDLE without any result.

In order not to got crazy and avoid a larger mess, I did stop to claim for help.

Please check the JSFIDDLE

JS:

$("#nav2 a").on("click", function(){
   $("#nav2").find(".active").removeClass("active");
   $(this).parent().addClass("active");
});

CSS:

#nav2  a:active,
#nav2  a:hover,
#nav2  a:focus {
   color: #fff; 
   background-color: #000 !important;
   font-weight: bold;
}

Answer 1

It seems to me that tabs are more suited for what you're trying to do than accordion.

HTML:

<div>

  <!-- Nav tabs -->
  <ul class="nav nav-tabs" role="tablist">
    <li role="presentation" class="active"><a href="#home" aria-controls="home" role="tab" data-toggle="tab">Home</a></li>
    <li role="presentation"><a href="#profile" aria-controls="profile" role="tab" data-toggle="tab">Profile</a></li>
    <li role="presentation"><a href="#messages" aria-controls="messages" role="tab" data-toggle="tab">Messages</a></li>
    <li role="presentation"><a href="#settings" aria-controls="settings" role="tab" data-toggle="tab">Settings</a></li>
  </ul>

  <!-- Tab panes -->
  <div class="tab-content">
    <div role="tabpanel" class="tab-pane active" id="home">Raw denim you probably haven't heard of them jean shorts Austin.</div>
    <div role="tabpanel" class="tab-pane" id="profile">Food truck fixie locavore, accusamus mcsweeney's marfa nulla single-origin coffee squid.</div>
    <div role="tabpanel" class="tab-pane" id="messages">Etsy mixtape wayfarers, ethical wes anderson tofu before they sold out mcsweeney's organic lomo retro fanny pack lo-fi farm-to-table readymade.</div>
    <div role="tabpanel" class="tab-pane" id="settings">Trust fund seitan letterpress, keytar raw denim keffiyeh etsy art party before they sold out master cleanse gluten-free squid scenester freegan cosby sweater.</div>
  </div>

</div>

Answer 2

Try this:

JQUERY

$("#headingOne a").on("click", function(){
   $(this).addClass("active");
   $("#headingOne").find('.active').not(this).removeClass("active");
});

I added this CSS: .active { color:#ccc !important;} so that you can see which menu item is active.
