Twitter引导程序：在开放式手风琴标题中添加一个类

Question

I am a jquery/javascript newbie. What I want to do is add a class to the open accordion title, and remove it when i open another.

heres the code:

<div class="accordion" data-collapse-type="manual" id="parent">
  <div class="accordion-group">
    <div class="accordion-heading">             
      <a class="accordion-toggle category" data-toggle="collapse" data-parent="#parent" href="#category1">Category 1
      </a>
    </div><!--/accordion-heading-->
    <div id="category1" class="accordion-body collapse">
      <ul class="accordion-inner unstyled">
        <li id="" class="sidelink"><a href="">Open Link 1</a></li>
        <li id="" class="sidelink"><a href="">Open Link 2</a></li>
        <li id="" class="sidelink"><a href="">Open Link 3</a></li>
      </ul>
    </div><!--/category1-->
  </div><!--/accordion-group-->
  <div class="accordion-group">
    <div class="accordion-heading">
      <a class="accordion-toggle category" href="#Category2">Category 2</a>
    </div><!--/accordion-heading-->
  </div><!--/accordion-group-->
</div><!--/accordion-->

The scripts I have attached with the page are

<script src="js/jquery-1.7.1.min.js"></script>
<script src="js/bootstrap.min.js"></script>
<script src="js/jquery.tools.min.js"></script>

So what I was looking for was to add the .active class to a.accordion-toggle whenever the menu is open (accordion style), and then have it go away once another is selected. I've looked at the documentation to bootstrap here , but it doesnt seem to help me out a lot (since I don't know what to do with the

$('#myCollapsible').on('hidden', function () { // do something… })

or where to place it) I've also tried the .addClass() jquery adder, but I could only get the javascript version document.getElementById("accordion-heading").className += " newClass"; to work (if I gave the accordion group title an ID, but in this case there will be multiple accordion groups) when I put the script right after the div layer.

Answer 1

You can use the Collapse events for this.

$(function() {

    $('.accordion').on('show', function (e) {
         $(e.target).prev('.accordion-heading').find('.accordion-toggle').addClass('active');
    });

    $('.accordion').on('hide', function (e) {
        $(this).find('.accordion-toggle').not($(e.target)).removeClass('active');
    });

});​

Here's a JsFiddle http://jsfiddle.net/D2RLR/251/

Here's my solution to this problem. Based on some of the great answers above, but adapted to work with Bootstrap 3.1.x

$('#accordion')
  .on('show.bs.collapse', function(e) {
    $(e.target).prev('.panel-heading').addClass('active');
  })
  .on('hide.bs.collapse', function(e) {
    $(e.target).prev('.panel-heading').removeClass('active');
  });

Answer 3

我也想要添加一个“活动”类或类似但我在检查期间注意到，当非活动状态时，所有链接都有一个“折叠”类，当选择了选项卡/链接时，它会被删除，因此我只是简单地调整了选项卡而没有“倒塌”课。

Answer 4

I've tried Michael D. Irizarry's solution but that didn't work for me. So I came up with my own code:

$(function() {
    $('a.accordion-toggle').click(function(e) {
        e.preventDefault();
        if(!$(this).parent().hasClass('active')) {
            $('.accordion-heading').removeClass('active');
            $('.accordion-body').removeClass('active');
            $(this).parent().addClass('active').next().addClass('active');
        } else {
            $('.accordion-heading').removeClass('active');
            $('.accordion-body').removeClass('active');
        }
    });
});

If the accordion-heading already does not have a class of active, all accordion-headings & bodies lose the active class, and the one that has been clicked and it's corresponding body tag will get the class added.

If it already has the class active (so if it is already open and been clicked) then the active class is removed and nothing else happens.

Answer 5

simply check for the collapsed class added by the BS Code:

$('a.accordion-toggle').on('click', function () {
    if( $(this).hasClass('collapsed') !== true ){
        $(this).removeClass('active');
    }else{
        $(this).addClass('active');
    }
});

Answer 6

I think this is the simplest way so far.

$('a.accordion-toggle').on('click', function () {
  $('a.accordion-toggle').removeClass('active');
  $(this).addClass('active');
});

Answer 7

I think it would work if you put this on your javascript:

$('.accordion-toggle').on('shown', function () {
 $(this).addClass('active') });

$('.accordion-toggle').on('hidden', function () {
 $(this).removeClass('active') });

Answer 8

class active dont give the item becouse in less files this class changed you have to give it css instead class. this code is work best and you can add another css that you required

 $(function () {
            $('#accordion')
     .on('show.bs.collapse', function (e) {
         $(e.target).prev('.panel-heading').css({'background-color': 'red','color':'white'})
     })
     .on('hide.bs.collapse', function (e) {
         $(e.target).prev('.panel-heading').css({ 'background-color': '#b6ff00', 'color': 'black' })
     });
        });

Answer 9

This works for me using Bootstrap 3.3.6,

 $('#accordion')
   .on('show.bs.collapse', function (e) {
       $(e.target).parent('.panel').addClass('panel-primary');
   })
   .on('hide.bs.collapse', function (e) {
       $(e.target).parent('.panel').removeClass('panel-primary');
   });
        });

Answer 11

This works for me..

$('.panel-default').on('show.bs.collapse', function () {
     $('.panel-heading').addClass('active');
});

$('.panel-default').on('hide.bs.collapse', function () {
     $('.panel-heading').removeClass('active');
});
