引导3活动类添加/移除手风琴容器外的按钮

Bootstrap 3 active class add/remove on button outside of accordion container

本文关键字：手风琴 按钮 活动 添加 引导      更新时间：2023-09-26

我看了看周围，看到很多关于添加"active"类到触发手风琴的标题。但是我不知道如何将它添加到手风琴容器外的按钮。我读了关于引导3按钮切换(http://getbootstrap.com/javascript/#buttons)。这有点工作，但活动类不被删除时，点击另一个按钮。

这是我的HTML: 
<div class="btn-toolbar" role="toolbar">
              <div class="btn-group">
                  <a class="btn btn-default" data-toggle="collapse" data-parent="#accordion" href="#collapseOne">1</a>
                  <a class="btn btn-default" data-toggle="collapse" data-parent="#accordion" href="#collapseTwo">2</a>
                  <a class="btn btn-default" data-toggle="collapse" data-parent="#accordion" href="#collapseThree">3</a>
              </div>
              </div><!-- /.btn-toolbar -->
<div class="panel-group" id="accordion">
  <div class="panel panel-default">
    <div class="panel-heading">
      <h4 class="panel-title">
        <a data-toggle="collapse" data-parent="#accordion" href="#collapseOne">
          Collapsible Group Item #1
        </a>
      </h4>
    </div>
    <div id="collapseOne" class="panel-collapse collapse">
      <div class="panel-body">

    </div>
    <div id="collapseTwo" class="panel-collapse collapse">

也有一个JSfiddle设置在:http://jsfiddle.net/Bootstrap714/9Ljxbb2p/1/

我觉得这和"show .bs"有关。" Collapse "answers"hidden.bs.collapse"

Dan的第一个解决方案是一半正确的，因为当折叠折叠按钮时，按钮仍然是活动的(即单击按钮两次)，不应该是这种情况。我添加了一个if语句，使按钮在折叠时处于活动状态。

$('.btn').click(function(){
    $('.btn').removeClass('active');
    var collapseId = $(this).attr("href");
    if(!$(collapseId).hasClass("in")) { // the bootstrap class "in" when the collapse is expanded
        $(this).addClass('active');
    }
})

注意它是

if(!$(collapseId).hasClass("in"))

因为这是在折叠已经展开时执行的

可以使用show .bs。折叠，如文档中所示:

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

http://getbootstrap.com/javascript/崩溃

也许你也可以查看data-parent="#selector"部分设置另一个元素为活动

按钮实际上是关于别的东西，创建一个加载文本和禁用按钮点击。

比我原先预期的要复杂一些，但是您可以添加以下jQuery:

$('.btn').click(function(){
    active_change($(this));
});
$('.collapse-link').click(function(){
    var item = $('.collapse-' + $(this).attr("data-id"));
    active_change(item);
});
//the below activity is shared so it can be done in a single function, called from either  click above.  
function active_change(item){ 
    if($(item).hasClass('active')){
        $(item).removeClass('active');
    }else{   
        $('.btn').removeClass('active');
        $(item).addClass('active');
    }
}

并在html中添加适当的class和data-id属性。我所做的更改是，将面板手风琴链接更改为:

<a class="collapse-link" data-id="1" data-toggle="collapse" data-parent="#accordion" href="#collapseOne">

在数字链接中增加了collapse-1、collapse-2等类。
