Bootstrap折叠.如何一次只扩展一个div

Question

我怎样才能一次展示一个？

演示:http://jsfiddle.net/tvvq59wv/

$('.collapser').click(function() {
  $(this).next().collapse('toggle');
});

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" integrity="sha384-1q8mTJOASx8j1Au+a5WDVnPi2lkFfwwEAa8hDDdjZlpLegxhjVME1fgjWPGmkzs7" crossorigin="anonymous">

<div id="myGroup">
  <div aria-controls="collapseExample" aria-expanded="false" data-toggle="collapse" class=" row collapsed collapser" style="background: #ddd;">
    <div class="col-md-4 col-xs-4">asfa asf asfasf afsf afsasf asf asf asf adf</div>
    <div class="col-md-4 col-xs-4">test</div>
    <div class="col-md-4 col-xs-4" style="text-align: right;">asf afsas afsasf asf</div>
  </div>

  <div id="collapseExample" class="collapse" style="height: 0px;">
    <div class="well">asf t1</div>
  </div>

  <div aria-controls="collapseExample" aria-expanded="false" data-toggle="collapse" class=" row collapsed collapser" style="background: #ddd;">
    <div class="col-md-4 col-xs-4">asfa afsasf</div>

    <div class="col-md-4 col-xs-4" style="text-align: right;">asf afsas afsasf asf</div>

Bootstrap手风琴.jQuery vs HTML-attributes

有两种方法可以解决您的问题.您可以使用Javascript或分配HTML属性.但首先我们简化了代码.

起点

1. col-md-4 col-xs-4等于col-xs-4.
2. Bootstrap包含对齐类.您可以使用text-right该类而不是style="text-align: right;".
3. 请注意,.row该类具有属性margin-right: -15px; margin-left: -15px;.你需要放在 .row一个.container或.container-fluid.
4. style="height: 0px;"没必要.该collapse级设置display财产none.
5. id 必须是独一无二的

让我们从这段代码开始:

https://jsfiddle.net/glebkema/a5q9mgho/

@import url('https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css');

.text {
  margin-bottom: 20px;
  padding: 15px;
}

.mauve { background: #c9f }
.mint  { background: #9fc }
.peach { background: #fc9 }

.text.mauve { background: #edf }
.text.mint  { background: #dfe }
.text.peach { background: #fed }

<div id="myGroup" class="container">

  <div class="row mint">
    <div class="col-xs-4">left</div>
    <div class="col-xs-4 text-center">center</div>
    <div class="col-xs-4 text-right">right</div>
  </div>
  <div class="row">
    <div class="text mint">text</div>
  </div>

  <div class="row mauve">
    <div class="col-xs-4">left</div>
    <div class="col-xs-4 text-center">center</div>
    <div class="col-xs-4 text-right">right</div>
  </div>
  <div class="row">
    <div class="text mauve">text</div>
  </div>

  <div class="row peach">
    <div class="col-xs-4">left</div>
    <div class="col-xs-4 text-center">center</div>
    <div class="col-xs-4 text-right">right</div>
  </div>
  <div class="row">
    <div class="text peach">text</div>
  </div>

</div>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>

通过jQuery

1. 将.toggle类添加到行.这些块将切换相邻块的状态.
2. 使用.collapse该类可以使块可折叠.
3. 该脚本执行两个操作:
   • 隐藏除下一个之外的所有扩展div.
   • 切换下一个div.

http://jsfiddle.net/glebkema/73gtkvjt/

$('.toggle').click(function() {
  if ( !$(this).next().hasClass('in') ) {
    $(this).parent().children('.collapse.in').collapse('hide');
  }
  $(this).next().collapse('toggle');
});

@import url('https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css');

.text {
  margin-bottom: 20px;
  padding: 15px;
}

.mauve { background: #c9f }
.mint  { background: #9fc }
.peach { background: #fc9 }

.text.mauve { background: #edf }
.text.mint  { background: #dfe }
.text.peach { background: #fed }

<div id="myGroup" class="container">

  <div class="row mint toggle">
    <div class="col-xs-4">left</div>
    <div class="col-xs-4 text-center">center</div>
    <div class="col-xs-4 text-right">right</div>
  </div>
  <div class="row collapse in">
    <div class="text mint">text</div>
  </div>

  <div class="row mauve toggle">
    <div class="col-xs-4">left</div>
    <div class="col-xs-4 text-center">center</div>
    <div class="col-xs-4 text-right">right</div>
  </div>
  <div class="row collapse">
    <div class="text mauve">text</div>
  </div>

  <div class="row peach toggle">
    <div class="col-xs-4">left</div>
    <div class="col-xs-4 text-center">center</div>
    <div class="col-xs-4 text-right">right</div>
  </div>
  <div class="row collapse">
    <div class="text peach">text</div>
  </div>

</div>

通过HTML属性

注意此方法与面板组件结合使用.可折叠块必须是块的子节点,它具有panel类.

1. 包裹所有块<div class="panel"></div>.
2. 使用.collapse该类可以使块可折叠.给这些块独特的ids.
3. 为每个切换块添加一组属性:

role="button" data-toggle="collapse" data-parent="#myGroup" href="#collapseOne" aria-expanded="false" aria-controls="collapseOne"

https://jsfiddle.net/glebkema/L02ao1n9/

@import url('https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css');

.panel {
  border: 0;
  margin-bottom: 0;
}

.text {
  margin-bottom: 20px;
  padding: 15px;
}

.mauve { background: #c9f }
.mint  { background: #9fc }
.peach { background: #fc9 }

.text.mauve { background: #edf }
.text.mint  { background: #dfe }
.text.peach { background: #fed }

<div id="myGroup" class="container">
  <div class="panel">

    <div class="row mint" role="button" data-toggle="collapse" data-parent="#myGroup" href="#collapseOne" aria-expanded="false" aria-controls="collapseOne">
      <div class="col-xs-4">left</div>
      <div class="col-xs-4 text-center">center</div>
      <div class="col-xs-4 text-right">right</div>
    </div>
    <div id="collapseOne" class="row collapse in">
      <div class="text mint">text</div>
    </div>

    <div class="row mauve" role="button" data-toggle="collapse" data-parent="#myGroup" href="#collapseTwo" aria-expanded="false" aria-controls="collapseTwo">
      <div class="col-xs-4">left</div>
      <div class="col-xs-4 text-center">center</div>
      <div class="col-xs-4 text-right">right</div>
    </div>
    <div id="collapseTwo" class="row collapse">
     <div class="text mauve">text</div>
    </div>
    
    <div class="row peach" role="button" data-toggle="collapse" data-parent="#myGroup" href="#collapseThree" aria-expanded="false" aria-controls="collapseThree">
      <div class="col-xs-4">left</div>
      <div class="col-xs-4 text-center">center</div>
      <div class="col-xs-4 text-right">right</div>
    </div>
    <div id="collapseThree" class="row collapse">
      <div class="text peach">text</div>
