Bootstrap崩溃。如何一次只展开一个 div

Question

我怎样才能一次显示一个？

$('.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;">

Bootstrap 手风琴。 jQuery vs HTML-属性

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

col-md-4 col-xs-4 等于 col-xs-4.
Bootstrap 包含 alignment classes。您可以使用 text-right class 而不是 style="text-align: right;".
请注意 .row class 具有属性 margin-right: -15px; margin-left: -15px;。你need to place.row内一个.container或.container-fluid.
style="height: 0px;" 是不必要的。 collapse class 设置 display 属性为 none.
id 必须是唯一的。

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>

将 .toggle class 添加到行中。这些块将切换相邻块的状态。
使用 .collapse class 使块可折叠。
该脚本执行两个操作：
- 隐藏所有展开的 div，除了下一个。
- 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>

按HTML-属性

N.B。此方法有效 in conjunction the panel component。可折叠块必须是具有 panel class.

的块的子块

将所有块包裹在 <div class="panel"></div> 中。
使用 .collapse class 使块可折叠。给这些块唯一的 ids.
将a set of attributes添加到每个切换块：

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>
