javascript - 如何根据另一个div的高度更改一个div的最小高度

Question

我们有两个 div，其中一个 div 只包含内容，另一个有 bootstraps collapse with content 。所以这里发生的是当我们点击可折叠元素时 它会打开并且它的父级的高度会自动增加。我们有很多可折叠的 div。

Now how we can set the div 1 height is same as with div 2 height ?. If div 2 height increase then div 1 height also need to increase.

<div class="container">
  <h2>Accordion Example</h2>
  <p><strong>Note:</strong> The <strong>data-parent</strong> attribute makes sure that all collapsible elements under the specified parent will be closed when one of the collapsible item is shown.</p>

  <div class="col-sm-6 div1">

Answer 1

$(".div1").css({
  'height': ($(".div2").height() + 'px')
});

$('#accordion').on('hidden.bs.collapse', function() {
  // do something…
  $(".div1").css({
    'height': ($(".div2").height() + 'px')
  });
})

使用Bootstrap方法的更好方法
