引导程序崩溃关闭

Question

您好，我使用了此引导折叠代码，我希望一旦用户在面板外单击即可关闭此折叠。我尝试使用此脚本，但仍然无法满足我的期望。有人可以帮忙。 代码

<button class="btn btn-primary" type="button" data-toggle="collapse" data-target="#viewmore" aria-expanded="false" aria-controls="collapseExample">
    Open this 
  </button>
</p>
<div class="collapse" id="viewmore">
  <div class="card card-body">
 Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
  </div>
</div>

脚本

$(document).click(function(e) {
    if (!$(e.target).is('.panel-body')) {
        $('.collapse').collapse('hide');        
    }
});
