有一个jquery .col-md-4，它将通过传递它将找到该元素的任何选择器来找到父元素。因此，在您的示例中，您必须通过该选择器传递类名.card或$("button").click(function () {
$(this).parents(".col-md-4").hide();
});，您可以执行任何操作
.col-md-4{border:1px red solid
}<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>

使用jQuery#parents方法并提供要隐藏的选择器。
如果您想要remove内容而不是hide，请使用
删除
$(this).parents('.col-md-4.col-xs-4').parent().empty();
隐藏
$(this).parents('.col-md-4.col-xs-4').hide();
<强>代码
$("button").click(function () {
$(this).parents('.col-md-4.col-xs-4').hide();
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class ="col-md-4 col-xs-4">
<div class="card" >
<img class="card-img-top" src="img/cheesecake-cream.jpg" alt="Chocolate cream">
<div class="card-body">
<h4 class="card-title">Chocolate cream</h4>
<p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
</div>
<div class= "card-body clearfix">
<div class="text-left text-success float-left">
<i class="fa fa-pencil" aria-hidden="true"></i><span id='clickableAwesomeFont'> Edit</span>
</div>
<div class="text-right text-danger float-right">

<button>Remove</button>

您可以使用解决方案
$("button").click(function () {
$(this).closest('div[class="col-md-4 col-xs-4"]').slideUp("slow", function(){
$(this).remove();
});
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>
<div class="col-md-4 col-xs-4">
<div class="card" >
<img class="card-img-top" src="img/cheesecake-cream.jpg" alt="Chocolate cream" />
<div class="card-body">
<h4 class="card-title">Chocolate cream</h4>
<p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
</div>
<div class= "card-body clearfix" >
<div class="text-left text-success float-left">
<i class="fa fa-pencil" aria-hidden="true"></i>
<span id='clickableAwesomeFont'> Edit</span>
</div>
<div class="text-right text-danger float-right">
<i class="fa fa-trash" aria-hidden="true"></i>
<span id='clickableAwesomeFont'> Delete</span>
<button>Remove</button>
</div>
</div>
</div>
</div>
我使用jQuery closest方法获取div而slideUp代替hide来获取动画。
slideUp完成后，它将删除div（这是一个回调）。
希望这会对你有所帮助。

closest只升级一级。您应该使用$("button").click(function () {
$(this).closest('div.col-md-4.col-xs-4').remove();
});
