javascript - 带有复选框的引导镜像

我有一个小问题，我正在尝试制作一个简单的图像，您可以单击它，然后将其选中或取消选中。

我在网上找到了一些引导代码，并在我的项目中进行了尝试。可悲的是，该代码似乎无法像在我的本地主机上那样工作。

HTML：

<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/font-awesome/4.6.3/css/font-awesome.min.css">
<div class="container">
  <h3>Bootstrap image checkbox(multiple)</h3>
  <div class="col-xs-4 col-sm-3 col-md-2 nopad text-center">
    <label class="image-checkbox">
      <img class="img-responsive" src="https://dummyimage.com/600x400/000/fff" />
      <input type="checkbox" name="image[]" value="" />
      <i class="fa fa-check hidden"></i>
    </label>
  </div>
  <div class="col-xs-4 col-sm-3 col-md-2 nopad text-center">
    <label class="image-checkbox">
      <img class="img-responsive" src="https://dummyimage.com/600x400/000/fff" />
      <input type="checkbox" name="image[]" value="" />
      <i class="fa fa-check hidden"></i>
    </label>
  </div>
  <div class="col-xs-4 col-sm-3 col-md-2 nopad text-center">
    <label class="image-checkbox">
      <img class="img-responsive" src="https://dummyimage.com/600x400/000/fff" />
      <input type="checkbox" name="image[]" value="" />
      <i class="fa fa-check hidden"></i>
    </label>
  </div>
  <div class="col-xs-4 col-sm-3 col-md-2 nopad text-center">
    <label class="image-checkbox">
      <img class="img-responsive" src="https://dummyimage.com/600x400/000/fff" />
      <input type="checkbox" name="image[]" value="" />
      <i class="fa fa-check hidden"></i>
    </label>
  </div>
  <div class="col-xs-4 col-sm-3 col-md-2 nopad text-center">
    <label class="image-checkbox">
      <img class="img-responsive" src="https://dummyimage.com/600x400/000/fff" />
      <input type="checkbox" name="image[]" value="" />
      <i class="fa fa-check hidden"></i>
    </label>
  </div>

</div>


CSS：

.nopad {
    padding-left: 0 !important;
    padding-right: 0 !important;
}
/*image gallery*/
.image-checkbox {
    cursor: pointer;
    box-sizing: border-box;
    -moz-box-sizing: border-box;
    -webkit-box-sizing: border-box;
    border: 4px solid transparent;
    margin-bottom: 0;
    outline: 0;
}
.image-checkbox input[type="checkbox"] {
    display: none;
}

.image-checkbox-checked {
    border-color: #4783B0;
}
.image-checkbox .fa {
  position: absolute;
  color: #4A79A3;
  background-color: #fff;
  padding: 10px;
  top: 0;
  right: 0;
}
.image-checkbox-checked .fa {
  display: block !important;
}


JavaScript：

$(".image-checkbox").each(function () {
  if ($(this).find('input[type="checkbox"]').first().attr("checked")) {
    $(this).addClass('image-checkbox-checked');
  }
  else {
    $(this).removeClass('image-checkbox-checked');
  }
});

// sync the state to the input
$(".image-checkbox").on("click", function (e) {
  $(this).toggleClass('image-checkbox-checked');
  var $checkbox = $(this).find('input[type="checkbox"]');
  $checkbox.prop("checked",!$checkbox.prop("checked"))

  e.preventDefault();
});


看起来如何：codepen

我的结果：results

如您所见，该复选框不起作用，位置已关闭。

我是一个初学者，对于给您带来的任何困惑，我深表歉意。

我做错什么了吗？

最佳答案

请尝试整个示例，从您的示例看来，您似乎尚未添加一些必要的CSS和jquery
