我怎样才能关闭旋转木马模态？

Question

我正在学习模态轮播，以便在用户点击图片缩略图时创建图片幻灯片，但我不知道如何创建关闭按钮以在幻灯片放映后关闭模式。

以下是代码：

<div class="modal fade" id="vnModal">
    <div class="modal-body">
        <div id="thanhhoa" class="carousel slide" data-ride="carousel">
            <!-- Indicators -->
            <ul class="carousel-indicators">
                <li data-target="#thanhhoa" data-slide-to="0" class="active"></li>
                <li data-target="#thanhhoa" data-slide-to="1"></li>
                <li data-target="#thanhhoa" data-slide-to="2"></li>
            </ul>
            <!-- The slideshow -->
            <div class="carousel-inner">
                <div class="carousel-item active">
                    <img src="http://go-ixe.com/img/thanhhoa/thanhhoa1.jpg" class="img-responsive image2" alt="ThanhHoa1" class="img-rounded">
                </div>
                <div class="carousel-item">
                    <img src="http://go-ixe.com/img/thanhhoa/thanhhoa2.jpg" class="img-responsive image2" alt="ThanhHoa2" class="img-rounded">
                </div>
                <div class="carousel-item">
                    <img src="http://go-ixe.com/img/thanhhoa/thanhhoa3.jpg" class="img-responsive image2" alt="ThanhHoa3" class="img-rounded">
                </div>
            </div>
            <!-- Left and right controls -->
            <a class="carousel-control-prev" href="#thanhhoa" data-slide="prev">
                <span class="carousel-control-prev-icon"></span>
            </a>
            <a class="carousel-control-next" href="#thanhhoa" data-slide="next">
                <span class="carousel-control-next-icon"></span>
            </a>
        </div>
    </div>  
 </div>
