Question

我试图通过点击按钮在页面加载后向页面添加模态（在下面我在文档就绪而不是单击时做了）。通过克隆另一个模态然后将克隆附加到DOM来创建模态。模态节点出现在DOM中，但在给出.modal（）命令时，模态不会打开。我创建了一个简单的codepen来显示我的代码，并在下面显示它。

HTML：

<div id="LocalModalArea">
    <div class="modal fade" id="exampleModel" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
        <div class="modal-dialog" role="document">
            <div class="modal-content">
                <div class="modal-header">
                  <div id="myModalLabel" class="sideLineHeader">
                    <h2><span>Modal Header</span></h2>  
                  </div>
                </div>
                <div class="modal-body">
                </div>
                <div class="modal-footer">
                    <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
                </div>
            </div>
        </div>
    </div>
</div>

JS：

 $("Document").ready(function () {
   var newModal = $("#exampleModel").clone(true, true);
   newModal.attr("id", "NewModelId")
   $('#LocalModalArea').append(newModal)
   $("#NewModelId").modal("show")
 });

在您的codepen上，您尚未添加bootstrap所需的jQuery。

 $("Document").ready(function () {
   var newModal = $("#exampleModel").clone(false, true);
   newModal.attr("id", "NewModelId")
   $('#LocalModalArea').append(newModal);
   $("#NewModelId").addClass('super-red');
   $("#NewModelId").modal("show")
 });

.super-red{
	background-color: darkred;
}

                  </div>
                </div>
                <div class="modal-body">
                </div>
                <div class="modal-footer">
                    <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
                </div>
            </div>
        </div>

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>

</body>
</html>

注意，我添加了额外的css以突出显示克隆元素。
