当您单击引导按钮时，如何对其进行编码以打开模式？我需要JavaScript吗？我应该把它放在哪里

这是我的代码的副本，当前不起作用：

<!-- Trigger the modal with a button -->
                <button type="button" class="btn btn-info btn-lg" data-target="#myModal">Search Date/Time Select</button>
                <!-- Modal -->
                <div id="myModal" class="modal hide fade" role="dialog" bootstrap-toggle-modal="myModal" aria-hidden="true">
                    <div class="modal-dialog">
                        <!--Modal content-->
                        <div class="modal-content">
                            <div class="modal-header">
                                <h4 class="modal-title">Date/Time Select</h4>
                                <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
                            </div>
                            <div class="modal-body">
                                <p>Some text in the modal.</p>
                            </div>
                            <div class="modal-footer">
                                <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
                            </div>
                        </div>
                    </div>
                </div>

是的，您确实需要Javascript来实现此功能。具体来说，jQuery和Popper.js。BootStrap还有许多其他JavaScript插件

如果这不适用于您，请检查您的index.html是否按照

此代码按照

我不推荐它，但如果您希望使用早期版本：

我把上面的代码粘贴到了我的索引中，它消失了，但是保留页面加上弹出窗口是模态的。我不完全确定你对上面说的是什么？我提供的第二个代码片段提供了一个按钮，单击该按钮会打开一个模式，这是您最初要求的吗？我的建议是仔细阅读Bootstrap4文档。。。。这只是数据切换=模式。。是的，
