【问题描述】：

我无法让引导下拉菜单为自己工作。单击下拉菜单时不可见。我将其保留为我的下拉 HTML 代码

<div class="dropdown">                                                 
    <button class="btn btn-secondary dropdown-toggle" type="button" data-toggle="dropdown">
            Time period
    </button>
            <div class="dropdown-menu">
                 <a class="dropdown-item" v-bind:class="{ active: timeFilter==='7D' }" v-on:click="timeFilter='7D';updateCharts()">7 Days New</a>
                 <a class="dropdown-item" v-bind:class="{ active: timeFilter==='1M' }" v-on:click="timeFilter='1M';updateCharts()">1 month</a>
                 <a class="dropdown-item" v-bind:class="{ active: timeFilter==='3M' }" v-on:click="timeFilter='3M';updateCharts()">3 months</a>
            
            </div>
    </div>

我在末尾添加了以下内容

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/js/bootstrap.min.js"></script>

如果您想检查任何其他禁用执行的 CSS/JS 代码，此设置现在托管在 http://51.195.233.107/

感谢您的帮助。在过去的 5-6 个小时里，我一直坚持这一点。

感谢 Nagendra.. 但不知何故这不起作用。当有人点击按钮时，我终于写了一个代码让类“打开”，现在这似乎工作了。我仍然不明白为什么默认模块不起作用。
