Question

我正在尝试实现twitter bootstrap可折叠导航栏。在桌面导航栏上可见，但在移动屏幕上它不可见。这是View Part

<div class="masthead clearfix">
                    <div class="inner">
                        <h3 class="masthead-brand"><img src="/x/img/X.png" style="width:80px; position:relative; top:-20px;"></img></h3>
                        <div class="container">
                            <div class="navbar-header">
                                <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar">
                                    <span class="icon-bar"></span>
                                    <span class="icon-bar"></span>
                                    <span class="icon-bar"></span>
                                </button>

                            </div>
                            <div id="navbar" class="navbar-collapse collapse">

                                <ul class="nav navbar-nav navbar-right" style="margin-top:15px;background-color:rgba(255,255,255,.4)">

                                    <li class="active"><a class="call_us btn btn-default no-rounded btn-hollow" th:text="${'+91 444}" style="cursor:default; pointer-events:none;"> Call Us 555</a></li>

                                    <li ><a th:href="@{/X}" href="#">X</a></li>
                                    <li><a th:href="@{/Y}" href="#">Y</a></li>
                                    <li><a th:href="@{/Z}" href="#">Z</a></li>
                                    <li><a th:href="@{/T}" href="#">C</a></li>
                                    <li class="active"><a th:href="#" href="#">Blog</a></li>
                                    <!--li><a href="#">Help</a></li-->
                                </ul>
                            </div><!--/.nav-collapse -->
                        </div>
                    </div>
                </div>

有人可以帮我解决这个问题。我在我的路径中包含了collapse.js。

您错过了navbar类，它是Bootstrap中默认导航的第一行。请参阅Docs。
