下拉菜单不在bootstrap中工作

Question

我的网页有一个像

这样的导航栏

<ul class="nav navbar-nav navbar-right">
				<li class="dropdown">
					<a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false">
						<c:out value="${pageContext.request.remoteUser}"/>
						<span class="caret"></span>
					</a>
					<ul class="dropdown-menu" role="menu">
						<li>
							<a href="#" onclick="document.getElementById('logout-form').submit();">Logout</a>	
						</li>
					</ul>
				</li>
			</ul>

现在，当我点击下拉菜单而不是向我显示Logout选项时，没有任何反应，它只是在网址上附加了一个“＃”。例如，usr是http://localhost:8080/index，它变为http://localhost:8080/index#。我怎么能避免这个

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="sec" uri="http://www.springframework.org/security/tags" %>
<nav class="navbar navbar-default navbar-static-top">
		<div class="container-fluid">
			<!-- Brand and toggle get grouped for better mobile display -->
		<div class="navbar-header">
			<button type="button" class="navbar-toggle collapsed"
				data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
				<span class="sr-only">Toggle navigation</span> <span
					class="icon-bar"></span> <span class="icon-bar"></span> <span
					class="icon-bar"></span>
			</button>
			<a class="navbar-brand" href="#"><img src="/static/images/Snapdeal.png"></a>
		</div>
		<!-- Collect the nav links, forms, and other content for toggling 
		<input type="hidden" name="${_csrf.parameterName}" value="${_csrf.token}" /> -->
		<form id="logout-form" class="form-inline" action="/logout" style="display: none">
			<input type="submit" value="Logout" class="btn btn-link" />
			
		</form>
		<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
			<h3 class="navbar-text"><b>Crux Admin</b></h3>
			<ul class="nav navbar-nav">
				<c:choose>
					<c:when test="${param.currentPage eq 'dashboard'}">
						<c:set var="classValue" value="active" />
					</c:when>
					<c:otherwise>
						<c:set var="classValue" value="" />
					</c:otherwise>
				</c:choose>
				<li class="${classValue}"><a href="/index">Dashboard</a></li>
			</ul>
			
			
			<ul class="nav navbar-nav navbar-right">
				<li class="dropdown">
					<a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false">
						<c:out value="${pageContext.request.remoteUser}"/>
						<span class="caret"></span>
					</a>
					<ul class="dropdown-menu" role="menu">
						<li>
							<a href="#" onclick="document.getElementById('logout-form').submit();">Logout</a>	
						</li>
					</ul>
				</li>
			</ul>
		</div>
		<!-- /.navbar-collapse -->
	</div>
	<!-- /.container-fluid -->
</nav>

这是整个页面

在您的网页的一部分添加此行，它将起作用

<script  src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js" type="text/javascript"></script>
