Css 引导程序3中的导航栏折叠不工作

我有一些下面的HTML代码与Twitter引导

<nav class="navbar navbar-inverse navbar-fixed-top">
    <div class="container">
        <div class="col-sm-4">
            <a href="#"><img src="img/logo.png" class="img-responsive"/></a>
        </div>

        <div class="col-sm-8 col-sm-12">
            <div class="col-sm-3 pull-right">
                <ul class="social pull-right ul-social-link">
                                <li style="background: none"> <a href="#"> <i class=" fa fa-facebook">   </i> </a> </li>
                                <li style="background: none"> <a href="#"> <i class="fa fa-twitter">   </i> </a> </li>
                                <li style="background: none"> <a href="#"> <i class="fa fa-google-plus">   </i> </a> </li>
                            </ul>
            </div>
            <div class="col-sm-8 pull-right">
                <div class="col-md-5 pull-right text-right">
                    <p class="contact"><a href="#"><span class="glyphicon glyphicon-phone-alt" aria-hidden="true"></span> +912345678910</a></p>
                </div>
                <div class="col-sm-5 pull-right">
                    <p class="contact"><a href="#"><span class="glyphicon glyphicon-envelope" aria-hidden="true"></span> mail@indtechhc.com</a></p>
                </div>
            </div>
            <div class="clearfix"></div>
            <div class="col-sm-12">
                <button class="navbar-toggle" data-toggle="collapse" data-target=".navHeaderCollapse">
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>
                </button>
                <div class="collapse navbar-collapse navHeaderCollapse">
                    <ul class="nav navbar-nav navbar-right">
                        <li class="active"><a href="#">Home</a><li>
                        <li><a href="#">We are</a><li>
                        <li><a href="#">Products</a><li>
                        <li><a href="#">About us</a><li>
                        <li><a href="#">Contact us</a><li>
                    </ul>
                </div>
            </div>
        </div>
    </div>
</nav>

但当我触发折叠按钮时，它不工作！请给出建议。

确保您包含jquery.js，并且它在引导之前。min.js

您希望结果如何？它在这里工作：您的代码（js或CSS）中是否有其他东西会弄乱它？是的，我是@neilsimp1。它也适用于此缺少的元素是什么？您是否记得在

部分中包含bootstrap.js？
