jQuery：加载的HTML是不可见的

Question

我目前尝试使用jQuery和此代码将HTML代码加载到div中：

<script language="javascript">
   $(function(){
      $(".loadmain").click(function(){
         $("#main-content").load("startjourney2.html");
      });
   });
</script>

我的按钮在这里：

<a class="loadmain">Play</a>

我的div下面

<div id="main-content" class="abs dark-template">

最后但并非最不重要的是startjourney2.html中的代码

<div class="page-wrapper">

    <!--Page sidebar-->
    <div class="page-side">
        <div class="inner-wrapper vcenter-wrapper">
            <div class="side-content vcenter">
                <div class="title">
                    <span class="second-part">Start your</span>
                    <span>Journey</span>
                </div>
                <p>Some text goes here</p>
            </div>
        </div>
    </div>
    <!--/Page sidebar-->

    <!--Page main content-->
    <div class="page-main">
        <!-- services wrapper -->
        <div class="vertical-folio">

            <!-- services Item -->
            <div class="vf-item tj-hover-3 set-bg inview-animate inview-fadeleft">

                <img src="assets/img/portfolio/horizontal/city1.jpg" alt="alt" class="img-responsive">

                    </div>
                </div>

                        <h4 class="subtitle">0 %</h4>
                        <br/>
                        <a href="startjourney.html#" class="btn btn-toranj alt">Start Journey</a>
                    </div>
                </div>
                <!-- /Item Overlay -->

            </div>
            <!-- /services Item -->

        </div>
        <!-- /services wrapper -->
    </div>
    <!--/Page main content-->

</div>

问题是只有“页面”中的内容可见，其他所有内容都是隐身的，如下面的屏幕截图所示：

据我所知，代码也正确加载，Javascript插件会导致吗？如何正确加载代码？

我希望有人可以帮助我。 格尔茨，
