Bootstrap折叠按钮不适用于智能手机

Question

我试图使用bootstrap collapse类显示div。它工作顺利，但当我尝试使用iPhone，iPad或任何其他“智能设备”上的按钮时，div不会显示。

这是我的代码：

<button type="button" class="btn btn-primary facts-button" data-toggle="collapse" data-target="#watch-facts">    Lees meer </button>

<div id="watch-facts" class="collapse out extras-facts">
    <ul>
        <li>One.</li>
        <li>Two and two again</li>
        <li>3</li>
    </ul> 
</div>

当我禁用此.js脚本时，它似乎可以在手机上运行。不知道问题出在哪里。

啊，最后啊。现在我已经有了完整的代码。我能找到问题。 ： - ）

我在我的机器上本地获取了您的所有网站资源和资产并进行了测试，错误似乎是由于event.preventDefault();在您{.1上提到的.js文件（onepage-scroll.js）上}}

说明： line number 54方法用于防止（不触发）在其中调用事件的默认操作。因此，将阻止您在任何平板电脑或更小设备上触摸事件的默认操作，因此无法在本机设备上运行。

答案：从event.preventDefault功能（第54行）中删除event.preventDefault();，即使在您的原生设备中它也可以正常工作。经过测试，效果很好。

希望它有所帮助。
