Question

我无法在移动浏览器（Safari）中使用此下拉列表我可以知道是什么问题？它在桌面浏览器中运行良好，如Chrome，Safari ..此代码由Adobe Muse生成。

我也在iPhone6 Plus中试过这段代码。

您是否在代码中添加了jQuery库？

尝试在特定脚本标记之前添加它。

 <script src="//ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
    <script type="text/javascript">
 var dropdowns = $(".dropdown");

等...

下拉不适用于移动浏览器＆amp;火狐
