scrollOverflow整页

Question

fullpage.js的 scrollOverflow插件在jsFiddle或我的网站上不起作用。相同的代码使用StackOverflow的代码段即可工作。

<script src="https://code.jquery.com/jquery-1.9.1.js"></script>
<script type="text/javascript" src="https://raw.githubusercontent.com/alvarotrigo/fullPage.js/dev/vendors/scrolloverflow.js"></script>
<script type="text/javascript" src="<?php echo THEME_URL; ?>bower_components/fullpage/src/fullpage.js"></script>
<script type="text/javascript" src="<?php echo THEME_URL; ?>js/slick.js"></script>
<script type="text/javascript" src="<?php echo THEME_URL; ?>js/script.js"></script>

$('#fullpage').fullpage({
  navigation: true,
  navigationPosition: 'left',
  // responsiveWidth: 1100,
  scrollOverflow: true,
});
