引入skrollr.min.js插件：

<script src="js/skrollr.min.js"></script>
<!--[if lt IE 9]><script type="text/javascript" src="js/skrollr.ie.min.js"></script><![endif]-->

调用skrollr：

var s = skrollr.init({
    //edgeStrategy: 'set',
    easing: {
      WTF: Math.random,
      inverted: function(p) {
        return 1 - p;
      }
    }
});
