示例代码：

$(function () {

    $.scrollUp({

        scrollName: 'scrollUp', // Element ID

        topDistance: '300', // Distance from top before showing element (px)

        topSpeed: 300, // Speed back to top (ms)

        animation: 'fade', // Fade, slide, none

        animationInSpeed: 200, // Animation in speed (ms)

        animationOutSpeed: 200, // Animation out speed (ms)

        scrollText: 'Scroll to top', // Text for element

        activeOverlay: false, // Set CSS color to display scrollUp active point, e.g '#00FFFF'

    });
