在jquery中的滚动事件中调用Google Analytics

Question

我在google analytics的母版页中有以下代码。

<script type="text/javascript">
(function (i, s, o, g, r, a, m) {
    i['GoogleAnalyticsObject'] = r; i[r] = i[r] || function () {
        (i[r].q = i[r].q || []).push(arguments)
    }, i[r].l = 1 * new Date(); a = s.createElement(o),
    m = s.getElementsByTagName(o)[0]; a.async = 1; a.src = g; m.parentNode.insertBefore(a, m)
})(window, document, 'script', 'https://www.google-analytics.com/analytics.js', 'ga');

ga('create', '@System.Configuration.ConfigurationManager.AppSettings["GoogleAnalyticsID"]', 'auto');
ga('send', 'pageview');
</script>

我需要在js中调用Google分析滚动事件如何调用Google分析功能进行滚动事件？你能帮我解决这个问题吗？ ？

在我公司工作的人开发了一个与Google Analytics Classic一起使用的库，我使用了Track Scroll插件并将其调整为触发Universal Google Analytics，这里是代码:(如果您有任何疑问，只需问我）

function _get_window_height() {
    return window.innerHeight || documentElement.clientHeight ||
        document.body.clientHeight || 0;

        documentElement.scrollTop || 0;

    bucket = String(bucket) + '-' +
        String(Math.ceil(_max_scroll / 10) * 10);

    ga('send',
        'event',

_trackMaxScroll();
