ga或_gaq.push用于Google Analytics（分析）事件跟踪？

我想跟踪一个网站页面上按钮的 onclick ，条件通过后检查是否存在cookie。

I would like to track an onclick of a button on a page on a site, after a condition is passed checking if a cookie is present.

很简单，但哪种语法最有效？

Very simple but which syntax would work best?

我研究过 ga 和 gaq_push GA事件跟踪语法的前缀（原谅我，如果我错了），但他们看起来很相似？

I have researched the ga and gaq_push prefix of the GA event tracking syntax and (forgive me if I'm wrong) but they seem pretty similar?

_gaq.push

_gaq.push

<script type="text/javascript">
jQuery(document).ready(function () {
    if (jQuery.cookie('entry_winagrand_cookie') !== null) {
        jQuery('notregisterbtn').on('click', function () {
            _gaq.push(['_trackEvent', 'QR_Win_A_Grand', 'Clicked through to Register']);
        });
    }
});
</script>

ga

ga

<script type="text/javascript">
jQuery(document).ready(function () {
     if (jQuery.cookie('entry_winagrand_cookie') !== null) {
         jQuery('notregisterbtn').on('click', function () {
             ga('send', 'event', 'button', 'click', 'QR_Win_A_Grand', 'Clicked_through_to_register');
         });
     }
});
</script>
