这是在网站的脚本标签内.
var _gaq = _gaq || [];
_gaq.push(['_setAccount', 'UA-18914337-1']);
_gaq.push(['_trackPageview']);
(function() {
var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;
ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);
})();
我不太熟悉Javascript或jQuery.我在一个网站上看到了这个,我想知道它做了什么……
解决方法:
您帖子中的代码是Google的分析跟踪代码.它不是jQuery,它是纯粹的JavaScript. Google在解释跟踪代码的功能方面做得很好.

来自Google的文档引用:
In general, the Google Analytics Tracking Code (GATC) retrieves web
page data as follows:
- A browser requests a web page that contains the tracking code.
- A JavaScript Array named _gaq is created and tracking commands are
pushed onto the array.- A element is created and enabled for asynchronous loading
(loading in the background).- The ga.js tracking code is fetched, with the appropriate protocol
automatically detected. Once the code is fetched and loaded, the
commands on the_gaq array are executed and the array is transformed
into a tracking object. Subsequent tracking calls are made directly to
Google Analytics.- Loads the script element to the DOM.
- After the tracking code collects data, the GIF request is sent to
the Analytics database for logging and post-processing.
