问题描述
有谁知道为什么 Google Analytics 需要两个单独的脚本标签?
Does anyone know why Google Analytics requires two separate script tags?
具体来说，他们的说明建议用户将以下代码段嵌入到网页中以进行跟踪:
Specifically, their instructions advise users to embed the following snippet of code into a web page for tracking purposes:
<!-- Google Analytics -->
<script type="text/javascript">
var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");
document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));
</script>
<script type="text/javascript">
try {
var pageTracker = _gat._getTracker("UA-8720817-1");
pageTracker._trackPageview();
} catch(err) {}</script>
为什么用户不能像这样只使用一个脚本块:
Why couldn't users use only one script block like this:
<!-- Google Analytics -->
<script type="text/javascript">
var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");
document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));
try {
var pageTracker = _gat._getTracker("UA-8720817-1");
pageTracker._trackPageview();
} catch(err) {}</script>
