无法获取某些 Javascript 的值

我一直在使用Github上的这段代码来收集一些UTM/其他URL参数。

我已经能够成功地将参数保存在 cookie 中，并将这些值传递到隐藏的输入表单中。

此代码通过谷歌跟踪代码管理器加载到网站的每个页面上。

场景：

- Cookie 会话按预期存在于网站的每个页面上。

-主网站位于不安全的HTTP连接上（http://www.example.com）。

-子域上存在安全页面。（https://www.subdomain.example.com）。

问题：在安全的子域页面上，我无法从任何UTM Cookie中获取值。我可以从 VISITERS、IREFERRER、LREFERRER 和 ILANDINGPAGE cookie 中获取值，但不能从 UTM cookie 中获取值。

这是我正在使用的代码：
