You need to include the jQuery cookie pluginbefore this code snippet.
您需要在此代码片段之前包含 jQuery cookie 插件。

Including jquery file twice(multiple time) also gave same issue in my case.
在我的情况下，包括 jquery 文件两次（多次）也给出了同样的问题。

That error means exactly what it says: $.cookiedoes not exist.
该错误的含义正是它所说的：$.cookie不存在。
jQuery core does not include anything related to cookies. There are several cookie librariesthat add a cookiefunction to $. You need to add one to your page first.
jQuery 核心不包含任何与 cookie 相关的内容。有几个 cookie 库可以cookie向$. 您需要先添加一个到您的页面。

It means the library that's supposed to have that function is not loaded. But you can set a cookie using javascript, here:
这意味着没有加载应该具有该功能的库。但是你可以在这里使用 javascript 设置 cookie：
