for (i = 0; i < ARRcookies.length; i++)
{
x = ARRcookies[i].substr(0, ARRcookies[i].indexOf("="));

It depends on your browser. Chrome e.g. doesn't allow cookies for local files. see: where cookie saved for local HTML file
这取决于您的浏览器。例如，Chrome 不允许本地文件使用 cookie。请参阅：为本地 HTML 文件保存 cookie 的位置

This will work locally
这将在本地工作
// save data value
localStorage.setItem("name", "John");
// retrieve data value
var name = localStorage.getItem("name");

As an alternative to loading the page from file, you can run a webserver and load the page from localhost. Apache comes with OSX and Ubuntu. Once you have set that up you will be able to use cookies on the local page.
作为从文件加载页面的替代方法，您可以运行网络服务器并从本地主机加载页面。Apache 带有 OSX 和 Ubuntu。设置完成后，您就可以在本地页面上使用 cookie。
