javascript - 不知道cookie的路径是什么？如何找到它？

Question

 function setCookie(name, value)
    {
        var times = 30;
        var exp = new Date();
        exp.setTime(exp.getTime() + times * 24 * 60 * 60 * 1000);
        document.cookie = name + "=" + encodeURI(value) + ";expires=" + exp.toUTCString() + ";path=/";       
    }

“path=/”代表cookie的路径是什么？如果删除“path=/”，cookie的路径是什么？

Answer 1

"path=/" 表示

path is set, you can access cookie name anywhere in your application/domain (http://localhost or http://example.com)

"path=/" 未设置意味着

path is not set, then cookie name is save just for the directory(also include its child directory)
in which current page belongs to, you can't access it on another directory
