Method _ javascript skills

The method and path for specifying the cookie that js can access other domain names are similar. the host name refers to different hosts in the same domain. for example, www.sosuo8.com and blog.sosuo8.com are two different host names. By default, cookies created on one host cannot be accessed on the other, but can be controlled by the domain parameter. the syntax format is as follows:
Document. cookie = "name = value; domain = cookieDomain ";
Taking sosuo8 as an example, to achieve cross-host access, you can rewrite it:
Document. cookie = "name = value; domain = .sosuo8.com ";
In this way, all hosts under sosuo8.com can access this cookie.
