Cookie Plugin |jq-cookie.js| Use

1, set up a one or two-level domain name sharing cookie: Set domain as a first-level domain name, can secondary the domain name common cookie

$.cookie (' f_city ', ' Beijing |101010100|, Jinzhou |101070701| ', {expires:999, path: '/', Domain: ' weather.com.cn '})

2. Delete cookies with different domains of the same name (in one page. weather.com.cn and www.weather.com.cn domains, there are f_city this value, how to delete any of them)

$.cookie (' f_city ', null,{path: '/'})   //Delete the F_city$.cookie under the current domain www.weather.com.cn domain (' f_city ', null,{path: '/', Domain: ' weather.com.cn '})   //delete. f_city under weather.com.cn domain

3. Read Cookies: $.cookie (' f_city '), when reading the value of a cookie key value of f_city, if there are multiple f_city under different domains, read the first f_city value created, and not domain-independent

var cookie_f_city= $.cookie (' f_city '); The read cookie has only one notation and does not accept the {domain} parameter, that is, read-only creation of the earliest f_city when there are parameters with the same name as the domain
