Provides a convenient way to manipulate cookies:
Copy Code code as follows:
$.cookie (' The_cookie '); Get cookies
$.cookie (' The_cookie ', ' the_value '); Set cookies
$.cookie (' The_cookie ', ' The_value ', {expires:7}); Set a cookie with time
$.cookie (' The_cookie ', ' The_value ', {expires:7, path: '/', Domain: ' sosuo8.com ', secure:true});
$.cookie (' The_cookie ', ', {Expires:-1}); Delete
$.cookie (' The_cookie ', null); Delete Cookies
Code:
Copy Code code as follows:

caution:needed to Parenthesize Options.path and Options.domain
In the following expressions, otherwise they evaluate to undefined
In the packed version for some reason ...
var path = Options.path? '; Path= ' + (Options.path): ';
var domain = Options.domain? '; Domain= ' + (options.domain): ';
var secure = options.secure? '; Secure ': ';
Document.cookie = [name, ' = ', encodeURIComponent (value), expires, path, domain, Secure].join (');

Does this cookie string begin with the name we want?
if (cookie.substring (0, name.length + 1) = = (name + ' = ')) {
Cookievalue = decodeURIComponent (cookie.substring (name.length + 1));
Break
}
}

return cookievalue;
