section):
function setCookie(name, value, expires, path, domain, secure) {
var curCookie = name + "=" + escape(value) +
((expires) ? "; expires=" + expires.toGMTString() : "") +
((path) ? "; path=" + path : "") +
((domain) ? "; domain=" + domain : "") +
((secure) ? "; secure" : "");
document.cookie = curCookie;
}
Where:
name
- name of the cookie
value
- value of the cookie
expires
] - expiration date of the cookie (defaults to end of current session)
path
] - path for which the cookie is valid (defaults to path of calling document)
domain
] - domain for which the cookie is valid (defaults to domain of calling document)
secure
] - Boolean value indicating if the cookie transmission requires a secure transmission
Notice how we check for argument existence. For example:
((expires) ? "; expires=" + expires.toGMTString() : "")
The test is done by evaluating expires
, by enclosing it in parentheses. If it exists, then we add the string "; expires="
, and the value of expires.toGMTString()
, to curCookie
. Otherwise, if expires
is not present, we add a blank string to curCookie
.
