JS 简单封装的Cookie对象

//cookie

setCookie:function(name, value, expiry, path, domain,
secure){

} 
catch (e) {
if (expiry) {

expiryString = "; expires=" + lsd.toGMTString();
}
}
}else {

(365*24*60*1000).toGMTString();
}
var pathString = (path == null) ? " ;path=/" : " ;path = " +
path;
var domainString = (domain == null) ? " ;domain = " +
gloDomain : " ;domain = " + domain;
var secureString = (secure) ? ";secure=" : "";
document.cookie = nameString + expiryString + pathString +
domainString + secureString;
},

var i, aname, value, ARRcookies =
document.cookie.split(";");
for (i = 0; i < ARRcookies.length; i++) {

1);
