CookieObject

CookieObject.js

//CookieObject v1 by Andy Pan

// You can use the small piece of code to r/w
// > Cookies, not losing its structure of an object.
// > All complex contents will be automatically
// > en(de)code, but simple contents won't
// > so that you can access them without pain.

// Assume JSON.parse() and JSON.stringify().
// Use it with jquery.cookie by carhartl:
// > https://github.com/carhartl/jquery-cookie

//Manual

// Call cookieObject.init() to read in all.
// This is optional. You can use it normally 
// without doing this. Useful when you only 
// need to use cookie as a cache.

// Once the cookie is read,
// > its form of object will be cached 
// > and be updated when saving it back.

// An alternative way to use is writing the 
// > data into cookie, and manually calling 
// > cookieObject.flush(...). If a key is not 
// > specified, all entries will be flushed.

//To save/load a cookie, simply substitute 
// > $.cookie(...) to
// > cookieObject.save[load](...);

//To-dos
//  * Make it a fallback for localStroage.

//Good luck!
