The Source Code of ActionScript 3 Cookie class

D0The Source Code of Actionscrīpt 3 Cookie class–Enables You to Read, Write, and Edit Shared Objects on the User’s Hard Disku*Su#M }j|&uh0

j9~[S#S/[`'[0Have you ever wanted to store persistent information in your Flash movies, save login information, shopping cart data, user preferences, even complex objects like arrays? If you have purchased “Flash Extension”, simply import the cookie class and copy the source code like following:闪吧新社区1u4n6k*k/aM

1. import com.communitymx.Cookie;
2. var myCookie:Cookie = new Cookie(”yoursite”);
3. // user info
4. myCookie.username = “nttlib”;
5. myCookie.password = “abcdefg”;
6. myCookie.save();
7. // retrieve cookie info
8. trace(myCookie.username); // result: nttlib
9. trace(myCookie.password); // result: abcdefg

*SCG:b.B4V9hc _#l0But…Maybe you have noticed the word “purchased”–yes, it is not free! The following is a free, similar above cookie class, using it you can set cookies in flash to remember a user’s music preference now.
