* Cause and copyright description:
1. on the blue ideal, a member posted a similar system, asking that the verification code does not support firefox refresh, so he came up with the idea of doing one. the appearance of the system (button color etc.) draws on the system, but the detailed implementation principle is not the same (the address: http://bbs.blueidea.com/thread-2761325-1-4.html ).
2. In addition, the self-built registration system uses the component-less verification code on the Network (by sipo)
3. As for the password strength algorithm draws on the blue ideal article (http://www.blueidea.com/tech/web/2006/4324.asp), but the algorithm is not very ideal, if there is a better algorithm of friends may wish to exchange
* Features and knowledge points:
1. AJAX verifies the user name and verification code, and asynchronously registers the user name (both of which are basic parts of AJAX)
2. Support for verification code refresh (including in firefox)
3. Real-time password, email address, user name detection (using javascript DOM)
4. HTML is verified by W3C Strict, and CSS is also verified by W3C CSS (in fact, this is a bit redundant and not completely necessary)
* Development Platform: Windows2003 IIS6.0 Access Database
* Tools: DreamWeaver (write ASP), Aptana (write Javascript, HTML and CSS), Emeditor (write this article), Access2003 (database)

* Supplement:
If you use this registration system, be sure to pay attention to the following issues:
The system does not encrypt the password. If necessary, you can search for MD5 encryption.
The system has no anti-injection settings. If necessary, you can search for SQL anti-injection settings.
If you have any questions or suggestions, please contact me. Thank you!
