Example Login + Captcha Extjs

Posted on: 4/08/2009 08:17:00 PM by Koharudin

Label: , , ,

A CAPTCHA or Captcha (IPA: /ˈkæptʃə/) is a type of challenge-response test used in computing to ensure that the response is not generated by a computer. The process usually involves one computer (a server) asking a user to complete a simple test which the computer is able to generate and grade. Because other computers are unable to solve the CAPTCHA, any user entering a correct solution is presumed to be human. If you want to get more info about captha click Captcha . Ok, related to that I’ve been customized my form Login Extjs with Captcha. If you did not know what Extjs is, you can read first my previous article talked about Extjs here or you can go to Extjs official site here. Ok, this form login does not use database but only static comparation. You can modify with database connection related with your program.
