Content Header .feed_item_answer_user.js-wf-loaded . A lot of websites now require registration, meaning that users need to be assigned a username and password.Here are some simple steps to make the process more secure.I am trying to build a simple login form with the predefined username and Password and I want to validate user input matches with username & password that I specified.If the user enters wrong username or password I want to display an alert message.The short examples in this section implement common Java Script web database features, and we recommend that Java Script be used only for these simple manipulations and the basic validation tasks.Using Java Script for more complex tasks may reveal annoying differences between browser applications, browser versions, and different platforms.
Pointers to books and other resources on Java Script are included in Appendix E. This book is focused on thin clients, where the majority of the application logic resides in the middle tier.
If the purpose of registration is to confirm that the person exists, and that they have supplied a valid email address, then as part of the registration process you a should email them either: a random password; or a confirmation token.
Do not let them choose their own password and use it immediately without verifying that they exist.
Java Script highlights annoying differences in support of standard features by different browsers.
Even different versions of Netscape or Internet Explorer support different Java Script features.
