[Links checked February/10/2017] User’s input can be validated on the server and on the client (web browser).
A common way to mark required fields is with an asterisk (*).
The first and most obvious information that should be validated is required information – information without which operation cannot be completed successfully.
Thus, validation has to ensure that the user provided all the necessary details in the web form and it has to fail if at least one of the fields is not provided.
On the other hand, users will have to fill in the information without getting a response until they submit the form. Validation in this context refers to validating rules such as username availability.
You can read more about validation with Ajax in this excellent tutorial on j Query For Designers.
Validation is being handled in Java Script methods that you create (or within frameworks/plugins) and users get immediate feedback if validation fails.
Main drawback of client-side validation is that it relies on Java Script.This can be useful to you when deciding on required fields.Apart from ensuring that users provide necessary information, validation has to ensure that users provide information in the correct format.Ideally, users will fill the web form with necessary information and finish their job successfully. In this article we will go beyond the validation itself and explore different validation and error feedback techniques, methods and approaches. The goal of web form validation is to ensure that the user provided necessary and properly formatted information needed to successfully complete an operation.By combining server-side and client-side methods we can get the best of the two: fast response, more secure validation and better user experience.
