Form Validation Using Jquery Examples

When you include forms on your website for user input, it is always advisable to perform some validation on the data entered. This not only ensures that your application receives the type of data it can work with, but it also makes for good UX (user experience) as users will be able to be warned of the incorrect input and be given hints of the kind of data that is acceptable.

There are two kinds of validation: client-side and server-side validation. It is recommended that you perform both. Client side validation is usually done with JavaScript and it serves to give the user quick feedback on input errors before a call to the server is made with the data.

Client-side form validations help in giving immediate feedback to the user. It is also required to add server side form validation in your form processing script. The user can disable Javascript on their server or even auto-bots might try to submit your form as well.
