Without form, validation users may enter the wrong data which causes huge damage to our application so make sure your page always contains jquery validation or any other validation, jQuery form validation.
If I submit a value with no jquery validate form it will insert into the database as NULL, while anyone's want to see the data it will show as null. Jquery validate form submit, ensure users need to fill all the data properly and correctly.
There are plenty of ways you can do the form validation. In this pose, we have used jquery validate form submit before submitting while submitting a form it will check all the data filled or not.
This jquery form validation example is like a common validation for us you can write this validation in your common js file which can reduce the boilerplate code for your application.
