wich one to use for form validation javaScript or jQuery ?!?!

Question

javaScript jQuery

Answer 1

Both, but stay away from framework if your project is small, they are not necessary.

Answer 2

you don't need jQuery for just form validation.

use HTML5 "required" attribute with appropriate input types. although you need javascript for complex validation

Answer 3

There is nice tutorial for form building, validating and processing on w3schools.com. However, it is shown for backend purposes (fetching data from db) so a lot of it is done in php.

For frontend only, if it is just form validating you can do it without framework as someone alredy mentioned.
