Is it possible to write a custom javascript validation in outsystems, if so how?
I am using outsystems 9 on javastack.

At present i am looking to write custom validation on the form as the present validation messages are very generic at espace level.

Also, is it possible to integrate Jquery validation framework to outsystem forms?

Appreciate your help, 

Hi Thirupathi,

Yes it is still possible to do client-side custom validations. Check this component to see how to do it.
Not sure if it is possible and easy to integrate the jQuery validation framework with outsystems forms... You would have to hook it up using the same api used in the forge component above.

Thanks Andre!
Is there any documentation on understanding the client side validation framework of outsystems?

Unfortunately there's only the post you already found.
