I'm aware that I could simply override the SaveAction, and provide my own validation for all of the fields, but is there a way to trigger SharePoint's default form validation without actually submitting the form?
Similar questions have been posted here and on other sites, but I have not yet seen a solution which isolates the form's default SharePoint validation.
It would be beyond helpful to understand how to accomplish this, so that I can both share a working solution for a custom attachments table solution with the community and implement this in a SP2013 on prem project I'm currently working on.
Thanks
