AcceptUI -Validate underlying form before modal opens

[Scottw12]

I am using AcceptUI modal form . I need to be able to validate the underlying form before calling AcceptUI.  Example at https://dev.heliasfoundation.org/content/forms/donations/annualfund/donate.aspx

Can I call AcceptUI via javascript rather than using AcceptUI as a CSS class?

Is there a call in AcceptUI.js that I can utilize to run a form validation and return a .isValid so the modal opens to finish the transaction.

Thanks in advance

Why not make your own button that validates your form, then simulates 'click' or 'mousebuttondown' or something on thier button?

Has to be a cleaner way out there than that....
