I write a JS library component which is applied to every form on a
webpage. The component does something before it submits the form. Now,
let's say user has his own onSubmit() handlers returning true or
false. I want to find a way to add my component's "onsubmit" event to
the form without overwriting user-defined onSubmit() handlers or
onsubmit events.
Is there a really good way of doing this?
The problem I've come across was if I add onsubmit event to the form
which returns false (form should not be submitted), the user-defined
onSubmit() handlers or onsubmit events may return true and submit the
form. I want to prevent it with logic:
....if any onsubmit handlers/events allow form submission but my
component does not allow submission, then do NOT submit the form.
Thanks.
