hooking with javascript in the edit post sending process [closed]

Question

I'm developing a plugin for a complex custom field that need some js checks and validation before sending.

Is there a way to hook into the sending process with js/jquery?

Answer 1

I think I found it:

$(document).on('submit', function(){
    alert('submit');
});

it would be useful to block the sending process until the validation is made (wondering about compatibility issues...)
