Run a callback function on Caldera Forms submit

caldera-forms-submit-event.js

jQuery( document ).on( 'cf.form.submit', function (event, data ) {
	  //data.$form is a jQuery object for the form that just submitted.
    
    //log form id
    console.log($form.data( 'form-id' ) );
    
    //apply a css to form
    $form.css( {
      visibility: 'hidden',
      display: 'none'
    });
      
});

@TomLeogrande, not quite as familiar with the internal workings of the plugin as a whole. From just the surface, I'd say there has to be a server side PHP filter you could use to clean up that data pre-save.

Our use case was detecting ajax submissions inside a popup, so we could interact with the popups own API to close on submission, trigger a thank you popup, set cookies etc. So I never had to really mess with what happened with the submission server side, just needed to ensure it only processed our stuff when it was a true success.
