Ninja Forms Three - After a form has loaded

nf-after-load.js

// Create a new object for custom validation of a custom field.
var nameSpaceController = Marionette.Object.extend( {
  
  initialize: function() {
    this.listenTo( nfRadio.channel( 'form' ), 'render:view', this.doCustomStuff );
  },

  doCustomStuff: function( view ) {
  	var formModel = view.model; // formModel will be a Backbone model with all of our form data.
  	var formID = formModel.get( 'id' ); // We can use .get( 'setting' ) get get any of our form settings.

  	/*
  	 * We can also update or modify fields now.
     * 
     * If we wanted to change a field value, for instance, and we knew the field key we wanted to target, we'd do something like:
     * var fieldModel = formModel.get( 'fields' ).findWhere( { key: 'your_key' } )
     *
     * If you want to get a field by ID, you'd use:
     * var fieldModel = formModel.get( 'fields' ).get( '99' );
     * 
     * Now that we have our field model, we can modify any of its settings.
     *
     * fieldModel.set( 'label', 'New Field Label' );
     * fieldModel.set( 'value', 'New Value' );
     * fieldModel.trigger( 'reRender' ); // Tells the field to re-draw itself.
     * 
     *
     * You can do this with regular jQuery stuff if you know the ID # of your field.
     *
     * jQuery( '#nf-field-99' ).val( 'New Text!' ).change();
     * 
     * If you change something using a jQuery .val() method, you'll need to call a .change() on the element as well.
