Modify request data before submit (October CMS Backend forms)

example.js

// Listen to AJAX setup event
// This event is fired before request is formed
// Allows the request data to override input values
// Useful for custom controls, input masks, etc
$(window).on('ajaxSetup', function (e, context) {
	
	// Find the form and inputs from e.target (the submit button)
	// Select specific forms and inputs by modifying $('form') and $('input')
	$(e.target).closest('form').find('input').each(function() {
		var inputName = $(this).attr('name'),
			inputValue = $(this).val();
		
		// Modify inputValue here
		// ...
		
		// Set the modified value
		context.options.data[inputName] = inputValue;
	});
