How can I add JavaScript to my form?
In ChornoForms v4 both the Easy and normal Form Wizards have a box where you can enter JavaScript. In the Easy Wizard it is the JavaScript Code box on the Others | JS/CSS settings tab; in the normal Wizard you can click the Events tab and then drag a Load JS action from the Utilities action Group.
In ChronoForms v5 use the JS Code box on the Code tab in the Simple Wizard or, in the form Wizard, drag a Load JavaScript action into the On Load event on the Setup tab.
