Client Script Types-onChange 3) onChange() Scripts Unlike onLoad() and onSubmit() scripts, onChange() scripts apply to a particular widget on a form rather than to the form itself. They are fired when a particular value changes on-screen. An onChange() script must contain a function named onChange(). For example, here is an onChange() script that notifies the user whenever the short description field on a form changes. 4) onCellEdit() Scripts Scripts can be defined as onCellEdit to run on the client side when the list editor interacts with a cell. This option is available starting with the Aspen release. An onCellEdit() script must contain a function named onCellEdit(). function onChange(control, oldValue, newValue, isLoading) { alert('you changed short description from ' + oldValue + ' to ' + newValue); } To prevent an onChange() script from running when the form loads, add the following to the top of the script. if (isLoading) { return; }
