Try I think this will work.

function onSubmit() {
var firstName = g_form.getValue('field_name').length;
var lastName = g_form.getValue('field_name').length;
var result = firstName+lastName;

    if(result > 15){
		g_form.showFieldMsg('Enter less than 15 characters ', 'error', true);
		return false;
	}
}

and you can use different type of messages through scripting
