Custom validation in SurveyGizmo

SurveyGizmo allows you to add JavaScript directly to a survey page with the JavaScript Action. They use jQuery for survey interaction so that's already loaded on the page and available. Using this feature it's easy to customize a survey page.

One of the possible uses is for custom validation. For example to validate user input in some way that SurveyGizmo does not support out of the box. To do this you could start with the JavaScript below. It hooks the Next button click event and then hides or shows the error message based on a custom check. Note, we use the Next button click event and not the page submit event because that is called even when the Back button is selected.
