On Qualtrics, how to save embedded data with javascript (given that qualtrics has recently been updated and an old SO solution no longer works)

Qualtrics uses two survey engines: the older SE and the newer JFE. Qualtrics Support was referring to JFE. You can force Qualtrics to use SE by adding the parameter Q_JFE=0 to your survey link. That might be a quick fix.

That said, adding an event listener to the NextButton has never worked reliably with either SE or JFE. Qualtrics has its own event listeners on the Next Button that interfere. The most reliable method is to use JavaScript to hide the NextButton, then add your own button that performs any process you need, then at the end clicks NextButton. See example here.
