This ought to be possible with event destructuring: https://hyperscript.org/docs/#event_destructuring The htmx docs say that the value of showMessage in your case is put in the event.detail.value slot, and the hyperscript docs linked above say that you can destructure properties found either on the event or on the event.detail properties. So it should be possible to use the syntax 'showMessage(value)' (or maybe 'showMessage(detail.value)') in your hyperscript.

Good luck! Hopefully some of the points in my post were helpful (though I'm sure you'll have encountered plenty of new and exciting problems of your own) ;-)

Absolutely, and bear in mind this is just a small personal project where my main focus is on the Django ORM and back end. I'm sure the hypermedia approach could be used to build more accessible UIs, but as you say it would need wider community adoption and concerted effort to get there.

Thanks Lakshmi. Stay tuned for the next article, where I will use htmx & hyperscript to add interactivity and partial DOM updates with no JavaScript!
