Custom events with underscores do not work, right?

[pohlt]

When I use $dispatch I often split multi-word event names with underscores. For some reason, this doesn't work.

Here's a test page.

Is this a limitation of alpine.js or a general JavaScript/web limitation?

Cheers! 🙏🏼

You cannot add event handler in HTML with underscores _ as it will not compile.
However, you can do it through JS of parent component:
If you want to handle an event in HTML of parent, you should directly add prefix in attribute on event.

I would recommend not to create event-types with underscores as it may not even be supported from javascript in future releases

Would it make sense for alpine to issue a warning or just crash if a $dispatch gets an event with underscores?

Isn't it just because the _ is missing from the reg exp? https://github.com/alpinejs/alpine/blob/main/packages/alpinejs/src/directives.js#L171

I don't think there's a reason why it shouldn't be allowed. As far as I know, there are no restrictions in the HTML specs about underscores in events and attribute names

Is there any way around this at all? I'm using Gravity Forms and all of the events it fires (e.g. https://docs.gravityforms.com/gform_confirmation_loaded/) include underscores
