hx-on is the general js API from htmx, it's essentially a wrapper/shortcut for creating a js event handler. The htmx docs provide some examples

I had found that. It has the "what" but not the "where or why"

[dgb23]

You mean htmx in general?

The author of htmx wrote a rationale (when and when not to use it). https://htmx.org/essays/when-to-use-hypermedia/

Good article, but I saw no mention of hx-on

[renerick]

Because HTML's on* attributes are not generic, they are hardcoded in the spec, you can't use them to handle arbitrary events. hx-on is an attempt to fill this gap for simple cases, when managing event listeners manually or resorting to _hyperscript or alpine is too much

Yes, I saw that. But what does it have to do with XPath?

[renerick]

XPath is implementation detail, used for searching of attributes with a give prefix, and this article is just a public note of how it was done in htmx

Got it. Thanks.
