passing attributes to events

[acivitillo]

Is it possible to pass on additional attributes to events?

def handle_click(event):
  print(event["target"]["value"]) #<- returns KeyValue Error

html.a({"onClick":handle_click", "value":"somevalue"})

The value attribute seems to work only with certain elements like html.input, but not for others like html.a.

IDOM serializes event information here. Then, for attributes of an event target that get serialized, those are handled here. In the case of the value attribute, it's only present for the following element types:

• BUTTON
• INPUT
• OPTION
• LI
• METER
• PROGRESS
• PARAM
• SELECT
• TEXTAREA

If there's any missing event or event target information that should be included I'd be happy to take a contribution to fix that.

It does not. That should be added though.

Should be pretty easy to grab it

OK, switched to the button element for now. @Archmonger the data-* is exactly what I was referring to now that you make me think about it.

I've created an issue for it.

• Serialize Data-* Attributes #634

Developing that is lower down on the priority list though, since there are workarounds for this.

If you want to see this feature sooner rather than later you could contribute a PR!

I understand the priority is not high, with some styling using button instead of anchor works quite ok as a workaround.

I am not sure I am able to contribute just yet, only docs, for now, I am still getting familiar with IDOM by writing a demo app.
