However the latter returns the value attribute of the dom node, which is “on” by default.
So what kind of magic is actually happening under the hood?
Is Observable just treating inputs differently and using value for everything else?
Resetting the value and firing an input event doesn’t actually change the value propagated to the cells depending on it, probably because it’s fired on the input cell, and not on the stdlib Generators.input object.
Is it possible to access that object directly? Should Generators.input register an input event listener on it’s wrapped value? Thoughts?
Yeah, so the .value is just the default case.
However then I’d actually argue that Generators.input has a bug, in that it should also listen for “input” events.
Yes one could emit a ‘clicked’ event for checkboxes e.t.c. but that feels like a weird API violation, no? I mean ideally instead of using ‘value’ observable would probably use a Symbol('value')
to prevent data transparency issues, but I guess that’s too late now .
Btw, while I got you on the figurative phone, there’s a small bug in Mutable Forms / Fabian Iwand / Observable where it breaks for checkbox with just a single value. I haven’t tracked down the bug far enough, but it looks like browsers automatically wrap multiple checkboxes in a RadioNodeList but leave single checkboxes as is.
Yay auto unwrapping -.- .
As far as I recall there are some problems with input events on checkbox elements, specifically that the checked state will still have the old state when the event is raised. However, you can work around the issue by wrapping your element in a span or div and either have the input event bubble, or trigger it directly on the wrapper.
Ah yeah you’re right.
Normally I really appreciate observables “nothing in-between” approach, but I think in this case it would have been fine to add a bunch of shim methods to input elements the moment they are passed to Observers.input, which abstract away the different behaviours and package them into one neat “input” event and Symbol(value) attribute.
