How to get value of slider in onChange handler?

[jmjpro]

The SyntheticMouseEvent sent to the onChange handler has a target of div. That div doesn't contain the hidden element used to hide the slider value. As such, there doesn't seem to be a normal way to access the slider value in the event handler, which I need to do to update my state. Do I have to resort to refs?

That's related to #2957 and #2883.

@oliviertassinari, you're not saying this is only a documentation issue are you? Is there some way I can use Slider as-is to get the value?

[oliviertassinari]

Can't you use the second parameter? I think that the callback looks like this: onChange(event, value).

[jmjpro]

yes got it now. thanks!

FYI neither the event nor the value includes the field name so I have to pass that the name as yet another param :-(

I have to pass that the name as yet another param

Indeed, why is this bad?

@jmjpro - you could also use a ref.

[jmjpro]

with normal events the name is a field in the event.target object. not the case here since the event.target is a div instead of the backing hidden input element.
