Understand the spy attribute and get scroll top. about react-scroll

[fisshy]

When a link and an element is linked together with "to" and "name" and spy is set to true, there will be a listener on the scrolling event notifying the link when it's scrolling over that element to make sure it gets highlighted.

There's no scroll top now - maybe this is a good feature to have actually. Might rewrite some of the "scrollTo" logic to make sure it doesn't depend on elements or if someone else feels like doing it :)

Great thanks for the info. So is there an event I can listen to within the element that I could use to trigger an animation. For example click the link.. scroll to the element. When the scroll is complete then an event fires that I can use to trigger another event? Hopefully I am understanding you correctly:)

I can take a look at the code and see if I can make some time for a PR.

Also if I understood you correctly above, if you could share an example of hooking into that event, would be greatly appreciated!

Theres no callbacks at the moment - that's a good feature to have as well actually.
I might do some changes in the upcoming days if nobody else feels motivated to send a PR :)

That would be awesome, I tried to add a window scroll listener and pushed that info into the props and it was non performant visually. If there are callbacks then I can use the scroll event to trigger the animation. There might be a better performing way to handle it, but I haven't figured or come across it yet:)

Should I open another issue request for callbacks?

[fisshy]

Yeah do that, this is possibly something I can solve tonight ;)

[hydrotik]

Ok Will do!
