How to access index in rv-each?

[trollkotze]

The documentation says under "Differences from rivets.js":

Change how scope of iteration binder works. Instead of copying properties down to children, uses a prototype like approach

Issue 551 and pull-request 552 from rivets.js, which are referred to here, talk about this feature, but it's not clear how (and if) it is implemented in tinybind. The rivets.js generic { index } does not work, nor the other syntax { %item% } that was later added in rivets.

Is it possible to access the iteration index inside rv-each in tinybind?

[trollkotze]

Oh, I found it. The syntax is {$index}.

Found it in the example.

But what about nested indexes? Rivets.js has this syntax now:

<ul rv-each-whatever="items">
  <li>{ %items% }: whatever</li>
</ul>

The index of the iterated array items here can be accessed with { %items% }. In this way, it is possible to distinguish indexes of nested rv-each iterations.

Is something like that also possible in tinybind?

[trollkotze]

Oh, I see. That's how it works:

<ul rv-each-whatever="items" index-property="something">
  <li>{ something }: whatever</li>
</ul>

Would be worth documenting, I think.
