Iterating over a collection of tags

I think I have a basic misunderstanding of the JsProxy object. What I want to do is the following:

tmp1 := 'p' asJQuery.

tmp1 do: [:each| each - some action -].

However, tmp1 reports DNU for 'do:'.

How can I convert the object that asJQuery returns into something which I can use do: select: collect: etc., on?

Cheers

Array has do:, but jQuery object is not an Array for amber, use

tmp1 toArray do: [....]

Great, that fixes it.

In order to go from the jQuery object to an OrderedCollection, I seem to have to do the toArray, and then asOrderedCollection. There is no way to do this in one step, is there?

In Amber, OrderedCollection is just an alias for Array (which is wrapped
javascript Array).
No need for asOrderedCollection at all.
