Java Script <> Ruby array transfer

[tomasz]

Hi all,
I have heard it is possible to transfer JS arrays to Ruby and back.
Could someone show me how to do it, please?

<script language = "JavaScript">
tellSketchup(list)

function tellSketchup(value) {window.location='skp;ValueChanged@'+value;}

'list' is an array. It is being passed to tellSketchup function.

dlg.add_action_callback("ValueChanged") {|d,mats|;puts mats.class;dlg.close}

Code above returns string.

Everything needs to passed as a string. See the link.

Thanks Jim for such a fast response! I was sure I have seen a video from SU API conference by Google and they mentioned arrays as well.. but it seems I am wrong.

EDIT:
On the same page I have found following :

Looking ahead: Using JSON for more complex data....It's a way where you can pass nested objects and arrays in a single command.

Yes, JSON is how you do it.

I was just looking at ruby-json. I noticed there were 2 ways to use it: one c-language extension, and one called "pure". Unfortunately, the "pure" is not so pure. It requires platform specific libraries also.
