Subject: Re: Access array data - problem

Maybe Marcus and Murphy...

Im using Ruby with Sketchup (Googles free drawing program).

In Sketchup its possible to make a webdialog which use html/JS which 
communicate with Ruby via a callback function.

In the webdialog I define an array in html/Javascript like this:

var layer_array = [108,190,95];

in Javascript it works fine with:
Alert("layernum: " + layer_array[0]);
=> output is: ("layernum: 108")

When I send it back to ruby and try:
UI.messagebox ("layernum: " + layer_array);
=> output is: ("layernum: 108,190,95")

But if try this:
UI.messagebox ("layernum: " + layer_array[0]);
=> output is: ("layernum: 57")

Maybe its because it sees it as a plain string as Murpy suggest.

It has to be said, if I define an array in Ruby, everythings work fine. 
It seems to go wrong when send from JS/html to Ruby.

Any ideas how to work around this problem?
