i have a javascript like this:

settings=x+","+y+","+z;
> query = 'skp;_edit@'+settings;
> window.location.href = query;

in ruby:

window.add_action_callback("_edit") {|window,p|
> resultarray=p.split(",")

Now the x, y or z value in javascript can contain commas.
So this will cause problems for the resultarray in ruby.

What is the best way to escape the comma's (or any problem characters in javascript) so they are comming to ruby in a usable way?

If you know that you're going to have commas in the variable values then a comma as a separation character is probably not a good choice. That said, you could first use javascript's escape() on all your variables which will turn every "," in a "%2c" and then join them with your separating ",".

On the Ruby side you can find a "URL-decode" functions in the CGI module:

def urlDecode(string)
    ## URL-decode from Ruby;;CGI
    string.tr('+', ' ').gsub(/((?;%[0-9a-fA-F]{2})+)/n) do
        [$1.delete('%')].pack('H*')
    end
end

Off course the other way arround is also a problem:
ruby

rubyarray=['blablabla,','boem,boem,boem','world']
> #join the array to send to javascript
> rubyarray=rubyarray.compact.join(",")
> command = "_test('#{rubyarray}')"
> window.execute_script(command)

In javascriptI split up the string by comma

function _test(x)
> p = x.split(',');

Same procedure only the other way around. These days I prefer to build a JSON string in Ruby and eval() that on the javascript side for anything that's a bit more complex. In your case that would take car of the the encoding because your rubyarray also works as javascript array.

You won't be able to use HTML5 in webdialogs - not until IE adds support for it.

I am using excanvas http://code.google.com/p/explorercanvas/ which provides a canvas object in IE.
