Rails - Nov 2006 - stumped trying to escape javascript

So I''ve got a few forms that update info using Ajax and
form_remote_tag.  I''ve got a javascript function that I call from
within my render method in my controller, to take the contents of the
flash and display them in a div that appears and then disappears.  I''m
using the following:


    render :update do |page|
      page << ''ShowMessage("'' +
escape_javascript(flash[:notice]) + ''");''
      ....
    end

however, it fails to work if the flash message contains single quote
characters.

I''ve now tried the following variations:

# works with double quotes, fails with single quotes
page << "ShowMessage(''" + flash[:notice] +
"'');"

# works with double quotes, fails with single quotes
page << "ShowMessage(''" +
escape_javascript(flash[:notice]) + "'');"

# fails with double quotes, works with single quotes
page << ''ShowMessage("'' + flash[:notice] +
''");''

# works with double quotes, fails with single quotes
page << ''ShowMessage("'' +
escape_javascript(flash[:notice]) + ''");''

So unfortunately, I can''t get any of the above variations to handle
both double quotes and single quotes.. I can only get it to work with
one or the other.

If someone can please tell me how to properly escape this, or what I''m
doing wrong, I''d really appreciate it.. This is driving me crazy!
Thanks,

Mike
