link to new win & pass cookie val in querystring.

WebCT forces the following new window link formatting:
onclick=”if (! top.in_designer_mode()) { top.doWindowOpen(‘http://www.someurl.com/students/chats/roster.asp?uid=document.cookie.WebCTTicket.username‘, ‘new_frame’, ‘width=730,height=414,menubar=1,toolbar=1,scrollbars=1,status=1,location=1,resizable=1’, 0); } else { void(top.update_breadcrumb(‘test pass querystring to new win’, ”, ‘/SCRIPT/RAD_Orientation/scripts/designer/serve_home?1008260903+edit+1008265122+REORG+1008265122+1’, 0, 1, 1, 0));} return false;”

I use their text box to supply the URL of the link I want their page to point to, eg. http://www.someurl.com/students/chats/roster.asp, and they auto format the new window opener.

I need to pass the username value of their login cookie in the querystring of the above url something like so:
?uid=’+document.cookie.WebCTTicket.username+

Trouble is that they format the new window opener for me as described above with apostrophes and break my link. It ends up being:
top.doWindowOpen(‘http://www.someurl.com/students/chats/roster.asp?uid=’+document.cookie.WebCTTicket.username+’, ‘new_frame’, ‘width=730,height=414,menubar=1,toolbar=1,scrollbars=1,status=1,location=1,resizable=1’, 0). Everything after the uid= is ignored because my apostrophe becomes the end of the URL string.

I want the uid variable in my querystring to hold the username value of their WebCTTicket cookie, but don’t know how to get it in there. Do I need to escape the apostrophe sonehow (I tried and failed)?
