[Javascript] Wacky unterminated string + alert + IFRAME error....

Mon May 7 16:24:26 CDT 2001

In this latest rev, yes -- I accidentally left a ">"
from the quoted response.  The actual line is (with
e-mail added line breaks):

ilSrc = 'javascript:document.write('+qt+'<script
language="JavaScript">alert("works!");</script>'+qt+');';

I tried the eval() trick, to no avail.  I also tried
escaping the "/", as well as replacing it with a 
variable (var sl = '/';), but neither helped.

Any thoughts on why this happens when I don't have the
alert('isIE'); call, but doesn't when that call is
commented out?

	Thanks!
