This new site (came online 1 Sep) www.quixtar.com has the following
Javascript to test a browser for cookie handling. It doesn't work on
V3 or with Opera 3.21 on a Windows 3.1 notebook. On both it
states that the browser doesn't support cookies or the cookies are
turned off. They're not. I've been told it works with IE. Don't know
about Netscape.
Anyway, V3 generates an JS error: Function Expected.
Here's my questions:
1. I thought JS was traditionally suppose to be in the <HEAD>
section of the HTML code; so why is the code at the very beginning?
Even ahead of the <HTML> tag.
2. It uses 3 library functions to handle cookies. Wouldn't this
library have to be on the user computer for the JS script to work? Or
would it being on the server be sufficient?
Code follows, exactly as saved (Sorry about the >80 character lines):
