Script Error

[JA]

Hi,

I have this JavaScript that is supposed to show random products from my
database, and show something different every time you refresh or revisit.
But I keep getting an error - on my computer - that says Syntax Error in
Line 2.

There is no error on most other computers, and the products show, but
another script on the page, an article title scroller, stops - on most
computers, but not all. It says "no articles available".

I've tried the script on an asp page and a htm page, all by itself, but it
still doesn't work. I tried changing all kinds of settings in my browsers,
but nothing helps. I'm on XP, SP2, which I've heard has some problems
handling javascripts. I don't know if that's true, but if it is, I know that
lots of other people will have the same problem as me when they view the
page. Actually, I think it is a good thing, that my computer is pointing out
this error. I get the error message in IE6, but in NS8 and FF, I just don't
see the products. No error message.

Anyway, here are the first three lines of the script:

<%
if TRIM(request.se rvervariables(" http_referer")) = "" then
%>

Using spellcheck, I found that referer is spelled wrong, it should be
referrer. I don't know if that is right for javascript (or asp?), but
correcting it didn't make a difference.

The script is JavaScript on an asp page, and it is called in an htm page.

Is the error obvious from the 3 lines?

Thanks for any help,

JA

"http_refer er" is blocked by many firewalls; (e.g. Norton).

Re: Script Error


I have Zone Alarm, would that do it? Also Norton Anti-Virus.

What can be done about it? What can it be changed to that wouldn't get
blocked?

Thanks, JA

This looks like ASP/VBScript, not JavaScript. If your browser is reporting
an error on line 2, then its line 2 of the output that the browser
receives, not line 2 of the program that generates the output.

http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html

The Referer[sic] request-header field allows the client to specify, for
the server's benefit, the address (URI) of the resource from which the
Request-URI was obtained (the "referrer", although the header field is
misspelled.)

For security reasons, when you post a reply etc, the site checks that you
have actually come from a page on the forum using what is called a
HTTP_REFERER. This ensures that database entries can only come from the
right page, and stops any external scripts (and would-be-if-they-could-be
hackers)from entering info from souces OTHER than the forum reply page
itself.

Unfortunately, some firewall and web filtering software, such as some
versions of Zone Alarm, block HTTP_REFERER's by default.

# Disable WebWasher Standard Filter/URL Filter
# Disable any "ad blocking" software
# Disable any Pop-up blockers

----------------------------------------------------------
Zone Alarm Pro:

1. Click Privacy
2. Click Cookie Control
3. Click Custom
4. Uncheck "remove private header information"

Use request.serverv ariables("HTTP_ REFERRER")

BTW this is VBS

That looks more like vbscript which only works on Internet Explorer and
servers which allow it.
Also, don't forget the "end if". You can only omit it when the if/then
statement is all on one line.

eg:
if {condition} then {do something}
if {condition} then
{do something else}
end if

As for the spelling of "referer", try this link

"vbscript which only works on Internet Explorer"
This would be true if it were client-side script.

ASP runs server-side.

[Danny@Kendal, posting from home]

Next you'll be telling me that PHP and MySql are server-side as well. ;-)
