Andy, I don't think you understand how cflocation works. Even though it is a
CF tag, the relocation does NOT happen on the server side. If you make a
test file and place the following code in it:
alert('test');
http://www.yahoo.com";>
. and then hit that page, your browser will make two requests. The first
request for your test page will come back looking much like this HTTP
response:
=
HTTP/1.1 302 Moved Temporarily
Date: Fri, 05 Sep 2008 03:04:33 GMT
Server: Apache/2.2.4 (Win32) JRun/4.0
location: http://www.yahoo.com
Keep-Alive: timeout=5, max=100
Connection: Keep-Alive
Content-Type: text/html; charset=UTF-8
Content-Length: 6551
alert('test');
=
Notice that the output of your page (the JavaScript) DOES get passed out to
the browser. However, your browser (Internet Explorer at least) will ignore
the body of the response and send out a second request for
http://www.yahoo.com.
So whether or not the code is in a CFC or not, the browser is who actually
does the redirect. Of course, if one wants the JavaScript to execute BEFORE
the redirect, you want to send back a 200 response like so:
alert('test');
document.location.href = '<a rel="nofollow" href="http://www.yahoo.com">http://www.yahoo.com</a>';

It doesn't when you use CFLOCATION. It's essentially the equivalent of setting a 302 status code, a Location header, then using CFCONTENT with the reset="yes" attribute. -- Justin Scott, http://www.tlson.com/ ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;203748912;27390454;j Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:312043 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
RE: Javascript in CFC
CF runs on the server, before the Javascrtipt would even have a chance to
hit the browser.

What's wrong with the following code?
...
Alert("Error");
http://#CGI.SERVER_NAME#/testfile.html";>
It's not showing up alert box, directly displaying the html file.
Thanks

First thing is that CFLOCATION sets a 302 header which tells the browser
to redirect, and none of the "output" is sent to the browser.
If you want to show an error and redirect, you'll need to do it all in
JavaScript (also, alert should be all lower-case)...
alert("Error");
document.location.href = '/testfile.html';
