Hi Folk

Can you please have a look at http://www.friars.co.nz/map.php and let
me know if the map is working on IE6 (just do a simple search).
Unfortunately, I do not have IE6 anymore and so I can not test it.

I think there maybe some trouble with retrieving the AJAX xml. Below
is the code for this:

var i = new Array();
var j = 0;
var jmax = 4;
var http_request = false;


Thanks a million

May I ask _why_ You don't have access to IE 6 anymore?

If it's because you have upgraded to IE7, please check out
http://labs.insert-title.com/labs/Multiple-IEs-in-Windows_article795.aspx
which will guide you in installing multiple versions of IE on Windows
XP.

If it's because you are using Linux, you can install wine, and then
download ies4linux, found at
http://www.tatanka.com.br/ies4linux/page/Main_Page, which will give you
versions 5, 5.5 and 6 all running about as bug free as IE ever ran
before.

All the best.

I just found the problem... IE6 does not like the following line:

http_request.async = false;

So I took it out. The result, however, is that the script does not
seem to wait for one thing to finish before doing the next thing or
something like that. Well, it still works in FF, but not in IE6.
However, there are no errors in IE6.

Can someone tell me what
http_request.async = false;
means.... I think it means "do not process this out of sync with the
rest of the script"

and can someone tell me how to replace it with something more pallatble
for IE6?

Thank you

Hi. Basically it tells the script to wait until it has received all of
the incoming data from the server, or in other words, to run
asynchronously with the server until the server stops sending data (or
in this case, tells the browser it's finished sending data). Otherwise
you are effectively processing data that might not be there, and in
fact, probably isn't.

I believe that for IE, you need to create a new ActiveXObject. As
Microsoft choose to be different, you will need to look into AJAX. This
article should get you on your way.

Best of luck.
