Ooops... here's the real link:

Two ways I can think of to update part of a page without doing a full refresh:

1. Use an IFRAME so you're technically updating a page, but it's the page within the frame (not my favorite but works ok)

2. Or you can use asynchronous javascript (AJAX) to update just that one section of the page without doing a refresh. Here's Rasmus' great primer on AJAX, should be easy enough to follow:

http://www.time.gov/timezone.cgi?Eastern/d/-5/java

One note I'd like to make that doesn't seem to be mentioned in a lot of AJAX tutorials. If the page your AJAX is calling doesn't have the standard "do not cache" tags, you sometimes won't get the results you want.. especially with Internet Explorer (in m
y experience).

Here's a block I copy/pasted from somewhere that seems to work fine (covers most of the bases and all):

header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); // always modified
header("Cache-Control: no-store, no-cache, must-revalidate"); // HTTP/1.1
header("Cache-Control: post-check=0, pre-check=0", false); // HTTP/1.1
header("Pragma: no-cache"); // HTTP/1.0

good luck!

Hi,

No, no that is not what i am after, I know how to do that but it's not what I want.

I wrote some code a year or so ago with words, they refreshed every 5 or so seconds WITHOUT REFRESHING THE PAGE. It was written in JavaScript as i can remember. But I can't find where I did it. I want to have the code or a similar one without the need
to re-write it.

The code does not require the page refreshing at all, just loops in a script and outputs. I might have to do some web surfing on it, pity I can't remeber where it is.

If anyone could help that would be great.

It's for a PHP site using MySQL. I am considering having the slogans in a database this time rather than just a text file.

There is a technique you can use which is actually more "browser"
friendly then the Javascript alternative you mentioned..

You can use the META tags in your page as such:

will refresh page in 10 seconds

CONTENT="10;url=http://www.operation-scifi.com">

will reload page in 10 seconds and direct browser to one of my first
highschool webpages..

For a quick reference I found this via the I'm Feeling Lucky of Google:
http://webdesign.about.com/cs/metatags/a/aa080300a.htm

Otherwise the good ole' W3C at www.w3c.org will have some great doco's
on it too

enjoy ;-)
