Refreshing parts of a web site

[John]

Hi,

Is there any way to update only a single object on a
web page (without using frames)? For instance a
picture that will change on a server depending on
some (server-side) state, for example the weather.

Just like an entire page can be refreshed, I want to
refresh just an image. It's ok to use XHTML or Java
script, although I don't know how to code it right now.

Regards,
John

AJAX script that checks the server every X minute and change the content of a
div if there is a change.

Thanks. I found and modified a JavaScript that updates a div tag. But
right
now I activate the JavaScript function that posts the form to the CGI
script
with a button. How can I make a script that lies in the background and
calls my JavaScript update function once every minute or so?

Whatever the div-update code is, make it a function [say "divupdate()] and
do something like this

function repeatdivupdate() {
setInterval("divupdate()", 60000)
}
repeatdivupdate();
