Yes this is nice, but I thing this is better approach:
in controler:
def getResults():
.
.
return something
in view:
{{=LOAD('sniffer','getResults',ajax=True)}}
Therefore this do not solve my problem :D Actually my previous idea
(periodically update) was bad. Do web2py have capabilities to update
widget only when queue (source of data) changed?
Thanks,
cheers

The simplest solution is that you get generic.load from 1.80.1 and
you
replace
function refreshWidget() {
ajax('refresh_widget', [], 'mywidget');
}
with
function refreshWidget() {
ajax('refresh_widget.load', [], 'mywidget');
}

Thank you very much Adi, but rpoblem is that refreshWidget is called
only once. And after that page looks like in attached screenshot.
My ajax function is here:
function ajax(u,s,t) {
var query="";
for(i=0; i<s.length; i++) {
if(i>0) query=query+"&";
query=query+encodeURIComponent(s[i])+"="+encodeURIComponent(document.getElementById(s[i]).value);
}
jQuery.ajax({type: "POST", url: u, data: query, success:
function(msg) { if(t==':eval') eval(msg); else
document.getElementById(t).innerHTML=msg; } });
}
Cheers Tom.

Some frameworks have active data widgets - the widget updates whenever
data changes. I'm not sure how exactly it can be implemented in
web2py, but something like this should work:
View (.html file):
------------------------
<div id="mywidget">{{=mywidget}}</div>
<script>
setTimeout(refreshWidget, 10000); // calls refreshwidget every 10
seconds
function refreshWidget() {
ajax('refresh_widget', [], 'mywidget');
}
</script>
Controller (.py file)
---------------------------
def refresh_widget():
# logic to generate widget
return dict(mywidget=mywidget)
Explanation:
Every 10 seconds there's an ajax call to controller's refresh_widget,
which generates the HTML for the updated view that you want to show
inside the mywidget tags (like list of elements). This HTML is placed
inside the mywidget tag.
This is the simplest way to solve this problem that I can think of,
and this is not efficient because even if your data has not changed,
you'll still be polling the server every 10 seconds. But this should
work!

Hi all,
Im trying to create widget (lets say list of elements) which should by
updated asynchronously through ajax. I don't get all the ajax examples
in web2py book for example. Those examples only deals with some action,
like on click, on mouse move, on sbutton submit or so. I need something
like check if queue (source of data) have anything to provide or simple
use a timer and reload widget every e.g. 10 sec.
Thanks for advices. Please let me know if anything was unclear/wrong
described.
