[mochikit] Re: Conceptual assistance on periodically updating table contents from database

Hi. New to Turbogears and Mochikit (did I just hear everyone clicking
the back key? :-)
I am teaching myself by doing an in/out sign in board, which I have
gotten to the point where I have a table that I can sort, as well as
update by clicking on the edit button for the inout_status field.
Really think TG and Mochikit are cool
My stumbling point now is how to keep the table contents up-to-date
(showing all the correct inout_status values as people update their
own status) without doing a page refresh.
without doing a page refresh = ajax .
but maybe you already new that ;)
Is there a timer function
(I think that calllater might be it???).
yes, you can use the callLater function,
especially for idea #2, see below.
I have two ideas here:
1) Have TG maintain a variable (change_flag) that the edit button(s)
on all the user screens will set as TRUE when the user changes
inout_status. Each screen could then periodically check for that
change_flag == true, and if so, the table value could all be updated?
2) Just have a timer in Mochikit that would trigger periodic updates
to ALL the table contents.
maybe something like this:
var REFRESH_INTERVAL = 120; //120 seconds, every 2 minutes.
//Warning: dont make interval to short,or you will have unhappy browsers
var updateTableWithNewData = function(res){
//'res is the data from an ajax query for your table data
// insert new data in table logic here *See MochiKit.DOM*
}
var getNewTableData = function(url){
//url is the /path/that/serves/new/tabledata
d = loadJSONDoc(url); //could be 'doXHR' or similar
d.addCallback(updateTableWithNewData);
}
callLater(REFRESH_INTERVAL, getNewTableData);
You will need to start the 'refresh loop' with some 'onload' function as
well.
Hope this helps.

[mochikit] Re: designing netvibes type look and feel
The Netvibes content boxes use background images. The trick is that they use several -- one for the top shaded area and box bounding (no- repeat), one for the bottom (no-repeat again, and includes the drop shadow), and one for the box body (repeat-y). If the boxes/panels are fixed width, it's easy. If you want to make the components width- resizable, then you need to include styling-only elements (that is, elements with no semantic significance that only exist so they can contain background images).

What I am looking for is a square, resizeable glossy looking box (similar to the ones inwww.netvibes.comor pageflakes.com). I do not want them to be movable but it will be great if they are resizeable. Is there a way I can do this using mochikit/any other library? If these are not movable compnents, is it possible for me to develop a similar look and feel (slightly raised, glossy, shaded background etc) using CSS? One option that comes to my mind is making opaque images with the desired look and feel and use them as background images in various DIVs. However, in this case, resizing will be a major issue. I would appreciate any pointers on this. Also, please let me know if there are any libraries that can help me achieve such a look and feel.

[mochikit] Re: Comparing dates
More to the point here, Date() returns a string the way you are using it, not a date object. If you want a date object to compare, use the new keyword. (Date objects can be directly compared with , and =, since they have a single scalar data member and collapse to a milliseconds-after-epoch value on comparison.)

I think it's something to do with the lack of quotes around the result of isoTimestamp - though quite what that means i'm not sure. Please someone help me out, i really need to be able to compare these dates. JavaScript's built-in comparison operators are no good for comparing objects, only strings and numbers. This is why MochiKit.Base.compare exists. -bob --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups MochiKit group.
