[Seaside] jQuery component rendering by interval

[bobn at rogers.com]

Thank you... seems simple in hindsight ;-)
What I ended up with is...

html div id: 'refreshedComponent'; with: [
self renderSelectedComponentOn: html]

...and...

 self autoRefresh ifTrue: [
html script: (
(html jQuery id: 'refreshedComponent') load html: [:r | 
self refreshDomainData.
self renderSelectedComponentOn: r]; interval: 5 seconds)]

...where #autoRefresh is a Boolean that the user toggles with an "html checkbox onChange: 'submit()'; ... "


Works great. 


Bob

I'm with Joachim. Try something like this:

renderContentOn: html

html script: (
(html jQuery ajax script: [:s | 
s add: ((s jQuery: 'body') load html: [:r | r render: self content ])]
) interval: 5 seconds)

where content is a renderable (ie. a WAComponent ).

hi bob,

I guess you should add to the script a jquery expression that causes some component to be replaced with the contents of the rendering. So either this part is missing in your snippet or it`s really missing. The ajax call is made to re server, but you dont use the results.

Look at senders of load or replace....

Hello,
I am not able to get what would seem to be simple jQuery refresh working. 
The code is supposed to render a component every five seconds. 
I can see the render code being triggered, but the browser display is not being updated.

My code looks something like this... 

html script: (
(html jQuery ajax script: [:s | 
s << (s jQuery html: [:r | r render: self selectedComponent])]
) interval: 5 seconds)

...I do a similar thing in another application using Scriptaculous, which works fine... 

html div 
script: (
html scriptaculous updater
interval: 5 seconds;
on: #renderSelectedComponentOn: 
of: self);
with: [ self renderSelectedComponentOn: html ]

I've been searching through the archives, but all the hits I find make me think the jQuery code is OK.
I imagine I'm missing something obvious... so thanks for any help.
