Anchor appearance when script attached
by Laura Risani 05 Mar '15

05 Mar '15

Hi all, I want to attach a jQuery script to an anchor element while keeping the regular anchor appearance (i mean that web browsers render it like any other anchor, being focusable), and to be triggered under the same conditions a callback would (clicked / pressing a key while having focus). I can attach the script by sending html anchor onClick: aScript; onKeyDown:aScript but then the printed anchor looks on the web browser like regular text and don't get foucs. Best, Laura

Concurrent Programming
by sergio_101 02 Mar '15

02 Mar '15

i am currently writing a facebook application in seaside. one of the most important pieces of data i need to retrieve is the user's friends list. unfortunately, this could end up being a substantial amount of data. fortunately, the load time for this data is not horrible, just a few seconds. i am making the assumption that while interacting with my app, the user will not be adding new friends mid stream, and that during each session, the friends list will be static. what i would like to do is make this happen completely behind the scenes, so that when the user logs in, the request for the friends list is fired off RIGHT AFTER the page is rendered. i read the section on concurrency in 'deep into pharo', and while incomplete, it makes enough sense for me to try it. my question is.. i am going to do something like: [currentUser updateData] fork 1. if i want to do that RIGHT AFTER rendering, can i put that at the end of renderContentOn: html ? 2. when i want to work with the data, how would i know if it was done updating? i was thinking of using a semaphore.. but how would i let the next process know to keep waiting until the process was done? i would want to do something like: getFriendsList (but make sure process that populates it is done before running the request). thanks!

Listening to a comet app
by Laura Risani 02 Mar '15

02 Mar '15

Hi all, I'm trying to set up the listening for a comet app. Following DWDWS book section 22.2 i tried to send WAListenerAdaptor startOn: 8888 . Since it didn't work (i download Seaside manually) i went to Seaside main repo and loaded the last version of package Seaside-Adaptors-Comanche. And it seems to work, but when i point my web browser to the port 8888 i get an error (on ide side) cause a msg is send to the class HttpRequest which isn't loaded on the image. Am i loading the package wrong? Love, Laura

Pass jQuery result to callback
by Laura Risani 24 Feb '15

24 Feb '15

Hi all, I want the following to occur to when an anchor (with href set to ‘javascript:{}’, the issue is that the page shouldn't be re-renderer) is clicked 1°find some information on the rendered html page 2°send it back from client side jQuery allows me to make scripts for both steps (for 1° query methods, for 2° #callback:). My problem is i don't know how to bind these two steps in a single script, since from what i know i can't add and asign to a smalltalk temp inside a script and i can't perform queries from within a callback block (cause the html renderer no longer exists). So, how do i add a temp variable inside the script and how i merge the 3 resulting "step" scripts into one? Love, Laura

Seaside Coding Pattern
by Craig 23 Feb '15

23 Feb '15

Hi All, A pretty-much universal pattern of coding of Web Apps in non-image based languages (C#, PHP, Java) is: * The incoming web request starts a process * some objects are instantiated, usually from a SQL datastore, * some interactions occur with these objects * optionally, some database modifications are made * a response is sent to the web browser * all the temporary variables that point to the objects go out-of-scope * all the objects are garbage collected I caught myself coding a Seaside app using the same pattern and wondered if it's sub-optimal in an image based language. So, is this an acceptable way to code a Seaside app? Should I rather be using long-lived image based objects? Stored in a collection hung off a class variable. Comments would be appreciated. Craig
