dateInput Question
Locked
 
|
Hello All, I was wondering if you could help me understand something. I’m trying to add a livecallback to dateInput. It
works fine but since I have a liveCallback now the regular callback doesn’t
work. I’m trying to understand the following code: canvas hiddenInput callback: [value
:= Date newDay:
(day min: (Date daysInMonth: month forYear: year)) monthNumber:
month year:
year. callbackBlock
value: value]; close. canvas
forgetCurrentBrush. It all makes sense except the part of what triggers the
callback in the first place. Can someone point me to how this hiddenInput
callback is triggered? I’d like to modify my liveCallbackYear: to
call this code and the regular callback code and then my liveCallback block. Ultimately I’m trying to have a date with a field next
to it that shows age. If you change the age it changes the date, and if
you change the date it changes the age. I have the age updating the date
just fine. Now I need the date changes updating the age. Thanks for your help! Ron Teitelbaum _______________________________________________ Seaside mailing list [hidden email] http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside |

Hi Ron,
You do not provide enough background information. Are you using Squeak or VW ? Are you using SeasideAsynx of Scriptaculous ? Since you are refering to liveCallback, it looks as if you are using SeasideAsync. Also, the code you are wondering about is using the canvas api. However, live callbacks are not implemented (yet) for the canvas api. Are you implementing it ? Did you copy/paste some code into your component ? Regular callbacks are triggered by the submission of the form. i.e. click a submit button, hit the return key, execution of a submit() javascript. Therefore you need a form if you want regular callbacks triggered. The dateInput composite is made up of four html elements a select for the month, an input for the day, an input for the year and the hidden input, each with a callback. The first three callbacks are for collecting the input values. The fourth callback assembles the input values into an instance of Date and passes it to the component callback.

Yes I added the following: liveCallbackYear: liveBlock | uri id | liveBlock fixTemps. id _ self ensureId. uri _ canvas urlForLiveAction: [:event :h | liveBlock value: event value value: h]. self session addLoadScript: 'liveSearch(' , (id asString, '-year') printString , ',' , (canvas encode: uri asString) printString , ')'. >> Im trying to understand the following code: >> canvas hiddenInput >> callback: >> [value := Date >> newDay: (day min: (Date >> daysInMonth: month forYear: year)) >> monthNumber: month >> year: year. >> callbackBlock value: value]; >> close. >> canvas forgetCurrentBrush. > The dateInput composite is made up of four html elements > a select for the month, an input for the day, an input for the year and > the hidden input, each with a callback.

I can see that it creates the date but what triggers the hiddenInput callback? It appears to work without submitting the form. Thanks for your help!

Hi Ron,
Now, I see what you are trying to do, you are trying to implement a SeasideAsync missing piece. Actually, I have had a for a long time, the project of finishing SeasideAsync, adding live callbacks to radio buttons, date and time input and maybe a few other smaller things. If found it not trivial and I gave up. I will look if I can restart this project and let you know. Cheers, Michel.

I've currently got some new code I wrote the other day for doing liveCallbacks on Select lists and of course it works great, but I'd be interested in hearing what I should shy away from..

I see I was wrong the callback is triggered by the request of the form post
on the callback stream. So it looks like the hidden field is just a place to put the callback on, but is not actually used in the form itself. Is that right?

Thanks! I just committed a new version of SeasideAsync that has reasonable support for date/time input and for radio buttons. As you can imagine, I will not be able to provide you with a list of what is missing. There are so much things that are not implemented. However, if you give me a list of the things you need, then I can tell you how much it is available. Cheers, Michel. _______________________________________________ Seaside mailing list [hidden email] http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside |

Ron,
I committed SeasideAsync-mb.49 to squeaksource. It has support for date/time input and radio buttons. It requires the most recent version of Seaside2.6b1 (-mb.117). You may want to give it a try like this. html dateInput value: date; liveCallback: [:value :renderer | date := value. etc. ] The live callback receives a Date instance from which you can get the date for computing the age. Make sure you pay attention to the comments I placed in the SeasideAsync package regarding upwards compatibility. SeasideAsync is now using its own renderer (one for canvas and one for classic) and the javascripts are in a separate library. In Seaside2.6b1-mb-117 date input supports a new configuration method #options: that allows you to control the order and the presence/absence of the three date elements (day month year), for instance html dateInput value: date; options: #(day month); etc. Cheers, Michel. _______________________________________________ Seaside mailing list [hidden email] http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside |

That is fantastic! Thank you very much for doing it. I'll look at it right

It works beautifully, thank you very much! It was exactly what I needed.
