[TW5] Populating a SelectWidget with the indexes/values of dataTiddler

[Ghislain SILLAUME]

Dear all,

I'm discovering TiddlyWiki since a couple of weeks. It's a fantastic tool but I'm still not able to manage all the 'magic'...

I would like to populate a select box by iterating on this dataTiddler (The indexes are the quarters of a year and the value the corresponding dates for the date of start of the quarter):

Q1/14:20140101
Q2/14:20140401
Q3/14:20140701
Q4/14:20141001
Q1/15:20150101
Q2/15:20150401
Q3/15:20150701
Q4/15:20151001

I did find how to iterate on a dataTiddler [quarters] and display indexes and values here: http://tobibeer.github.io/tb5/#Iterate%20DataTiddler%20Indexes

Unfortunately, it's not working in the context of a selectWidget with the following code (The values of the selectWidget are filled with 'true'):

<$select field="start_date">
<$list filter="[[quarters]indexes[]sort[title]]">
<option value=<$transclude tiddler=[quarters] index=<<currentTiddler>>/> >
<$text text=<<currentTiddler>>/>
</option>
</$list>
</$select>

Any ideas?

Thank you very much for your help.

Best Regards,
Ghislain

Hi,

try:

\define valueFromIndex()
[[data]getindex[$(index_key)$]]
\end

<$select field="start_date">
<$list filter="[[data]indexes[]sort[title]]" variable="index_key">
<$list filter=<<valueFromIndex>> variable="index_value">
<option value=<<index_value>> >
<<index_key>>
</option>
</$list>
</$list>
</$select>

Also, you can't put a widget as an argument to another widget (and HTML-tags are widgets too).

Oh, and don't forget to change "data" back to the name of the tiddler you want it to work on. Both in the macro and in the list filter.

It works perfectly.

Many thanks!

Here's a more compact implementation without any macros:

<$select field="start_date">
<$list filter="[[quarters]indexes[]sort[title]]" variable="key">
<$set name="val" filter="[[quarters]getindex<key>]">
<option value=<<val>>><<key>></option>
</$set>
</$list>
</$select>

enjoy,
