Summary:
Detail:
I have items I shop for every week and I thought I'd create a tiddler to
allow me to uncheck and check items as I shopped.
- I'd like the *state *of the checkboxes to be stored somehow, I'm not
picky where. Simpler may be better.
- I'd like it to pull the list of items from a *DataTiddler*. I think
separating the display code from the data would be nice, and I can also
learn about DataTiddlers at the same time. I'm thinking I don't care if
the state of each checkbox is stored in the DataTiddler or in the tiddler
with the logic. I guess ideally it would be in the DataTiddler, but at
this point if it is simpler I don't have to. I have an example where the
state of each box is stored in the logic tiddler's field, which works.
- If the data could be stored in more of a CSV style, that would be nice
as well, but not essential.
I've done a good bit of searching on DataTiddlers and indexes and have
found some help, but not a lot. Here's some code that gives me what I
want, but obviously I'd rather not have to add more checkbox commands for
each new item I put in the dataTiddler. I know I can loop over this
somehow, right?
But I was unable to find how to successfully loop over the keys in a
Dictionary Tiddler.
This works, but is not dynamic...
<$checkbox field="item1"
checked='val1'>{{ShoppingSamsClubData##item_01}}</$checkbox>
<$checkbox field="item2"
checked='val2'>{{ShoppingSamsClubData##item_02}}</$checkbox>
And here are the contents of the data tiddler....
item_01: Rice
item_02: Milk
