Edit-text widget

Consider the below macro.

It gets a filter and a JSON tiddler and adds all tiddlers from filter output to the JSON tiddler.

\define sl-macro(filter,tiddler)

<$button set=<<stateTid>> setTo="hide"> Select all

<$list filter=<<__filter__>> variable="Item">

<$action-setfield $tiddler=<<__tiddler__>> $index=<<Item>> $value="selected"/>

</$list>

</$button>

\end

No consider the below example

It has a textbox to get a filter from user and then call sl-macro

<$edit-text

tiddler="state/myExmp"

tag="input"

default=""

placeholder="filter search"

/>

<$macrocall $name=sl-macro filter="[subfilter{state/myExmp}]" tiddler="state/Myselection"/>

This works fine! My question is when I change the filter in a text box and try to add new set of selected tiddlers,

still the previous selection is there (in the JSON tiddler) I use the selected tiddler somewhere else for further processing!

Is there any way to detect the new filter in the textbox and remove the previous selection from JSON tiddler?!

Attached is a sample tiddler of above question to simple test on tiddlywiki.com!

For example try

"[tag[About]]" and then enter "[tag[Android]]".

I know pressing Add all has a button and you clear the previous list! But here my question is to remove previous selection on

filter change in editbox!

Try this sl-macro. "Setting" an index without a value deletes that index.

```

\define sl-macro(filter,tiddler)

<$button set=<<stateTid>> setTo="hide"> Select all

<$list filter=<<__tiddler__>> variable="Remove">

<$action-setfield $tiddler=<<__tiddler__>> $index=<<Remove>> />

</$list>

<$list filter=<<__filter__>> variable="Item">

<$action-setfield $tiddler=<<__tiddler__>> $index=<<Item>> $value="selected"/>

</$list>

</$button>

\end

```

Actually, thinking about this you might want to follow the $:/AdvancedSearch pattern.

Store the output of the filter in a  $:/temp/* tiddler, and display those results in a list for the user.

Then have the button use the $:/temp/* tiddler as the source to clear/update the JSON tiddler.

Then the displayed list will auto-update as the user changes the filter, but it is up to them to confirm the new selection into permanent storage.

Best,

Thanks Joshua,

Yes, its possible to have a button to update the list.

I though if there is a way to detect the change in filter as textbox is updated!

This needs kind of action attribute which seems is not available in edit-text widget!
