Tony
I'm not sure if I am understanding your suggestion correctly - do you mean
something like this?:
<$edit-text tiddler="$:/state/enter-text" />
<$button>
<$action-setfield $tiddler=myData $index="Key Number" $value={{{
[{myData##Key Number}add[1]] }}} />
<$wikify name=title-value text="<<currentTiddler>> [{{myData##Key
Number}}]/Title" >
...
<$action-setfield $tiddler=myData $index=<<title-value>> $value=<
<currentTiddler>>/>
...
</$button>
Which gives the example result:
{
"Key Number": 3,
"json test [1]": {
"Title": "json test",
"Text": "Here is some text.",
"Date": "21:14, 14th November 2019"
},
"json test [2]": {
"Title": "json test",
"Text": "Blah",
"Date": "21:14, 14th November 2019"
}
}
