Queries index of value in object array.
Returns zero based index or -1 if not found.
We look into each object in the array, check if it has a value for the given label and compare that to the one to find.

Version 10.0 or newer finds optionally by content, so number can be found via text.


Find item:

MBS( "JSON.FindValueInObjectArray"; "[{\"key\": 1}]"; "key"; 1 )

Example result: 0

Find text:

MBS( "JSON.FindValueInObjectArray"; "[{\"key2\": \"test\"}, {\"key\": 1}]"; "key2"; "\"test\"" )

Find an entry in files array:

Set Variable [ $files ; Value: MBS( "JSON.GetObjectItem"; $content; "files" ) ]
# the string we look for
Set Variable [ $searchFor ; Value: MBS( "JSON.CreateString"; "something/test.jpg") ]
# now look for index in array:
Set Variable [ $index ; Value: MBS( "JSON.FindValueInObjectArray"; $files; "PathName"; $SearchFor) ]
