Thanks to advice from here (Looping through JSON using ASPJSON) and here (ASP JSON: Object not a collection), I am starting with a JSON array in Classic ASP:
{\"
You could access msg
, which is a json object, within the loop you already have:
For Each thingy In oJSON.data("markers")
Set this = oJSON.data("markers").item(thingy)
Response.Write _
this.item("_id") & ": " & _
this.item("ts") & "<br>" &_
this.item("msg").item("subject") & ": " &_
this.item("msg").item("diag") & "<br>"
