javascript - Classic ASP: how to convert a RecordSet to json notation using AXE json implementation

Question

i'm doing an application with ajax using jQuery and some other tools, and in some part i want to retrieve data with ajax using a classic ASP backend, i saw that exists a good implementation of a JSON class in AXE (Asp extreme edition) framework, and i used it but currently i don't understand how to use it well.

Edit: based on the correct answer of JSON.Stringify fails on Scripting.Dictionary objects Thread, i decided to make a custom function to process Recordsets.

Edit 2: Now i'm losing the value data when call JSON.stringify inside function JSONStringify(object).

when the Recordset is passed as value to JSONStringify everything is ok but when JSON.stringify is executed, the "value" parameter that must contain the recordset becomes undefined

What i'm expecting (example)

passing a Recordset with from a SQL query SELECT name, tel FROM users a see an output like this

[
    {"name":"Jonh Smith", "tel":"12345678"},
    {"name":"April Michelson", "tel":"77788802"},
    ...
]

passing a Dictionary and see something similar based in the elements declared in dictionary.

{
   "element1":"value1",
   "element2":"value2",
   "element3":"value3",
   "element4":"value4",
   "element5":"value5"
}

and if i like to support other type object i can do it expanding the function

Answer 1

This:

response.write(JSON.stringify(oRs))

Should read something like this:

Do Until oRS.EOF
  response.write(JSON.stringify(oRs("cve_gr") & ":" & oRs("descr"))
  oRS.MoveNext
Loop
