(VBScript) JSON: Array of Objects

Here we have a JSON object that contains an array, where each element in the array is a JSON object. This example demonstrates how to access the objects contained within an array.

{ 
  "employees":[
    {"firstName":"John", "lastName":"Doe"},
    {"firstName":"Anna", "lastName":"Smith"},
    {"firstName":"Peter","lastName":"Jones"}
  ]
}

Set fso = CreateObject("Scripting.FileSystemObject")

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.JsonObject")
set json = CreateObject("Chilkat.JsonObject")

' This is the above JSON with whitespace chars removed (SPACE, TAB, CR, and LF chars).
' The presence of whitespace chars for pretty-printing makes no difference to the Load
' method. 
jsonStr = "{""employees"":[{""firstName"":""John"", ""lastName"":""Doe""},{""firstName"":""Anna"", ""lastName"":""Smith""},{""firstName"":""Peter"",""lastName"":""Jones""}]}"

success = json.Load(jsonStr)
If (success <> 1) Then

' employees is a Chilkat.JsonArray
Set employees = json.ArrayOf("employees")
If (json.LastMethodSuccess = 0) Then
    outFile.WriteLine("employees member not found.")
    WScript.Quit
End If

' Iterate over each employee, getting the JSON object at each index.
numEmployees = employees.Size
i = 0
Do While i < numEmployees

    ' empObj is a Chilkat.JsonObject
