(Visual Basic 6.0) JSON: Nested ArrayHere we have a JSON object that contains nested arrays. This example demonstrates how to access the contents of the nested arrays. { "numbers" : [ ["even", 2, 4, 6, 8], ["prime", 2, 3, 5, 7, 11, 13] ] }
Dim json As New ChilkatJsonObject ' 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. Dim jsonStr As String jsonStr = "{ ""numbers"" : [ [""even"", 2, 4, 6, 8], [""prime"", 2, 3, 5, 7, 11, 13] ] }" Dim success As Long success = json.Load(jsonStr) If (success <> 1) Then Debug.Print json.LastErrorText Exit Sub End If ' Get the value of the "numbers" object, which is an array that contains JSON arrays. Dim outerArray As ChilkatJsonArray Set outerArray = json.ArrayOf("numbers") If (json.LastMethodSuccess = 0) Then Debug.Print "numbers array not found." Exit Sub End If Dim numArrays As Long numArrays = outerArray.Size Dim i As Long For i = 0 To numArrays - 1 Dim innerArray As ChilkatJsonArray Set innerArray = outerArray.ArrayAt(i) ' The first item in the innerArray is a string Debug.Print innerArray.StringAt(0) & ":" Dim numInnerItems As Long numInnerItems = innerArray.Size Dim j As Long For j = 1 To numInnerItems - 1 Debug.Print " " & innerArray.IntAt(j) Next Next |
