(VBScript) Understanding JSON Array vs JSON ObjectThis example explains the difference between a JSON Array and a JSON Object. A JSON Array begins with "[" and ends with "]", whereas a JSON Object begins with "{" and ends with "}". Elements contained in a JSON array are accessed by index, whereas elements in a JSON object are typically accessed by name (but can also be accessed by index).
Dim fso, outFile Set fso = CreateObject("Scripting.FileSystemObject") Set outFile = fso.CreateTextFile("output.txt", True) ' A JSON array should be loaded into a Chilkat JSON array, ' whereas a JSON object should be loaded into a Chilkat JSON object. ' A JSON array may contain objects, and a JSON object may contains arrays, but ' it is the top-level (outermost) element that defines whether the JSON ' document is an array or an object. ' An array begins and ends with "[" ... "]" ' An object begins and ends with "{" ... "}" ' For example, an array containing 2 objects: strJsonArray = "[ { ""name"": ""Bill"" }, { ""name"": ""Ted"" } ]" ' Load it into a JSON array. set jsonA = CreateObject("Chilkat_9_5_0.JsonArray") success = jsonA.Load(strJsonArray) outFile.WriteLine("number of array elements: " & jsonA.Size) ' This is an object containing an array: strJsonObj = "{ ""characters"": [ ""Bill"", ""Ted"" ] }" ' Load it into a JSON object. set jsonO = CreateObject("Chilkat_9_5_0.JsonObject") success = jsonO.Load(strJsonObj) outFile.WriteLine("number of object members: " & jsonO.Size) outFile.Close |
