(Classic ASP) JSON: Nested ObjectsHere we have a JSON object that contains nested JSON objects. This example demonstrates how to access the contents of the nested objects. { "name": "donut", "image": { "fname": "donut.jpg", "w": 200, "h": 200 }, "thumbnail": { "fname": "donutThumb.jpg", "w": 32, "h": 32 } } Note: This example requires Chilkat v11.0.0 or greater.
