Working With JSON In ColdFusion 8

ColdFusion 8 adds support for JSON in several ways

Jun. 4, 2007 10:45 PM

There have been some comments on other entries here regarding JSON. JSON is a data interchange format, and is primarily used as a way to package data for use with Ajax development.

ColdFusion 8 (aka Scorpio) adds support for JSON in several ways:

For starters, two new functions named SerializeJSON() and DeserializeJSON() make it easy to convert data to and from JSON. Simple variables (numbers and strings), dates, arrays, structures, and even queries can be converted back and forth. ColdFusion queries get converted into JSON objects with two entries, COLUMNS contains a list of columns, and DATA is an array of arrays containing the actual data.
A supporting IsJSON() function does exactly what its name suggests.
In addition, CFC methods can now be instructed to return data serialized as JSON by specifying returnformat="json". This is perfect for Ajax controls that invoke CFC methods to retrieve data.

About Ben Forta
Ben Forta is Adobe's Senior Technical Evangelist. In that capacity he spends a considerable amount of time talking and writing about Adobe products (with an emphasis on ColdFusion and Flex), and providing feedback to help shape the future direction of the products. By the way, if you are not yet a ColdFusion user, you should be. It is an incredible product, and is truly deserving of all the praise it has been receiving. In a prior life he was a ColdFusion customer (he wrote one of the first large high visibility web sites using the product) and was so impressed he ended up working for the company that created it (Allaire). Ben is also the author of books on ColdFusion, SQL, Windows 2000, JSP, WAP, Regular Expressions, and more. Before joining Adobe (well, Allaire actually, and then Macromedia and Allaire merged, and then Adobe bought Macromedia) he helped found a company called Car.com which provides automotive services (buy a car, sell a car, etc) over the Web. Car.com (including Stoneage) is one of the largest automotive web sites out there, was written entirely in ColdFusion, and is now owned by Auto-By-Tel.
