I’ve been developing around CFAJAX automatically instantiating any coldfusion struct in Javascript as an array of KEY:VALUE pairs. I fell victim to several traps in CFAJAX when there were ever a KEY:VALUE pair with the VALUE being an empty string.

The more I dug around the cfajax code the more I figured it would be best to take the coldfusion structure and convert it to JSON instead of trying to rebuild it into this odd array of KEY:VALUE pairs.

Just a proof of concept - Fetch the nice “CFJSON” CFC code from http://www.epiphantastic.com/cfjson/ (authored by Jehiah Czebotar). I use the following code in the Structure section of the parseResult cffunction in cfajax.cfm:

Download this code: cfajax_json

This outputs :

_6497_1171934480366 = {"FIRST_NAME":"ASD",LAST_NAME":"ASD","HEIGHT":72,"_BILLING"
:{"CITY":"Mammoth Lakes","STATE":"CA "}};
DWREngine._handleResponse('6497_1171934480366', _6497_1171934480366, true, true, true);
/* EOF CFAJAX */

.. instead of :
