Thanks a million for helping and information,
I found the issues now,
cffunction returns JSON data type depends on the data.
for example, the code are "0D", "00" and "ZD" in the same field.
cffunction sends out sometimes consider 00 and 0D are numbers without double quote, but ZD consider a string so it includes double quote.
Are there any way to force "0D" and "00" to be a string in JSON data out from cffunction?
Your help and information is great appreciated,
Regards,
Iccsi,
