json.fields

json.fields() Function

• Introduced in version 1.3b49

Returns the fields (keys) for a JSON Object or the indexes for a JSON Array as a string list. The type of the value returned depends on the delimiter parameter.

• If the delimiter is not specified then a string list is returned with the default value of ',' is used.
• If the delimiter "json" then a JSON Array is returned.
• Otherwise a string list is returned with the delimiter passed in.

Note: Because JSON Objects are unordered, json.fields will not reflect the order they were set in.

Usage

[h: strList = json.fields(jobj)]
[h: strList = json.fields(jobj, delim)]
[h: jobj = json.fields(jobj, 'json')]

Example

  [h:a=json.fromStrProp("a=1;b=44;c=12")] [r:json.fields(a)]
  [h:a=json.fromList("a,1,g,4")][r:json.fields(a)]
  [h:a=json.fromStrProp("a=1;b=44;c=12")] [r:json.fields(a, "json")]
