Returns the JSON type of a value associated with a key in a JSON container.
jsValueType ( container-handle , key-name, [, key-delimiter] )
(s) container-handle: extender JSON handle.
(s) key-name: name of an existing key including the full JSON path to the key.
(s) key-delimiter: [optional] single character used between key names in any path included in the key-name parameter (defaults to a dot character(".")).
(i) integer indicating the JSON type of a value (see table below.)
This function is almost identical to jsValueGet except that it retrieves the JSON type of value of a key/value pair contained within the passed in JSON object, one of its child objects, or array contained within the object or sub object.
Container-Handle
The unique identifier returned from a call to the jsParse, jsObjNew, jsValueGet functions, or by accessing WIL map element returned by the jsConMap function. The key-name with path must be a path to a key in this object or one of its child containers.
Key-Name
The key name of a simple key/value pair, an array key name with bracketed index, or an empty bracket with bracketed index for an anonymous array. The name must include JSON path information when the pair exists in a child container and a bracketed index number when targeting an element of an array. See the About JSON Paths topic for detailed description of JSON paths.
Important:
JSON key names are case sensitive, so make sure the key-name is spelled correctly and matches the case of the key stored in the JSON data.
A key-name and any path container names must always be surrounded by square brackets when the name contains embedded square brackets or the current key-name delimiter.
Key-Delimiter
An optional parameter that must be a single character used between key specifications in the JSON path. The default value is a dot ("."). The space(' '), backslash('\'), single-quote("'"), double-quote('"'), dollar-sign("$"), left-bracket("["), right-bracket("]") and grave-accent("`") cannot be used as delimiters.
