JSONGetKeys

Syntax

JSONGetKeys <json-var>

Description

Return a list of the member names contained in a JSON object.

Parameters

<json-var>

The JSON object whose member names are desired.

Remarks

JSON (JavaScript Object Notation) is a lightweight data format based on the object notation of the JavaScript language. It does not require JavaScript to read or write; it is easy to parse by any language and libraries and tools exist in many languages to handle JSON.

Here is the entire list of PhantomScript JSON statements: ListAsJSONArray, JSONAddArray, JSONAddBoolean, JSONAddNull, JSONAddNumber, JSONAddObject, JSONAddString, JSONArrayAsList, JSONGetKeys, JSONGetType, JSONGetValue, JSONDelete.

Example

Local jsonObj1 

JSONAddString jsonObj1 "string1" "a string value" 
JSONAddNumber jsonObj1 "a-number" 42 
JSONAddBoolean jsonObj1 "a-boolean" (1 = 1) 

Log "keys = " & JSONGetKeys jsonObj1 

jsonObj = JSONDelete jsonObj1 "a-number" 

Log "keys = " & JSONGetKeys jsonObj1 

The above script fragment logs the following:

keys = string1,a-number,a-boolean
keys = string1,a-boolean
