Description

-----------
|
|
|
|
Returned by :ref:`JSON.parse<class_JSON_method_parse>`, ``JSONParseResult`` contains decoded JSON or error information if JSON source not successfully parsed. You can check if JSON source was successfully parsed with ``if json_result.error == OK``.

A :ref:`Variant<class_Variant>` containing the parsed JSON. Use typeof() to check if it is what you expect. For example, if JSON source starts with curly braces (``{}``) a :ref:`Dictionary<class_Dictionary>` will be returned, if JSON source starts with braces (``[]``) an :ref:`Array<class_Array>` will be returned.
|
|
|
|
*Be aware that the JSON specification does not define integer or float types, but only a number type. Therefore, parsing a JSON text will convert all numerical values to float types.*
|
|
|
|
Note that JSON objects do not preserve key order like Godot dictionaries, thus you should not rely on keys being in a certain order if a dictionary is constructed from JSON. In contrast, JSON arrays retain the order of their elements:*
|
|
|
|
::
|
|
|
|
var p = JSON.parse('["hello", "world", "!"]')
|
|
if typeof(p.result) == TYPE_ARRAY:
|
|
print(p.result[0]) # prints 'hello'
|
|
else:
|
|
print("unexpected results")
