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

A :ref:`Variant<class_Variant>` containing the parsed JSON. Use :ref:`@GDScript.typeof<class_@GDScript_method_typeof>` or the ``is`` keyword to check if it is what you expect. For example, if the JSON source starts with curly braces (``{}``), a :ref:`Dictionary<class_Dictionary>` will be returned. If the JSON source starts with brackets (``[]``), an :ref:`Array<class_Array>` will be returned.
|
|
|
|
\ **Note:** 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 :ref:`float<class_float>` types.
|
|
|
|
\ **Note:** 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:
|
|
push_error("Unexpected results.")
