Tipo de erro

+ +

{{jsxref("SyntaxError")}}

+ +

O que ocorreu de errado?

+ +

{{jsxref("JSON.parse()")}} converte uma string para JSON. A string precisa ser um JSON válido e retornará esse erro caso a sintaxe esteja errada.

+ +

Exemplos

+ +

JSON.parse() não permite vírgulas à direita

+ +

As duas linhas retornarão um SyntaxError:

+ +
JSON.parse('[1, 2, 3, 4,]');
+JSON.parse('{"foo": 1,}');
+// SyntaxError JSON.parse: unexpected character
+// at line 1 column 14 of the JSON data
+
+ +

Retire as virgulas sobrando para converter o JSON corretamente:

+ +
JSON.parse('[1, 2, 3, 4]');
+JSON.parse('{"foo": 1}');
+ +

Propriedades precisão ser escritas com aspas duplas

+ +

Você não pode usar aspas simples em propriedades, exemplo: 'foo'.

+ +
JSON.parse("{'foo': 1}");
+// SyntaxError: JSON.parse: expected property name or '}'
+// at line 1 column 2 of the JSON data
+ +

Em vez disso use "foo":

+ +
JSON.parse('{"foo": 1}');
+ +

Zeros à esquerda e pontos decimais

+ +

Você não pode usar zeros à esquerda, como 01, e pontos decimais precisam ser seguidos de pelo menos um digito.

+ +
JSON.parse('{"foo": 01}');
+// SyntaxError: JSON.parse: expected ',' or '}' after property value
+// in object at line 1 column 2 of the JSON data
+
+JSON.parse('{"foo": 1.}');
+// SyntaxError: JSON.parse: unterminated fractional number
+// at line 1 column 2 of the JSON data
+
+ +

Em vez disso, use o 1 sem o zero, e pelo menos um digito após um ponto decimal:

+ +
JSON.parse('{"foo": 1}');
+JSON.parse('{"foo": 1.0}');
+
+ +
