Question

I have this variable which is json-like string, error appear while parse to a object

"SyntaxError: JSON.parse: expected ',' or '}' after property value in object"

Code:

var obj = JSON.parse('{"data":[{"from":"{\"category\":\"Bank/financial institution\"}"}],"statusCode":200}');

Seems the function not available for nested "{\"category\":\"Bank/financial institution\"}", replace with simple text (e.g. “123”) would be fine, is there any way to handle such cases?
Thanks.

Answer 1

Your string is indeed malformed.

You either want:

var obj = JSON.parse('{"data":[{"from":{"category":"Bank/financial institution"}}],"statusCode":200}');

…(e.g., without quotes around the value of from and without backslashes) which when deserialized results in an object with a property called data which is an array, which has as its first entry an object with a property called from which is an object: Live Example | Source

or

var obj = JSON.parse('{"data":[{"from":"{\\"category\\":\\"Bank/financial institution\\"}"}],"statusCode":200}');

…(e.g., keeping the quotes around the value for from and making sure the backslashes appear in the JSON, which means escaping them) which is the same until you get to from, which is a string: Live Example | Source
