JSON.parse unexpected character error
JavascriptJsonJavascript Problem Overview
I get this error:
> JSON.parse: unexpected character
when I run this statement in firebug:
JSON.parse({"balance":0,"count":0,"time":1323973673061,"firstname":"howard","userId":5383,"localid":1,"freeExpiration":0,"status":false});
Why is it so? The JSON string seems correct to me and I also tested it using JSHint. The passed object in the above case is a server response with content type set to application/json
Javascript Solutions
Solution 1 - Javascript
You're not parsing a string, you're parsing an already-parsed object :)
var obj1 = JSON.parse('{"creditBalance":0,...,"starStatus":false}');
// ^ ^
// if you want to parse, the input should be a string
var obj2 = {"creditBalance":0,...,"starStatus":false};
// or just use it directly.
Solution 2 - Javascript
You can make sure that the object in question is stringified before passing it to parse function by simply using JSON.stringify()
.
Updated your line below,
JSON.parse(JSON.stringify({"balance":0,"count":0,"time":1323973673061,"firstname":"howard","userId":5383,"localid":1,"freeExpiration":0,"status":false}));
or if you have JSON stored in some variable:
JSON.parse(JSON.stringify(yourJSONobject));
Solution 3 - Javascript
Not true for the OP, but this error can be caused by using single quotation marks ('
) instead of double ("
) for strings.
The JSON spec requires double quotation marks for strings.
E.g:
JSON.parse(`{"myparam": 'myString'}`)
gives the error, whereas
JSON.parse(`{"myparam": "myString"}`)
does not. Note the quotation marks around myString
.
