I'm trying to parse JSON with jQuery I get from a remote server through AJAX. The JSON data is like: {identifier:"ID", label:"LABEL"} but unable to. Apparently, the field identifier and label has no double quotes. It works when tested on my local test site with double quotes.
Can it be made to work without quotes with jQuery? I have searched around and have found no solutions.
Any input is appreciated. Thanks.
Yeah, it's not valid JSON, blahblahblah... like everyone cares if it's valid or not.
At least I don't care, I just want to parse it, so I wrote jsonlite.
with Jsonlite, you can do this:
var s = '{name: jsonlite, birthday: {year: 2013, month: 7, day: 7}, isGreat: true}';
var obj = jsonlite.parse(s);
Which produces exactly the same result as the code below:
var s = '{"name": "jsonlite", "birthday": {"year": 2013, "month": 7, "day": 7}, "isGreat": true}';
var obj = $.parseJSON(s);
You can't. JSON specification says this:
A string is a sequence of zero or more Unicode characters, wrapped in double quotes, using backslash escapes. A character is represented as a single character string. A string is very much like a C or Java string.
Meaning string as the label you mention.

Using a regular expression the invalid JSON can be made valid JSON. In example below the sFixed will be valid JSON, which can be parsed: .
let s = '{identifier:"ID", label:"LABEL"}',
sFixed = s.replace(/(['"])?([a-zA-Z0-9_][a-zA-Z0-9_\s]*[a-zA-Z0-9_])(['"])?:/g, '"$2": '), //'{"identifier":"ID", "label":"LABEL"}'
obj = JSON.parse(sFixed);
