为什么 JSON.parse 不适用于此字符串？

Question

I can't parse the following string:

 try { var data_obj = JSON.parse("{'raw': -243666272256, 'format': '-24.67BB', 'longFormat': '-243,666,272M'}") } catch (e) { console.error(e); } cnsole.log(data_obj.raw)

Answer 1

JSON standard does not allow single quotation when you wrap your property and do not parse it. Instead, It expects double quotation. Please check the below example:

var data_obj = JSON.parse('{"raw":-243666272256,"format":"-24.67BB","longFormat":"-243,666,272M"}');
        console.log(data_obj, 'data');
        console.log(data_obj.raw);
