javascript - Convert a non-standard JS string into a standard json object

Question

I have the following js string

var aaa='{a:1,b:2,c:3}';

How to quickly convert aaa into a standard Json object like {'a':1,'b':2,'c':3}?

Answer 1

You have a misunderstanding of the standard JSON object. The attributes of standard JSON are enclosed in double quotes. Neither single quotes nor single quotes will work.

JSON.parse(str) The str parameter received here must be a string that conforms to the JSON format. If it does not conform to the JSON format, an error will be reported.

So first add double quotes to the properties of the object.

If you don’t want to use eval, you can use this method,

var aaa="{a:1, b:2, c:3}";
function toJSONStr(str) {
  return str.replace(/([$\w]+)\s*:/g, function(_, ){return '"'++'":'});
}
function toJSON(str) {
  return JSON.parse(str);
}
toJSON(toJSONStr(aaa));

SyntaxError: JSON.parse: bad parsing

Answer 2

JSON.parse(aaa);

JSON.stringify: json =》string
JSON.parse：string=》json

Answer 3

var result = eval('('+aaa+')');
