使用 JSON 解析时保留引号

Question

I've been unable to phrase this question in a way when searching which yields any results, so forgive me if there is an obvious place this has been asked.

I'd like all quotation marks to remain in my JSON when converting from a string.

My UI has a text field (string) which a user will type some JSON which will look something like this:

{ "example": "example" }

I'd like all the quotation marks to remain in my JSON object. However, when I run JSON.parse() on the above string, I get the following:

{ example: "example" }

How can I keep the quotation from being removed?

Answer 1

A javascript object, which is what JSON.parse() returns, is not json. You don't need the quotes in an object (unless there are special characters in the property name) and can access that property with or without quotes in your code

const myObj = { example: "example" };

Both of the following are valid

console.log(myObject.example)
console.log(myObject["example"])

When you JSON.stringify() this again it will have valid quotes in the json string and be:

{ "example": "example" }

Answer 2

JSON.parse() returns a javascript object , so the results you are getting are correct.

Your backend needs a JSON string , not a javascript object, so you need to JSON.stringify() your javascript object to obtain the JSON string that your backend requires.

let userinput = '{ "example": "example" }';
let userobject = JSON.parse(userinput);
let resultjson = JSON.stringify(userobject);

console.log(userinput);
console.log(userobject);
console.log(resultjson);

produces

{ "example": "example" }
{ example: 'example' }
{"example":"example"}
