Convert JS object to JSON string

Question

If I defined an object in JS with:

var j={\"name\":\"binchen\"};

How can I convert the object to JSON? The output string should be:

Answer 1

Use the stringify function

var j = {
"name":"binchen"
};

var j_json = JSON.stringify(j);

console.log("j in json object format :", j_json);

Happy coding!!!

Answer 2

Woking... Easy to use

$("form").submit(function(evt){
  evt.preventDefault();
  var formData = $("form").serializeArray(); // Create array of object
  var jsonConvert = JSON.stringify(formData);  // Convert to json
});

Thanks

Answer 3

Very easy to use method, but don't use it in release (because of possible compatibility problems).

Great for testing on your side.

Object.prototype.toSource()

//Usage:
obj.toSource();

Answer 4

The most popular way is below:

var obj = {name: "Martin", age: 30, country: "United States"};   
// Converting JS object to JSON string
var json = JSON.stringify(obj);
console.log(json);

Answer 5

Use the JSON.stringify() method:

const stringified = JSON.stringify({})  // pass object you want to convert in string format

Answer 6

With JSON.stringify() found in json2.js or native in most modern browsers.

   JSON.stringify(value, replacer, space)
        value       any JavaScript value, usually an object or array.

       replacer    an optional parameter that determines how object
                    values are stringified for objects. It can be a
                    function or an array of strings.

       space       an optional parameter that specifies the indentation
                    of nested structures. If it is omitted, the text will
                    be packed without extra whitespace. If it is a number,
                    it will specify the number of spaces to indent at each
                    level. If it is a string (such as '\t' or ' '),
                    it contains the characters used to indent at each level.

       This method produces a JSON text from a JavaScript value.
