How do I stringify an array of objects?

Question

I have created an array of objects that needs to be stored and kept for another page.

The array of objects is similar to this:

var cheese_array = [
          


        

Answer 1

You're missing a , in your 3rd object, after age:

var cheese_array = [
  {
    name: "Chedder",
    age: "34",
    smelly: true
  },
  {
    name: "Brie",
    age: "4",
    smelly: false
  },
  {
    name: "Blue Stilton",
    age: "13",
    smelly: true
  }
 ];

var jsonObj = JSON.stringify(cheese_array);

This will now work and display correctly.

Answer 2

Your object misses a comma as shown below:

name: "Blue Stilton",
    age: "13"//comma is missing here
    smelly: true

JSON.stringify works fine as shown below.

var cheese_array = [
  {
    name: "Chedder",
    age: "34",
    smelly: true
  },
  {
    name: "Brie",
    age: "4",
    smelly: false
  },
  {
    name: "Blue Stilton",
    age: "13",
    smelly: true
  }
 ];
console.log(JSON.stringify(cheese_array))

However I am not sure how you get a log [object Object], [object Object], [object Object] I am presuming you are console logging something else please check that in your code.

Answer 3

Update JSON with ,(Comma) in

 name: "Blue Stilton",
    age: "13",
    smelly: true

var cheese_array = [
  {
    name: "Chedder",
    age: "34",
    smelly: true
  },
  {
    name: "Brie",
    age: "4",
    smelly: false
  },
  {
    name: "Blue Stilton",
    age: "13",
    smelly: true
  }
 ];

var details = JSON.stringify(cheese_array);
alert(details);
