I have a json as below
var object = {200x200: "url1", 400x400: "url2", 800x800: "url3"};
I stringified the object and tried to acccess "200x200". But its throwing
undefined
object = JSON.stringify(object);
//object = {"200x200": "url1", "400x400": "url2", "800x800": "url3"};
I tried to access like this
object['200x200'] // got undefined
Any other way to access the url1 from this object ?
Because you json object is wrong format:
Wrap your keys in quotes, like this: https://codepen.io/creativedev/pen/LrBOmG
var object = {'200x200': "url1",'400x400': "url2", '800x800': "url3"};
Then check:
console.log(object['200x200']);
you will get output
you should change you object to
var object = {'200x200': "url1", '400x400': "url2", '800x800': "url3"};
object['200x200'] // 'url1'
Once you stringify it, it's a string. You have to parse it back into an object.
var newObject = JSON.parse(object);
console.log(object[200x200];
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse
You can parse it:
object = JSON.parse(object);
then access the key:
let url1 = object['200x200']
No idea why you would stringify it in the first place though!
let jsonObject = JSON.stringify(object);
// instead of:
let url1 = JSON.parse(JSON.stringify(object))['200x200']
