How to append array to existing json javascript?

Question

I want to create a json object like:

{ name: "Julia" birthdate: "xxxx" movies: [{title: "movie1", rating: 5}, {title: "movie2", rating 3}}] } 

I want to do something like:

var myobj = []; myobj.push({name: "Julia", birthdate: "xxxx"}); myobj.movies = []; myobj.movies.push({title: "movie1", rating: 5}); myobj.movies.push({title: "movie2", rating: 3}); 

But I am unable to create that "movies" part. How do I accomplish this?

Answer 1

You are getting this error because you are creating the object as an array. You have to create as an object to add properties:

var myobj = {name: "Julia", birthdate: "xxxx"}; myobj.movies = []; myobj.movies.push({title: "movie1", rating: 5}); myobj.movies.push({title: "movie2", rating: 3}); 

Answer 2

You cannot mix datatypes(push works only on Arrays and attributes with objects), try something like this:

var myobj = {}; myobj.persons = []; myobj.persons.push({name: "Julia", birthdate: "xxxx"}); myobj.movies = []; myobj.movies.push({title: "movie1", rating: 5}); myobj.movies.push({title: "movie2", rating: 3}); 

Answer 3

ye this works

var myobj = []; myobj.push({name: "Julia", birthdate: "xxxx"});

myobj.push({movies: []}); myobj.movies = []; myobj.movies.push({title: "movie1", rating: 5}); myobj.movies.push({title: "movie2", rating: 3}); console.log(myobj);</code>
