如何将数组追加到现有的json javascript？

Question

我想创建这样一个JSON对象：

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

我想要做的事，如：

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

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

但我无法创建“电影”的一部分。我该如何做到这一点？

Answer 1

由于您将对象创建为数组，因此出现此错误。你必须创建一个对象添加属性：

var myobj = {name: "Julia", birthdate: "xxxx"}; 

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

Answer 2

你不能混用数据类型（按仅适用于数组和使用对象的属性），尝试这样的事情：

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

你们这工作

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>
