如何將數組追加到現有的json javascript？

Question

我想創建這樣一個JSON對象：

{ 
    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}); 

但我無法創建「電影」的一部分。我該如何做到這一點？

Answer 1

由於您將對象創建爲數組，因此出現此錯誤。你必須創建一個對象添加屬性：

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

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

Answer 2

你不能混用數據類型（按僅適用於數組和使用對象的屬性），嘗試這樣的事情：

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

你們這工作

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>
