javascript - 如何将数组附加到现有的 json javascript？

Question

我想创建一个像这样的 json 对象:

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

我想做这样的事情:

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”部分。我该如何实现？

Answer 1

您收到此错误是因为您正在将对象创建为数组。您必须创建一个对象来添加属性:

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

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