javascript错误SyntaxError：缺少：属性ID后

如何解决javascript错误SyntaxError：缺少：属性ID后

尝试在对象数组内创建字符串数组，并得到一条错误消息，提示SyntaxError：missing：JavaScript以下代码的属性ID之后

let movies = [
  {
  movie title: 'Avengers: Age of Ultron',release year: '2015',rating:'7.3',"genres"=[0:"Action",1:"Adventure",2:"Sci-Fi"]
},{
  movie title: 'The Dark Knight',release year:'2008',rating:'9.0',genres:["Action","Crime","Drama"]
},{
  movie title: 'Forrest Gump',release year:'1994',rating:'8.8',genres:["Drama","Romance"]
},{
  movie title: 'Inception',release year:'2010',"Adventure","Sci-Fi"]
},{
  movie title: 'The Matrix',release year:'1999',rating:'8.7',{
  movie title: 'Border',release year:'1997',rating:'7.9',"Drama","History"]
}
  ];

解决方法

您的代码中有两个错误。

1. 如果JSON对象键包含''，则应输入“。
2. 您不需要为JSON对象值编写索引。

这是更新的代码。

let movies = [
    {
    "movie title": 'Avengers: Age of Ultron',"release year": '2015',rating:'7.3',genres:["Action","Adventure","Sci-Fi"]
  },{
    "movie title": 'The Dark Knight',"release year":'2008',rating:'9.0',"Crime","Drama"]
  },{
    "movie title": 'Forrest Gump',"release year":'1994',rating:'8.8',genres:["Drama","Romance"]
  },{
    "movie title": 'Inception',"release year":'2010',{
    "movie title": 'The Matrix',"release year":'1999',rating:'8.7',{
    "movie title": 'Border',"release year":'1997',rating:'7.9',"Drama","History"]
  }
    ];
