Javascript 将JSON对象合并到数组中

javascript json node.js

Javascript 将JSON对象合并到数组中,javascript,json,node.js,concat,Javascript,Json,Node.js,Concat,如果第一个对象是： { "total": "2" } 第二： [ "player1": { "score": "100", "ping": "50" }, "player2": { "score": "100", "ping": "50" } ] 如果我希望最终结果如下所示： { "total": "2", { "playe

如果第一个对象是：

{
     "total": "2"
}

第二：

[
     "player1": {
          "score": "100",
          "ping": "50"
     },
     "player2": {
          "score": "100",
          "ping": "50"
     }
]

如果我希望最终结果如下所示：

{
     "total": "2",
     {
          "player1": {
               "score": "100",
               "ping": "50"
          },
          "player2": {
               "score": "100",
               "ping": "50"
          }
     }
}

我正在尝试用JavaScript来实现它

更新

最终结果不是有效数组。这个怎么样

{
     [
          "player1": {
               "score": "100",
               "ping": "50"
          },
          "player2": {
               "score": "100",
               "ping": "50"
          }
     ]
}

您的json无效。如果你想要一些有效的东西，你需要做如下的事情

{
  "total": "2",
  "players": [
     "player1": {
          "score": "100",
          "ping": "50"
     },
     "player2": {
          "score": "100",
          "ping": "50"
     }
  ]
}

您的json无效。如果你想要一些有效的东西，你需要做如下的事情

{
  "total": "2",
  "players": [
     "player1": {
          "score": "100",
          "ping": "50"
     },
     "player2": {
          "score": "100",
          "ping": "50"
     }
  ]
}

您的示例不是正确的JSON对象，您应该这样做

var x = { "total": "2" }
x.players = playerArray

您的示例不是正确的JSON对象，您应该这样做

var x = { "total": "2" }
x.players = playerArray

正如我在评论中所说，
您试图附加一个无效数组，结果得到一个无效JSON树

要验证预期的JSON，可以在此处进行测试：

怎么了1：

[ "player1" : { "score": "100", "ping": "50"} ] // Array ??
            ^ invalid delimiter (should be ,)

预期结果中的错误2：

 {
     "property" : "value" ,
     "total" : "2" ,
          { "player1" : { "score": "100", "ping": "50" }
     ^^^^^ where's the property here???  
 }

你能做什么：

var myObject = {"total":"2"};    
var players = {
         "player1": {
              "score": "100",
              "ping": "50"
         },
         "player2": {
              "score": "100",
              "ping": "50"
         }
};

myObject.players = players;

console.log( myObject );

这将导致：

[object Object] {
  players: [object Object] {
    player1: [object Object] { ... },
    player2: [object Object] { ... }
  },
  total: "2"
}

对象文字需要逗号分隔的

属性：值

对模型

{
   "property1" : val,
   "property2" : [],
   "property3" : "String",
   "property4" : {}
}

以上是一个有效的JSON原因，这意味着您的属性名用双引号括起来

数组（如您的问题所示）不能用

：

分隔，而是用

，

myArr = ["string", {}, value]; // is a valid Array.

对象：

myArr = ["string", {"objectProperty":"val"}, value];

现在要从数组中获取键值：

myArr[0] // "string"
myArr[1] // {object Object}
myArr[1].objectProperty // "val" // get Object property value

从上面可以看出，数组是存储在编号键中的值（基于0），而对象是属性-值对。它们的共同点是逗号（，）分隔符。
