的JavaScript建立动态对象

Question

我有一个名为onversation变种包含此：

{ 
    "conversationId": "adbabc54-3308-436d-a48b-932f4010d3c6", 
    "participantId": "415651e6-f0a5-4203-8019-4f88c3ed9cd5" 
} 

我也有一个名为person包含此对象：

{ 
    firstname: "fred", 
    surname: "smith", 
    age: "21", 
    gender: "male" 
} 

我想什么是有一个名为result的组合对象，看起来像这样

result { 
    conversation { 
     conversationId : adbabc54-3308-436d-a48b-932f4010d3c6, 
     participantId : 415651e6-f0a5-4203-8019-4f88c3ed9cd5 
    }, 
    person { 
     firstname: "fred", 
     surname: "smith", 
     age: "21", 
     gender: "male" 
    } 
} 

我该如何动态地执行此操作，从而使用var'conversation'的名称和对象'person'的名称来构建结果对象？

此外，对话或人的长度可以是任意长度。如果可能的话 纯JavaScript，但可以使用下划线等

如果我正确理解你的问题，你可以使用它在大多数浏览器都支持（可能是所有的人，除了IE11）对象的速记符号，简化您的解决方案更：

var conversation = 
 
{ 
 
    conversationId : 'adbabc54-3308-436d-a48b-932f4010d3c6', 
 
    participantId : '415651e6-f0a5-4203-8019-4f88c3ed9cd5' 
 
}; 
 
var person = 
 
{ 
 
    firstname: "fred", 
 
    surname: "smith", 
 
    age: "21", 
 
    gender: "male" 
 
}; 
 

 
var result = { conversation, person } 
 

 
console.log(result)

编辑： 如果仅仅变量名的变化，这是属性名称保持不变或有某种独特的键，你可以使用一个对对象的关键环。

例如：

var someConversationVariableName = 
 
{ 
 
    conversationId : 'adbabc54-3308-436d-a48b-932f4010d3c6', 
 
    participantId : '415651e6-f0a5-4203-8019-4f88c3ed9cd5' 
 
}; 
 
var somePersonVariableName = 
 
{ 
 
    firstname: "fred", 
 
    surname: "smith", 
 
    age: "21", 
 
    gender: "male" 
 
}; 
 

 
var result = { someConversationVariableName, somePersonVariableName } 
 

 
for (key in result) { 
 
    if(result[key]['conversationId']) { 
 
    console.log(`Found conversation object. It's name is: ${key}`); 
 
    } 
 
    else if(result[key]['firstname']) { 
 
    console.log(`Found person object. It's name is: ${key}`); 
 
    } 
 
} 
 

Answer 2

试试吧

var result = { 
'conversation': conversation, 
'person': person 
} 

动态

var result = {} 

result['person'] = person 

或

resilt.person = person 

Answer 3

如果需要推迟添加对象，你也可以采取这种方式：

var conversation = 
{ 
    conversationId : 'adbabc54-3308-436d-a48b-932f4010d3c6', 
    participantId : '415651e6-f0a5-4203-8019-4f88c3ed9cd5' 
}; 
var person = 
{ 
    firstname: "fred", 
    surname: "smith", 
    age: "21", 
    gender: "male" 
}; 

var result = {}; 

result['conversation'] = conversation; 
result['person'] = person; 

console.log(result); 

Answer 4

这必须工作： -

var conversation = 
{ 
    "conversationId": "adbabc54-3308-436d-a48b-932f4010d3c6", 
    "participantId": "415651e6-f0a5-4203-8019-4f88c3ed9cd5" 
} 

var person= 
{ 
    firstname: "fred", 
    surname: "smith", 
    age: "21", 
    gender: "male" 
} 

var result = { 
'conversation': conversation, 
'person': person 
}
