Question

在Node.js中，我想转换为将嵌套对象扩展为数组，详情如下：

 {
"topic":"myTopic",
"content":{
    "name": {
        "tom1" : {
            "value": "String",
        },
        "tom2" : {
            "value": "String",
        },
        "tom3" : {
            "value": "String",
        }
    }
}
}

转换并扩展为以下格式

[{
"topic":"myTopic",
"content":{
    "name": {
        "tom1" : {
            "value": "String",
        }
    }
}
},

{
"topic":"myTopic",
"content":{
    "name": {           
        "tom2" : {
            "value": "String",
        }
    }
 }
 },
{
"topic":"myTopic",
"content":{
    "name": {           
        "tom3" : {
            "value": "String",
        }
    }
}
}]

Answer 1

您可以尝试以下内容：

var result = []; // contains the array you're looking for
var test = { "topic":"myTopic", "content":{ "name": { "tom1" : { "value": "String", }, "tom2" : { "value": "String", }, "tom3" : { "value": "String", } } } };
Object.keys(test.content.name).map((e,i) => { 
    let temp = {}; 
    temp[e] = test.content.name[e]; 
    result.push({topic: test.topic, content: { name: temp }}); 
});

这对你有帮助吗？

x = { "topic":"myTopic", "content":{ "name": { "tom1" : { "value": "String", }, "tom2" : { "value": "String", }, "tom3" : { "value": "String", } } } };

console.log(Object.keys(x.content.name).map((n) => { 
let y = JSON.parse(JSON.stringify(x)); 
y.content.name = {}; 
y.content.name[n] = x.content.name[n]; 
return y; 
}))

您可以使用map和一些Object方法：

function splitObject(obj) {
    return Object.keys(obj.content.name).map( key => Object.assign({}, {
        content: { name: { [key]: obj.content.name[key] } }
    }) );
}

const obj = { 
    topic: "myTopic", 
    content: { 
        name: { 
            tom1: { 
                value: "String", 
            }, 
            tom2: { 
                value: "String", 
            }, 
            tom3: { 
                value: "String", 
            } 
        } 
    } 
};

const result = splitObject(obj);

console.log(result);
