【问题描述】：

有没有办法使用 javascript 实现这种 json 转换？

输入

"server":"S1",
"timestamp":"123456",
"data":[
        "device":"D1", "price":"50",
        "device":"D2", "price":"60",
        "device":"D3", "price":"70"
     ]

输出

"data":[
     "server":"S1", "timestamp":"123456", "device":"D1", "price":"50",
     "server":"S1", "timestamp":"123456", "device":"D2", "price":"60",
     "server":"S1", "timestamp":"123456", "device":"D3", "price":"70"
]

【问题讨论】：

到目前为止你做了什么？

【参考方案1】：

假设您的输入对象是

var input = 
"server":"S1",
"timestamp":"123456",
"data":[
    "device":"D1", "price":"50",
    "device":"D2", "price":"60",
    "device":"D3", "price":"70"
 ]
  

您可以转换为预期的输出，

let output = 
data:[]
 

input.data.forEach(transformfunction);

function transformfunction(value,index,array)

  output.data.push(
             
             "server":input.server,
             "timestamp":input.timestamp,
              "device":array[index].device,
              "price":array[index].price
          
      );

  

  console.log(JSON.stringify(output));

我希望它有所帮助。

这个答案适用于我没有使用任何 ES6 功能的所有浏览器！

【参考方案2】：

试试这个：

const data  = 
"server":"S1",
"timestamp":"123456",
"data":[
        "device":"D1", "price":"50",
        "device":"D2", "price":"60",
        "device":"D3", "price":"70"
     ]



result = data: data.data.map(res=>(...res, ...'timestamp': data.timestamp, 'server': data.server ))

console.log(result);
