如何在JS中将JSON对象转换为键值对？

Question

{"1":"val1","2":"val2","3":"val3"}我希望它像这样转换：{"Id":"1","value":"val1","Id":"2","value":"val2","Id":"3","value":"val3"}小帮助 请多见识

Answer 1

不能在一个对象中使用相同的键名。

相反，你可以这样做。

const origin = {"1":"val1","2":"val2","3":"val3"}

const converted = Object.entries(origin).map( ([key,value]) => ({id: key, value }) );

console.log(converted);

Answer 2

 const obj = {"1":"val1","2":"val2","3":"val3"}

  const newObject = Object.keys(obj).map(e => {

 return {ID: e , value : obj[e] }

   });

  console.log(newObject); // [ { ID: '1', value: 'val1' },

                                { ID: '2', value: 'val2' },

                              { ID: '3', value: 'val3' } ]

Answer 3

const data = {"1":"val1","2":"val2","3":"val3"};

const result = Object.keys(data).map((key) => ({ id: key, value: data[key] }));

结果将是[{ id: "1", value: "val1" }, { id: "2", value: "val2" }, { id: "3", value: "val3" }]

Answer 4

正如所指出的，这是无稽之谈。如果你想转换它，如果看起来像这样：

[{"Id":"1","value":"val1"},{"Id":"2","value":"val2"},{"Id":"3","value":"val3"}]

您可以创建一个函数来转换它。

const object = {"1":"val1","2":"val2","3":"val3"};

console.log(Convert(object));

function Convert(obj){

  return Object.keys(obj).map(i => ({Id: i, value: obj[i]}));

}
