Question

我如何转换这样的对象

{
  "ID_PROC_GD": "1",
  "DT_INI": "2018-06-06",
  "CD_GD": "1",
  "DT_INI_GD": "2018-05-28",
  ...
}

对此

[
  {
    "name": "DT_INI",
    "value": "2018-06-06"
  },
 ...
]

我正在使用lodash 3.10.1

Answer 1

map始终返回数组类型，并且您可以在迭代器中同时使用value和key：

_.map(obj, (value, name) => ({name, value}))

const obj = {
  "ID_PROC_GD": "1",
  "DT_INI": "2018-06-06",
  "CD_GD": "1",
  "DT_INI_GD": "2018-05-28",
}

const result = _.map(obj, (value, name) => ({
  name,
  value
}))

console.log(result)

Answer 2

您可以使用Object.entries()和array#map。

let data = { "ID_PROC_GD": "1", "DT_INI": "2018-06-06", "CD_GD": "1", "DT_INI_GD": "2018-05-28"},
    result = Object.entries(data).map(([name, value]) => ({name, value}));
console.log(result);

您可以使用map

let data = { "ID_PROC_GD": "1", "DT_INI": "2018-06-06", "CD_GD": "1", "DT_INI_GD": "2018-05-28"},
    result = _.map(data, (value, name) => ({name, value}));
console.log(result);

Answer 3

 let obj = {
  "ID_PROC_GD": "1",
  "DT_INI": "2018-06-06",
  "CD_GD": "1",
  "DT_INI_GD": "2018-05-28" 
}

function getNameValObj(ele) {
  return {name: ele, value:obj[ele]};
}
 
let objList = _.flatMap(Object.keys(obj), getNameValObj);

Answer 4

您可以尝试以下方法：

let obj={
  "ID_PROC_GD": "1",
  "DT_INI": "2018-06-06",
  "CD_GD": "1",
  "DT_INI_GD": "2018-05-28",
}
_.map(obj,(item,index)=>({
    ['name']:index,
    ['value']:item
}))

使用lodash 3将对象转换为对象数组
