我如何在这个对象数组上使用_.mapKey

Question

我有以下对象数组。我想将关键“文本”更改为名称标签

[
  {id: 0, text: "blue"},

  {id: 1, text: "green"},

  {id: 2, text: "orange"},

  {id: 3, text: "yellow"}
]

“id”必须保持原样。

我可以使用lodash或javascript。

Answer 1

您可以使用.map()方法重命名对象数组中的键。

var data = [
  {id: 0, text: "blue"},

  {id: 1, text: "green"},

  {id: 2, text: "orange"},

  {id: 3, text: "yellow"}
]

data = data.map(el => {
  return {
    id: el.id,
    label: el.text
  }
})

console.log(data);

Answer 2

你可以使用.map

let arr=[
  {id: 0, text: "blue"},

  {id: 1, text: "green"},

  {id: 2, text: "orange"},

  {id: 3, text: "yellow"}
];

let arr1=[];
arr1=arr.map(a=>({id:a.id,label:a.text}));
console.log(arr1);

Answer 3

您可以使用函数forEach和带有目标的数组

此替代方案将改变原始数组。

let array = [{id: 0, text: "blue"},{id: 1, text: "green"}, {id: 2, text: "orange"},  {id: 3, text: "yellow"}],
    target = [['text', 'label'], ['ele', 'stack']];

array.forEach(o => {      
  target.forEach(([src, dest]) => {
    if (o[src]) {
      Object.assign(o, {[dest]: o[src]});
      delete o[src];
    }
  });
});
    
console.log(array);

.as-console-wrapper { max-height: 100% !important; top: 0; }
