我将如何在此对象数组上使用_.mapKey

Question

我有以下对象数组。 我想将键“文本”更改为标签

[
  {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

您可以使用.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

您可以将函数forEach和带有目标的数组一起使用

此替代方法将使原始数组变异。

 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);
