angular - 如何将数组转换为json数组对象

Question

我有一个数组说

var a = ['N','Normal','S','Severe','C','Confidential']

我需要如下的输出格式，

[{code:'N',description:'Normal'},
 {code:'S',description:'Severe'},
 {code:'C',description:'Confidential'}
]

有什么办法可以实现吗？

Answer 1

您可以使用 Array.prototype.reduce()如下:

const array = ['N', 'Normal', 'S', 'Severe', 'C', 'Confidential'];
const object = array.reduce((result, value, i) => {
  i % 2 || result.push({code: value, description: array[i + 1]});
  return result;
}, []);

console.log(object);
