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']

我需要输出格式如下，

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

有没有办法实现这个目标？

Answer 1

您可以按如下方式使用Array.prototype.reduce()：

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);

Answer 2

试试这个解决方案

var a = ['N','Normal','S','Severe','C','Confidential']
var output = [];
for (var i = 0; i < a.length; i++) {
  var tmpObj = {};
  if (i%2 == 0) {
    tmpObj.code = a[i];
    if (a[i+1]) {
      tmpObj.description = a[i+1];
    }
    output.push(tmpObj);
  }
}
console.log(output);
