将月份编号从JS中的数组转换为月份名称

Question

我以月数的形式从Ajax接收数据

0: 2018 - year
1: 6 - month
2: 7 - day

如何将其转换为月份名称？ 示例：

0: 2018 - year
1: "Jun" - month
2: 7 - day

Answer 1

使用数组：

const monthNames = ["January", "February", "March",  "April", "May", "June",  "July", "August", "September", "October", "November", "December"];

const d = new Date();
document.write("The current month is " + 
monthNames[d.getMonth()]);

或尝试

var date = new Date("10/11/2018"),
locale = "en-us",
month = date.toLocaleString(locale, { month: "long" });

Answer 2

此处：

function monthName(mon) {
   return ['January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'November', 'December'][mon - 1];
}

console.log(monthName(7));

当您准备使用更专业的解决方案时，请使用moment.js

Answer 3

let data = {
 0: 2018,
 1: 6,
 2: 7
}
let months = ['January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'November', 'December']

如果您始终在响应的数据对象的索引1处拥有月份，则可以直接将其设置为定义的月份名称。

data[1] = months[data[1]-1];

这将是输出

{ 
  0: 2018, 
  1: 'June', 
  2: 7 
}
