Javascript - convert number to month name
提问by peaceduck
I have a very simple problem but for some reason I can't find the answer for it.
我有一个非常简单的问题，但由于某种原因我找不到答案。
label.forEach(function(value){
months.push(value['month']);
revenue.push(value['revenue']);
});
The labelis an array of numbers and revenue, in my case this is
这label是一组数字和收入，在我的情况下是
[
{month: 9, revenue: 400},
{month: 11, revenue: 500},
{month: 12, revenue: 600}
]
This is a forEach loop in javascript, it pushes revenue and a month number into two seperate arrays, the problem is that the month is a number (e.g. 12) but I want the .push() to push a month name instead (December), I can't seem to find anything so I was hoping anyone here could help me out.
这是 javascript 中的 forEach 循环，它将收入和月份数字推送到两个单独的数组中，问题是月份是一个数字（例如 12），但我希望 .push() 改为推送月份名称（12 月） ，我似乎找不到任何东西，所以我希望这里的任何人都可以帮助我。

You can try the following:
您可以尝试以下操作：
var label = [{month: 9, revenue: 400},
{month: 11, revenue: 500},
{month: 12, revenue: 600}]
var months = [];
var revenue = [];
var m = [ "January", "February", "March", "April", "May", "June",
"July", "August", "September", "October", "November", "December" ];
label.forEach(function(value){
var monthName = m[value.month - 1];
months.push(monthName);
revenue.push(value.revenue);
});
console.log('Months Array: ', months);
console.log('Revenue Array:', revenue);回答by Arslan Nawaz
<script src="https://momentjs.com/downloads/moment.min.js"></script>
var monthNumber='03';
var month = [ "January", "February", "March", "April", "May", "June",
"July", "August", "September", "October", "November", "December" ];
var monthIndex = moment().month(monthNumber[1]-1).format("M");
var selectedMonthName = month[monthIndex-1];
alert(selectedMonthName);
