Question

我正在尝试创建一个Array of Years。当年和去年。以下代码正在运行，但是我想看看是否有更简洁的方法呢？

libm.so

Answer 1

试试这个

   var d = new Date();
   var currentYear = d.getFullYear();
   var lastYear = currentYear - 1;
   $scope.years = [currentYear,lastYear];

Answer 2

避免重复

var d = new Date();
var currentYear = (d.getFullYear());
var lastYear = (currentYear - 1); //Remove another call to d.getFullYear()

$scope.years = [
    currentYear,
    lastYear
];

如果您之后没有使用变量currentYear，您甚至可以将其缩小为：

var d = new Date();
var currentYear = (d.getFullYear());

$scope.years = [
    currentYear,
    currentYear - 1
];

Answer 3

您可以像这样轻松获取当前年份

在您的 .ts 文件中：

public getYear() {
    return new Date().getUTCFullYear();
  }

然后你可以像这样在你的html文件上使用

{{getYear()}}

创建当前年度和去年角度的数组
