Question

我想以2019年5月9日的格式获取当前时间。

String output = input.replaceAll("^.{3}(.*).$", "$1");

此处输出以2019/05/09格式显示当前时间。我应如何获取“ May 05，2019”格式。

Answer 1

尝试一下

var d = new Date();
var months = new Array('January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December');
var month = months[d.getMonth()]
var day = d.getDate();
var y=d.getFullYear();

var today =  month +" " +day + "," +  y;

console.log(today);

Answer 2

您可以使用以下方法来代替创建（并维护）自己的名称数组：

d.toLocaleString('en-us', { month: 'long' });

var d = new Date();
var month = d.toLocaleString('en-us', { month: 'long' });
var day = d.getDate();
var y=d.getFullYear();

var today =  month +" " +day + "," +  y;    
console.log(today);

Answer 3

您可以这样做

 var monthNames = [
    "Jan", "Feb", "Mar",
    "Apr", "May", "Jun", "Jul",
    "Aug", "Sep", "Oct",
    "Nov", "Dec"
  ];

  var d = new Date();
  var day = d.getDate();
  var monthIndex = d.getMonth();
  var year = d.getFullYear();

  var output = monthNames[monthIndex] + ' 'day + ' ,' + year;

Answer 4

这正是您要寻找的

function LogCurrentDate(e){
   var date = new Date();
   var options = { year: 'numeric', month: 'long', day: '2-digit' };
   $(".output").empty().append("<p>" + date.toLocaleDateString('en-US', options) + "</p>");
};

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div>
  <button onclick="LogCurrentDate(event)">Show Date</button>
</div>
<div class="output"></div>

以这种格式获取当前日期“ 2019年5月9日”
