我试图使用JS将日期对象转换为YYYYMMDD格式的字符串。有没有比连接Date.getYear(), Date.getMonth()和Date.getDay()更简单的方法?
当前回答
<pre>Date.prototype.getFromFormat = function(format) {
var yyyy = this.getFullYear().toString();
format = format.replace(/yyyy/g, yyyy)
var mm = (this.getMonth()+1).toString();
format = format.replace(/mm/g, (mm[1]?mm:"0"+mm[0]));
var dd = this.getDate().toString();
format = format.replace(/dd/g, (dd[1]?dd:"0"+dd[0]));
var hh = this.getHours().toString();
format = format.replace(/hh/g, (hh[1]?hh:"0"+hh[0]));
var ii = this.getMinutes().toString();
format = format.replace(/ii/g, (ii[1]?ii:"0"+ii[0]));
var ss = this.getSeconds().toString();
format = format.replace(/ss/g, (ss[1]?ss:"0"+ss[0]));
var ampm = (hh >= 12) ? "PM" : "AM";
format = format.replace(/ampm/g, (ampm[1]?ampm:"0"+ampm[0]));
return format;
};
var time_var = $('#899_TIME');
var myVar = setInterval(myTimer, 1000);
function myTimer() {
var d = new Date();
var date = d.getFromFormat('dd-mm-yyyy hh:ii:ss:ampm');
time_var.text(date);
} </pre>
use the code and get the output like **26-07-2017 12:29:34:PM**

似乎mootools提供了Date().format(): https://mootools.net/more/docs/1.6.0/Types/Date
但我不确定是否值得只针对这个特定的任务。
Moment.js可以成为你的朋友
var date = new Date();
var formattedDate = moment(date).format('YYYYMMDD');
new Date('Jun 5 2016').
toLocaleString('en-us', {year: 'numeric', month: '2-digit', day: '2-digit'}).
replace(/(\d+)\/(\d+)\/(\d+)/, '$3-$1-$2');
// => '2016-06-05'
有些日期=新日期(); =某物。 游戏机。log (dateFormated);
从ES6开始,你可以使用模板字符串使它更短:
var now = new Date();
var todayString = `${now.getFullYear()}-${now.getMonth()}-${now.getDate()}`;
这个解决方案没有零垫。看看其他好的答案,看看如何做到这一点。
