javascript - 从JS日期对象获取YYYYMMDD格式的字符串？(Get String in YYYYMMDD format from JS date object?)

Question

I'm trying to use JS to turn a date object into a string in YYYYMMDD format.

(我正在尝试使用JS将date object转换为YYYYMMDD格式的字符串。)

Is there an easier way than concatenating Date.getYear() , Date.getMonth() , and Date.getDay() ?

(有没有比串联Date.getYear() ， Date.getMonth()和Date.getDay()更简单的方法？)

Altered piece of code I often use:

(我经常使用的修改过的代码：)

Date.prototype.yyyymmdd = function() {
  var mm = this.getMonth() + 1; // getMonth() is zero-based
  var dd = this.getDate();

  return [this.getFullYear(),
          (mm>9 ? '' : '0') + mm,
          (dd>9 ? '' : '0') + dd
         ].join('');
};

var date = new Date();
date.yyyymmdd();
