问题描述

我有一个日期对象。 如何呈现以下代码段的标题部分?

I have a Date object. How do I render the title portion of the following snippet?

<abbr title="2010-04-02T14:12:07">A couple days ago</abbr>

我有另一个图书馆的相对时间部分。

I have the "relative time in words" portion from another library.

我尝试过以下操作:

function isoDate(msSinceEpoch) {

   var d = new Date(msSinceEpoch);
   return d.getUTCFullYear() + '-' + (d.getUTCMonth() + 1) + '-' + d.getUTCDate() + 'T' +
          d.getUTCHours() + ':' + d.getUTCMinutes() + ':' + d.getUTCSeconds();

}

但这给了我:

"2010-4-2T3:19"


推荐答案

已经有一个名为 toISOString()

There is already a function called toISOString():

var date = new Date();
date.toISOString(); //"2011-12-19T15:28:46.493Z"

如果,不知何故,你是关于浏览器不支持,我已经覆盖了:

If, somehow, you're on a browser that doesn't support it, I've got you covered:

if ( !Date.prototype.toISOString ) {
  ( function() {

    function pad(number) {
      var r = String(number);
      if ( r.length === 1 ) {
        r = '0' + r;
      }
      return r;
    }

    Date.prototype.toISOString = function() {
      return this.getUTCFullYear()
        + '-' + pad( this.getUTCMonth() + 1 )
        + '-' + pad( this.getUTCDate() )
        + 'T' + pad( this.getUTCHours() )
        + ':' + pad( this.getUTCMinutes() )
        + ':' + pad( this.getUTCSeconds() )
        + '.' + String( (this.getUTCMilliseconds()/1000).toFixed(3) ).slice( 2, 5 )
        + 'Z';
    };

  }() );
}
