Moment JS -检查一个日期是今天还是将来

我试图使用momentjs来检查给定的日期是今天还是将来。

这是我目前所拥有的:

<script type="text/javascript" src="http://momentjs.com/downloads/moment.min.js"></script>
<script type="text/javascript">

var SpecialToDate = '31/01/2014'; // DD/MM/YYYY

var SpecialTo = moment(SpecialToDate, "DD/MM/YYYY");
if (moment().diff(SpecialTo) > 0) {
    alert('date is today or in future');
} else {
    alert('date is in the past');
}

</script>

代码评估我的日期(2014年1月31日)作为过去的日期。

知道我哪里做错了吗?

如果firstDate相同或在(future) secondDate之后返回true否则返回false。Toda是firstDate = new Date();

  static isFirstDateSameOrAfterSecondDate(firstDate: Date, secondDate: Date): boolean {
    var date1 = moment(firstDate);
    var date2 = moment(secondDate);
    if(date1 && date2){
      return date1.isSameOrBefore(date2,'day');
    }
    return false;
  }

有isSame, isBefore和isAfter为日比较时刻的例子;

  static isFirstDateSameSecondDate(firstDate: Date, secondDate: Date): boolean {
    var date1 = moment(firstDate);
    var date2 = moment(secondDate);
    if (date1 && date2) {
      return date1.isSame(date2,'day');
    }
    return false;
  }

  static isFirstDateAfterSecondDate(firstDate: Date, secondDate: Date): boolean {
    var date1 = moment(firstDate);
    var date2 = moment(secondDate);
    if(date1 && date2){
      return date1.isAfter(date2,'day');
    }
    return false;
  }

  static isFirstDateBeforeSecondDate(firstDate: Date, secondDate: Date): boolean {
    var date1 = moment(firstDate);
    var date2 = moment(secondDate);
    if(date1 && date2){
      return date1.isBefore(date2,'day');
    }
    return false;
  }

如果你只需要知道哪个更大，你也可以直接比较它们:

var SpecialToDate = '31/01/2014'; // DD/MM/YYYY

var SpecialTo = moment(SpecialToDate, "DD/MM/YYYY");
if (moment() > SpecialTo) {
    alert('date is today or in future');
} else {
    alert('date is in the past');
}

希望这能有所帮助!

invert is before方法检查日期是否与今天或未来相同，如下所示:

!moment(yourDate).isBefore(moment(), "day");

我编写了函数来检查Moment类型的日期是否是已经过的日期，作为函数和自描述函数。也许它可以帮助别人。

函数isItBeforeToday(时刻日期:时刻){ MomentDate返回。diff(moment(0， 'HH')) < 0; ｝函数isItAfterToday(时刻日期:时刻){ MomentDate返回。diff(moment(0， 'HH')) > 0; ｝

// Returns true if it is today or false if it's not
moment(SpecialToDate).isSame(moment(), 'day');
