datetime - 节点 RRule 检查规则日是否为今天

Question

我在节点中使用“rrule.js”库来解析我的 RRule。我想知道当前日期是否与规则日期相同。它适用于大多数情况，但不是全部。我也是用moment.js来比较的。问题出在“rule.after()”中。它应该包括当天，但没有。

function checkIfToday(rruleStr){
var RRule = require('rrule').RRule;
var moment = require('moment');

var rule = RRule.fromString(rruleStr);

// Convert all dates into UTC before comparison
var todayutc          = moment().utc(); // today in UTC
var nextOccurrence    = rule.after(todayutc,inc=true); // next rule date including today
var nextOccurutc      = moment(nextOccurrence).utc(); // convert today into utc
var match             = moment(nextOccurutc).isSame(todayutc, 'day'); // check if 'DAY' is same

return match;
}

知道什么是最好的方法。

谢谢。

这对我有用。尝试使用 moment 的 startOf 方法将 todayutc 的时间设置回一天的开始:

function checkIfToday(rruleStr){
  var RRule = require('rrule').RRule;
  var moment = require('moment');

  var rule = RRule.fromString(rruleStr);

  // Convert all dates into UTC before comparison
  var todayutc          = moment().utc().startOf('day'); // today in UTC
  var nextOccurrence    = rule.after(todayutc, true); // next rule date including today
  var nextOccurutc      = moment(nextOccurrence).utc(); // convert today into utc
  var match             = moment(nextOccurutc).isSame(todayutc, 'day'); // check if 'DAY' is same

  return match;
}
