javascript - moment.js-测试日期是今天，昨天还是一周或两周前

我正在尝试使用moment.js来确定日期是今天，昨天，1周之前或更早(2周或更早)。

我已经在前两种情况下做到了:

var today = moment().startOf('day');
var yesterday = moment().subtract(1, 'days').startOf('day');

if (moment(localTime).isSame(today, 'd')) // today
    // do something
if (moment(localTime).isSame(yesterday, 'd')) // yesterday
    // do something

那是对的吗？

但是，如何检查日期是一周前或更晚(例如两周前)？

最佳答案

这可能是有用的:

var REFERENCE = moment("2015-06-05"); // fixed just for testing, use moment();
var TODAY = REFERENCE.clone().startOf('day');
var YESTERDAY = REFERENCE.clone().subtract(1, 'days').startOf('day');
var A_WEEK_OLD = REFERENCE.clone().subtract(7, 'days').startOf('day');

function isToday(momentDate) {
    return momentDate.isSame(TODAY, 'd');
}
function isYesterday(momentDate) {
    return momentDate.isSame(YESTERDAY, 'd');
}
function isWithinAWeek(momentDate) {
    return momentDate.isAfter(A_WEEK_OLD);
}
function isTwoWeeksOrMore(momentDate) {
    return !isWithinAWeek(momentDate);
}

console.log("is it today? ..................Should be true: "+isToday(moment("2015-06-05")));
console.log("is it yesterday? ..............Should be true: "+isYesterday(moment("2015-06-04")));
console.log("is it within a week? ..........Should be true: "+isWithinAWeek(moment("2015-06-03")));
console.log("is it within a week? ..........Should be false: "+isWithinAWeek(moment("2015-05-29")));
console.log("is it two weeks older or more? Should be false: "+isTwoWeeksOrMore(moment("2015-05-30")));
console.log("is it two weeks older or more? Should be true: "+isTwoWeeksOrMore(moment("2015-05-29")));
