使用moment.js来确定unix时间戳是否在上周内

Question

How do i use unix timestamp to work out if an event was within the last week?

I tried

moment().subtract('weeks', 1).unix()<item.start

but it is returning unexpected results. thanks so much

edit: thanks so much for the question feedback here is an example of my response

Answer 1

You can create the point of time which represents the lowest valid value as you did before. When you have this point in time, you can check with momentjs if a given date is older.

const weekAgo = moment().subtract(1, 'weeks') // This is the time to check

const ts = 1519945200000 // any unix timestamp. This is 2018-03-01
const m1 = moment(ts) // Use a unixtimestamp to create a moment object

const m2 = moment().subtract(8, 'days') // further test data
const m3 = moment().subtract(6, 'days') // further test data

console.log(weekAgo.isBefore(m1)) // true
console.log(weekAgo.isBefore(m2)) // true
console.log(weekAgo.isBefore(m3)) // false

Answer 2

You can check this answer for date range checking

You can use one of the moment plugin -> moment-range to deal with date range:

 var startDate = new Date(2013, 1, 12)   , endDate   = new Date(2013,
 1, 15)   , date  = new Date(2013, 2, 15)   , range =
 moment().range(startDate, endDate);

 range.contains(date); // false

Answer 3

Will be using moment.diff function

Follow these Steps

1. Convert unix timestam to moment object
2. Format date

3. use moment.diff

    function dateDiff (date) { // date is unix timestamp date let d = moment(date); if ( d.isValid() ) { d.format("YYYY-MM-DD"); // moment() gives current date-time return moment().diff(d, 'weeks', true); // If past date then result will be positive if future date then negative. } else return null; } console.log( dateDiff( 1519945200000 ) ); // 30.648079404761905 // 30 weeks ago console.log( dateDiff( 1534395200000 ) ); // 6.755883640873016 // 6 weeks ago console.log( dateDiff( 1529945200000 ) ); // 14.113687873677248 // 14 weeks ago console.log( dateDiff( 1541945200000 ) ); // -5.7275819675925925 // 5 weeks in future 

Answer 4

As @be-ndee said it was just milliseconds vs seconds so i just edited it to

moment().subtract('weeks', 1).unix()
