I have a curTime variable that is the current time using new Date() and a pwChangeDate value called from the backend data.
let curTime = new Date(); // Thu Oct 27 2022 15:02:34 GMT 0900
const pwDate = new Date(pwChangeDate) // Thu Oct 20 2022 13:51:57 GMT 0900
At this time, when pwDate passes 90 days based on curTime, I want to display an alert saying "90 days have passed." and when 83 days have passed, "7 days left out of 90 days." I want to display an alert.
but if i use my code it doesn't work how can i fix it?
const pwChangeDate = cookie.get('pwChangeDate');
const pwDate = new Date(pwChangeDate)
if (curTime.getDate() >= pwDate.getDate() - 90) {
alert('90 days have passed.')
}
if (curTime.getDate() >= pwDate.getDate() - 7) {
alert('7 days left out of 90 days..')
}
CodePudding user response:
you can get the diff between current data and pwDate in days like this:
const pwDate = new Date('Thu Oct 20 2022 13:51:57 GMT 0900');
const diff = Math.floor((new Date - pwDate)/1000/60/60/24);
console.log(diff)
CodePudding user response:
If you want to calcuate the days difference between pwDate
and curTime
, you can calculate like this.
Math.floor((pwDate.getTime() - curTime.getTime()) / (1000 * 60 * 60 * 24));
getTime()
method returns a time value as milliseconds.
1000 * 60 * 60 * 24
is milliseconds per day.
OR
Using some library. (date-and-time)
