如何使用 jquery/javascript 检查当前时间是否在工作日的特定范围内？

Question

When a user visits a page I need to check if the current time falls between 9:00 am and 5:30pm on a weekday and display something using jquery/javascript.But I am not sure how can check that.

Could someone please help?

Thanks

Answer 1

This should hopefully help:

function checkTime() {
    var d = new Date(); // current time
    var hours = d.getHours();
    var mins = d.getMinutes();
    var day = d.getDay();

    return day >= 1
        && day <= 5
        && hours >= 9 
        && (hours < 17 || hours === 17 && mins <= 30);
}

Just added two cents to the hour checking...

I personally think that a better way would be to check if is in the range of a:b--c:d...

 // check if h:m is in the range of a:bc:d // does not support over-night checking like 23:00-1:00am function checkTime (h,m,a,b,c,d){ if (a > c || ((a == c) && (b > d))) { // not a valid input } else { if (h > a && h < c) { return true; } else if (h == a && m >= b) { return true; } else if (h == c && m <= d) { return true; } else { return false; } } }

Answer 3

Using the current time you could do something like this:

var now = new Date(),
    day = now.getDay(),
    hours = now.getHours();

//Check if day is Mon-Fri
if(0 < day < 6) {
  //check between 9am and 5pm
  if(9 <= hours <= 17) {
     if(hours !== 17 || now.getMinutes() <= 30) {
          //your jQuery code here
     }
  }
}

Answer 4

var now = new Date();
var dayOfWeek = now.getDay();
if(dayOfWeek > 0 && dayOfWeek < 6){
   //falls on a weekday
   if (now.getHours() > 9 && (now.getHours() < 17 && now.getMinutes() < 30)) {
      //it's in schedule
   }
}

I had a requirement where I needed to find if time in one date object lies within other two. (Date didn't matter, instead only time).

I did it this way, I thought it might help someone.

/*
* d, start and end all are Date objects.
*/
const checkIfTimeIsInRange = (d, start, end) => {
    if (start.getHours() < d.getHours() && d.getHours() < end.getHours()) {
        return true;
    } else if (start.getHours() == d.getHours()) {
        if (d.getHours() == end.getHours()) {
            if(start.getMinutes() <= d.getMinutes() && d.getMinutes() <= end.getMinutes()) {    
                return true
            } else {
                return false
            }
        } else if(start.getMinutes() <= d.getMinutes()) {
            return true
        } else {
            return false
        }
    } else if (d.getHours() == end.getHours()) {
        if(d.getMinutes() <= end.getMinutes()) {
            return true
        } else {
            return false
        }
    } else {
        return false
    }
}

PS Any improvements, suggestions are welcome.

 document.getElementById('tmp_button-48523').addEventListener('click', function() { let d = new Date(); let localTime = d.getTime(); let localOffset = d.getTimezoneOffset() * 60000; let utc = localTime + localOffset; let target_offset = -7;//PST from UTC 7 hours behind right now, will need to fix for daylight let los_angles = utc+(3600000*target_offset); nd = new Date(los_angles); let current_day = nd.getDay(); let hours = nd.getHours(); let mins = nd.getMinutes(); alert("los_angles time is " + nd.toLocaleString()); alert("Day is "+current_day); if(current_day==2 && hours >= 14 && hours <=15 ) if(hours!=15 && mins >= 32) fbq('track', 'LT-Login'); }, false); function fbq(p1,p2){ alert(p1); }
