How to check selected time is within the given time range in Javascript

Question

I need to determine if the selected times (start time, end time) by the user is in the array of appointment times.

I get the appointment times from exchange web service and the output is :

[{Status: "Busy", StartTime: "2016-10-05T11:00:00+10:00", EndTime: "2016-10-05T11:30:00+10:00"},{Status: "Busy", StartTime: "2016-10-05T13:00:00+10:00", EndTime: "2016-10-05T15:30:00+10:00"}]

The times that user has selected are :

var start_time = Date.parse("2016-10-05T14:30");
var end_time = Date.parse("2016-10-05T15:00");

So far I have tried the following but I am not sure if this is the correct way to do it:

var data = [{Status: "Busy", StartTime: "2016-10-05T11:00:00+10:00", EndTime: "2016-10-05T11:30:00+10:00"},{Status: "Busy", StartTime: "2016-10-05T13:00:00+10:00", EndTime: "2016-10-05T15:30:00+10:00"}];

for (var key in data)
{
  var obj = data[key];
  if (obj['Status'] == 'Busy')
  {
    check_open_time_val = Date.parse(obj['StartTime']);
    check_close_time_val = Date.parse(obj['EndTime']);

     if (check_open_time_val > open_time)
     {
        console.log('Is Busy');
        // break;
        return true;
      }
   }else {
      console.log(obj['Status'] + 'XXXXX');
   }
  }

How do I check if the start_time and the endtime are not in any of the appointment times. Thanks

Are you wanting to detect if there's any overlap with the user time range and the busy time ranges? — Phil, Oct 05 '16 at 06:27

You can combine this logic with Array.prototype.some

let data = [{Status: "Busy", StartTime: "2016-10-05T11:00:00+10:00", EndTime: "2016-10-05T11:30:00+10:00"},{Status: "Busy", StartTime: "2016-10-05T13:00:00+10:00", EndTime: "2016-10-05T15:30:00+10:00"}],
    start_time = Date.parse("2016-10-05T14:30:00+10:00"),
    end_time = Date.parse("2016-10-05T15:00:00+10:00");

let isClash = data.some(obj => {
    let s = Date.parse(obj.StartTime), e = Date.parse(obj.EndTime);

    return obj.Status === 'Busy' && start_time <= e && end_time >= s;
});

console.log('is clash?', isClash);

Note that I aligned the UTC offsets of your start_time and end_time so you could see that it works :)
