Add properties from one array of objects to another

Question

I have the following Angular 1.0 controller:

function EventListController($timeout, eventService) {
  var vm = this;
  vm.events = getEvents();
  vm.calendar buildCalendar();
}

The variable vm.events is something like:

vm.events = [
  { date: "2016-09-22T12:05:42.03", id: 12 }, 
  { date: "2016-09-25T12:05:42.03", id: 14 }
];

The variable calendar is the following:

vm.calendar = {
  weeks: [
    { days: [ { date: "2016-09-12T12:05:42.03" }, ... ] }
    { days: [ { date: "2016-09-22T12:05:42.03" }, ... ] }
  ]
}

I need to go through all events dates and add the ID property to the calendar date of the same DAY. Calendar weeks has all days of that month. In this case is September 2016.

How can I do this?

compare like new Date("2016-09-22T12:05:42.03").setHours(0,0,0,0) == new Date("2016-09-22T09:05:42.03").setHours(0,0,0,0) — Satpal

You need to iterate both objects. You can use Date constructor to create Date object and the use setHours(0,0,0,0) to set hours, mins.. as zero, then you can only compare date.

var vm = {};
vm.events = [{
  date: "2016-09-22T12:05:42.03",
  id: 12
}, {
  date: "2016-09-25T12:05:42.03",
  id: 14
}];
vm.calendar = {
  weeks: [{
    days: [{
      date: "2016-09-25T09:05:42.03"
    }]
  }]
};

vm.calendar.weeks.forEach(function(w) {
  w.days.forEach(function(d) {
    var e = vm.events.filter(function(e) {
      return new Date(e.date).setHours(0, 0, 0, 0) == new Date(d.date).setHours(0, 0, 0, 0);
    });
    if (e.length) {
      d.id = e[0].id;
    }
    console.log(d)
  })
});

//console.log(vm.calendar.weeks)
