I'm trying to get the start and the end a a specific day.
Here's the code:
var newDay, newDayEnd, newDayStart;
if (newDay === '') {
newDay = moment();
}
newDay.subtract('day', 1);
newDayStart = newDay.startOf('day');
newDayEnd = newDay.endOf('day');
I'm trying to debug it, and I noticed that when if goes trough the values are correct, but as soon as it reaches newDay.endOf('day') it sets all the variable to the end of the specified day (23.59.59)
I'm using the above function on button click. Every time I click a button, it goes back one day (newDay.subtract('day', 1)) and I need to be able to get start and end of the new day (newDay variable)
Any help?
What am I doing wrong here? I don't understand.
Thanks
Moment objects are mutable, so you have to clone() them before modifying them.
As you can read from the endOf docs:
Mutates the original moment by setting it to the end of a unit of time.
Working example:
var newDay, newDayEnd, newDayStart;
newDay = moment().subtract(1, 'day');
newDayStart = newDay.clone().startOf('day');
newDayEnd = newDay.clone().endOf('day');
console.log(newDayStart.format(), newDayEnd.format());

I am new to script and found a code that I have been tweaking for my needs but I keep running into a problem since I separated the date and time. My date field display and selected value match but the time fields keep defaulting to MM/DD/YY HH:MM A/P when selected. en I click on it (it displays correctly when not selected). I need to have the field only display the time and nothing else. so it will stop causing issues to my formulas on other sheets. I know my problem lies in the last part but so far what I have tried has failed.
//DEFINE ALL ACTIVE SHEETS
var ss = SpreadsheetApp.getActiveSpreadsheet();
//DEFINE MAIN SHEET
var mainSheet = ss.getSheetByName("MAIN");
//LAST ROW ON MAIN SHEET
var lastRow = mainSheet.getLastRow();
for (var j = 5; j <= lastRow; j++)
{
// CHECK CLOCK IN
if(mainSheet.getRange('b1:b1').getValue() == mainSheet.getRange(j, 1).getValue() && mainSheet.getRange(j,3).getValue() == '')
{
Browser.msgBox('Need to Clock Out before Clocking IN');
return;
}
}
// ADD CLOCK IN RECORD
mainSheet.getRange(lastRow + 1, 1).setValue(mainSheet.getRange('b1:b1').getValue()).setFontSize(12);
mainSheet.getRange(lastRow + 1, 2).setValue(new Date(new Date().setHours(0, 0, 0, 0))).setNumberFormat('MM/DD/YY').setHorizontalAlignment("center").setFontSize(12);
mainSheet.getRange(lastRow + 1, 3).setValue(new Date()).setNumberFormat("hh:mm A/P").setHorizontalAlignment("center").setFontSize(12);//````
You get a whole bunch of formatting options if you look for Utilities.formatDate
var date = Utilities.formatDate(new Date(), "Europe/Berlin", "dd.MM.yyyy")
var time = Utilities.formatDate(new Date(), "Europe/Berlin", "HH:mm")
Change "Europe/Berlin" to your location to get the current time. Now use the variables wherever you need them. Simple as that.
Pro tip: Try to use variables (just like shown above) for readability instead of fitting everything in one line.
Using SwiftUI (or Combine) how might I set up a series of one or more events that are triggered by the (system) clock. Examples might include:
Every night at midnight,
On the hour,
Every fifteen minutes on the quarter hour,
Finally, on a slightly different note: On the 29th of February 2020 at 12:15.
An approximation is easily achieved by setting up a timer event that fires every second and then checking the hours/minutes/seconds, etc. but this seems very inefficient for events that may be many hours or days apart.
I'm looking for something that is closely synchronised to the actual system clock and fires off a single event at the required time rather than firing loads of events and having each one ask "Are we there yet?".
I would suggest the following:
DispatchQueue.global(qos: .background).async {
let isoDate = "2020-01-13T16:58:30+0000"
let dateFormatter = ISO8601DateFormatter()
let date = dateFormatter.date(from:isoDate)!
let t = Timer(fire: date, interval: 2, repeats: true) { timer in
print("fired")
}
let runLoop = RunLoop.current
runLoop.add(t, forMode: .default)
runLoop.run()
}
string to date conversion I used this answer to format the time correctly.
The example is in GMT.
documentation apple you can look up timer tolerance which can be adjusted if you need the timer to be very accurate.
interval is in seconds so this solution won't get more accurate than seconds
You might want to enable the Background Modes capability to go for the very long running timers. Never done that so I can't help here.
All your examples should work. I hope this helps!
I had to implement this feature too using Combine / SwiftUI : a Timer that would execute at start then every day, hour or minutes (for testing), here is my solution if it can be useful or improved :)
class PeriodicPublisher {
var periodicFormat: PeriodicFormat = .daily
init(_ format: PeriodicFormat = .daily) {
self.periodicFormat = format
}
// Must have an equatable for removeDuplicate
struct OutputDate: Equatable {
let compared: String
let original: String
init(_ comparedDatePart: String, _ originalDate: String) {
self.compared = comparedDatePart
self.original = originalDate
}
static func ==(lhs: OutputDate, rhs: OutputDate) -> Bool {
return lhs.compared == rhs.compared
}
}
enum PeriodicFormat {
case daily
case hourly
case minutely
func toComparableDate() -> String {
switch self {
case .daily:
return "yyyy-MM-dd"
case .hourly:
return "HH"
case .minutely:
return "mm"
}
}
}
func getPublisher() -> AnyPublisher<OutputDate, Never> {
let compareDateFormatter = DateFormatter()
compareDateFormatter.dateFormat = self.periodicFormat.toComparableDate()
let originalTimerDateFormatter = DateFormatter()
originalTimerDateFormatter.dateFormat = "yyyy-MM-dd HH:mm"
var nowDate: Just<OutputDate> {
let comparedDate = compareDateFormatter.string(from: Date())
let originalDate = originalTimerDateFormatter.string(from: Date())
return Just(OutputDate(comparedDate, originalDate))
}
let timerDate = Timer.publish(every: 2.0, tolerance: 1.0, on: .main, in: .default, options: nil)
.autoconnect()
.map { dateString -> OutputDate in
return OutputDate(compareDateFormatter.string(from: dateString), originalTimerDateFormatter.string(from: dateString))
}
.eraseToAnyPublisher()
return Publishers.Merge(nowDate, timerDate)
.map { $0 }
.removeDuplicates()
.eraseToAnyPublisher()
}
}
How does it work ?
Every 2 seconds the scheduler issue current date (with Timer.publish()), this date is used to create a "OutputDate" holding two properties : one "comparable" part used to compare if something has changed and one "original" part so it can be useful for the consumer.
Comparable property is Timer's date formatted with toComparableDate given the provided configuration (.daily, .hourly, .minutely). Using "removeDuplicates" on this property allow to publish "OutputDate" only when this value changes. Every day or hour or minute.
Publishers.Merge is used to publish a value immediately after instantiation, otherwise nothing happens before the first Timer.publish(every). Here 2 seconds.
How to use it ?
You would use it with Combine like this :
PeriodicPublisher(.daily).getPublisher().sink { date in
print("Day has changed \(date.original)")
}
This might be a big ask, but I'm completely stuck so any help is appreciated.
I'm trying to create a countdown timer that runs from Sunday to Sunday and just restarts at the end of the week. I've tried using countdown packages in atmosphere but the documentation is limited and never seems to work. I've also tried to download and run 3rd party jquery packages however they always seem to crash meteor.
Could someone point me in the right direction or show me how to do this in meteor?
Specific details:
Countdown timer used to run an auction.
Auction runs for 7 days, Starts Sunday at 12:00am finishes 7 days
later.
Auction resets and starts again after 7 days.
Countdown timer will be visible by users on multiple pages.
Countdown timer units to be displayed - Days, Hours, Minutes, Seconds (eg.
6 days, 3 hours, 55 minutes, 22 seconds until the next auction
begins.)
The question is too large. But i can suggest the small step to work with this. Your auction scheme will need to have a endDateTime to store the value (even it will start/end in Sunday). On the template you need to display the timer, set one ReactiveVar as number (to count down), one ReactiveVar as string (to display to result)
Template['countDownTemplate'].created = function() {
var due, dueDate, duration, now, num, self;
self = this;
dueDate = Template.instance().data['auction']['endDateTime'];
now = moment.utc();
due = moment.utc(dueDate, 'YYYY-MM-DD hh:mm:ss');
duration = moment.duration(due.diff(now));
num = Math.floor(duration.asSeconds());
if (num >= 0) {
self['remaining'] = new ReactiveVar<number>(num);
self['timeRemaining'] = new ReactiveVar<string>(convertPeriod(num));
self['interval'] = Meteor.setInterval((function() {
var remaining;
remaining = self['remaining'].get();
self['remaining'].set(remaining - 1);
self['timeRemaining'].set(convertPeriod(self['remaining'].get()));
if (remaining === 0) {
Meteor.clearInterval(self['interval']);
} else {
remaining = Math.floor(moment.duration(due.diff(now)).asSeconds());
}
}), 1000);
}
};
(the convertPeriod will be based on the remaining number to convert into your correct format)
The rest is just about showing timeRemaining in the correct format with the convertPeriod
When you drop external item on to fullcalendar it automatically sets start date of the event but end time is null. So what I want to do is set end time to 2h later.
eventReceive: function(event){
event.end = event.start;
console.log(event.start.format()); // 2014-12-14T07:00:00
event.end.add(2, 'h');
console.log(event.start.format()); // 2014-12-14T09:00:00
...
when ever I try to do that event.start is set to exact same time as event.end
EDIT
Solved by forceEventDuration, but still curious about why does it do that?
event.start is an object. You are passing the object reference, not the value. To see how this works in javascript execute this:
var x = {"a": 10}
var y = x
y["a"] = 5
console.log(x)
This will return {"a": 5} because you changed the referenced object. You would need to create a copy (clone) of the object first before you pass it.
I have a global variable 'csId' of string type. In the code below under drawChart() function, in for loop, csID variable should be set to '1' by the modelLocator when i=0 and csId should be set to '2' by modelLocator when i=1.(considering lengh=2).
Alert in drawchart() (for csId) seems to be printing the right 'csid' values(both 1 and 2) but in the dataFunction() 'columnSeries_labelFunc' i am always getting the csId Alert value as '2' and never as '1'.
Please find the code below:
drawchart() function::
public function drawChart():void
{
var cs:ColumnSeries= new ColumnSeries();
var lenght:Number=AppModelLocator.getInstance().ctsModel.productSummary.getItemAt(0).collMgmtOfcList.length;
myChart.series = [cs];
var tempObj:Object;
for(csLoop=0;csLoop<lenght;csLoop++)
{
cs = new ColumnSeries();
this.csId= new String(String(AppModelLocator.getInstance().ctsModel.productSummary.getItemAt(0).collMgmtOfcList[csLoop]));
Alert.show("csId="+this.csId);
cs.id=this.csId;
cs.displayName = 'Exposure';
cs.dataFunction=columnSeries_labelFunc;
myChart.series[csLoop] = cs;
}
columnSeries_labelFunc() function::
private function columnSeries_labelFunc(series:Series, item:Object, fieldName:String):Object {
var col:Number=0;
Alert.show("value of csid in columnSeries_labelFunc="+this.csId);
if(fieldName == "yValue" && series.id==csId){
return(item.exposureUSDList[0]);
}else if(fieldName == "yValue" && series.id==csId) {
return(item.exposureUSDList[1]);
}else if(fieldName == "xValue"){
return(item.rptType);
}else
return null;
}
Please Help!!!
First: Assigning a value to a global variable repeatedly inside a loop is a bad idea. Nothing good will happen from that.
It's hard to tell from the context here, but the most likely reason that you're having this problem is that the flow of execution is as follows:
drawChart() executes synchronously, counting through each step in the loop, creating the ColumnSeries, which are each invalidated, meaning they will redraw on the next frame. The function ends, with csID at the last value it held.
The app goes into the next step in the elastic racetrack and validates the invalidated components.
columnSeries_labelFunc is called, with csID still holding the terminal value from the loop.
The end result being that columnSeries_labelFunc isn't called until you're already completely finished in drawChart.
The simplest fix would be to read the id that you're setting on the series in the label function, rather than relying on a global variable at all.
