I have a highchart which displayed the last x datapoints I measured.
This can be a few days or some hours.
When I have some hours, I want to display "HH:mm". And when it's midnight I want to display "HH:mm DD.MM.JJJJ".
But when I displayed a few days I only want to display "DD.MM.JJJJ"
I found a solution:
formatter: function() {
if (this.axis.tickPositions.length > 2 && (this.axis.tickPositions[1] - this.axis.tickPositions[0]) < (24 * 3600 * 1000)) {
if (this.dateTimeLabelFormat == format_days) {
this.dateTimeLabelFormat = format_minutes + "<br />" + format_days;
}
}
return this.axis.defaultLabelFormatter.call(this);
But I'm sure there is an nicer solution.
You can change dateTimeLabelFormats object to display specific date format on a specific unit.

Currently, in the User Report view of Google Analytics, I get timestamps on each event, but it is only down to the minute, not the second. I can't find a setting in GA that changes that column.
My goal is to pass this timestamp through GTM, perhaps as "tag label", so that I can see it in GA.
How do I create a timestamp variable in GTM?
Create a custom javascript variable (i.e. a variable that contains a function, not a "javascript" variable that just reads a global variable), and give it a name, e.g. "timestamp".
Custom javascript variables are anonymous functions with a return value.
The current way to get a timestamp is Date.now(). This might not be supported by older browser (especially IE 8 and lower), so you might use new Date().getTime(); as an alternative.
The variable body would be as simple as:
function() {
return Date.now();
}
and you would use that in a tag by surrounding the variable name with double curly parenthesis, e.g. {{timestamp}}. Date.now() returns milliseconds ( elapsed since 1 January 1970 00:00:00 UTC), so you might want to divide by thousand.
Alternatively you could create a datetime variable that includes seconds and even milliseconds. I think this was originally by Simo Ahava:
function() {
// Get local time as ISO string with offset at the end
var now = new Date();
var tzo = -now.getTimezoneOffset();
var dif = tzo >= 0 ? '+' : '-';
var pad = function(num) {
var norm = Math.abs(Math.floor(num));
return (norm < 10 ? '0' : '') + norm;
};
return now.getFullYear()
+ '-' + pad(now.getMonth()+1)
+ '-' + pad(now.getDate())
+ 'T' + pad(now.getHours())
+ ':' + pad(now.getMinutes())
+ ':' + pad(now.getSeconds())
+ '.' + pad(now.getMilliseconds())
+ dif + pad(tzo / 60)
+ ':' + pad(tzo % 60);
}
which returns a formatted string like 2016-08-02T09:22:44.496+02:00.
The second it's not accesible via Google Analytics. The closest way to do this is via Google Big Query,but this last is only available for premium members.
Maybe you can add the timeStamp as CustomDimentions
function getdateGA(){
return Date();
}
ga('send', 'event', 'category', 'action', {
'dimention1': getdateGA()
});
The date format is not the best one, try to find the best for you modifing the getdateGA function

I want to use fullcalendar with custom date range for ex. it should display view for particular date range like from 15th April to 4th May(Spans between two months).
Any suggestions?.
you can call this function to gt events in date range. but this will bring you only 30 days evnt. if you pass dates like '01-may-2013' to 15-June-2013' then it will show data from 01-may2013 to 30st may 2013. Lt me know if you can find any clue for this issue.
function GetAgendaEvents(datefrom, dateTo) {
var fromDate = new Date($("#from").val());
var toDate = new Date($("#to").val());
if (fromDate.getTime() <= toDate.getTime()) {
$('#fullcal').fullCalendar('removeEvents').fullCalendar('addEventSource', events);
$('#fullcal').fullCalendar('refetchEvents');
var filteredEvent = $('#fullcal').fullCalendar('clientEvents', function (event) {
return event.start >= fromDate && event.start <= toDate;
});
$('#fullcal').fullCalendar('gotoDate', fromDate.getFullYear(), fromDate.getMonth(), fromDate.getDate());
$('#fullcal').fullCalendar('changeView', 'agenda'/* or 'basicDay' */);
$('#fullcal').fullCalendar('removeEvents').fullCalendar('addEventSource', filteredEvent);
$('#fullcal').fullCalendar('refetchEvents');
}
}
Can you please tell me how to format date with time in jquery template like this:
11/9/2011 12:00:00 AM
I am using this function which only formats the date part and hide the time portion of it:
function (jsonDate) {
var value = new Date(parseInt(jsonDate.substr(6)));
return value.getMonth() + 1 + "/" + value.getDate() + "/" + value.getFullYear();
}
How about:
function (jsonDate) {
var value = new Date(parseInt(jsonDate.substr(6)));
return value.toUTCString();
}

By default if you enable the 'selectable' attribute it will allow you to click and drag and select several days. I would like to only allow the user to select a single day, not drag over multiple. Is there a way to have 'selectable' enabled, but disable the dragging feature that comes along with it?
If you want to limit highlight to a single day in agenda week view you can use following:
selectConstraint:{
start: '00:01',
end: '23:59',
},
if you want to limit the event you can use
eventConstraint:{
start: '00:00',
end: '24:00',
},
in the select callback, adding the following does the trick:
(fullcalendar 2 using moment.js)
if (start.add('days', 1).date() != end.date() )
$scope.eventCal.fullCalendar('unselect');
resources:
http://arshaw.com/fullcalendar/docs/selection/select_callback/
http://arshaw.com/fullcalendar/docs/selection/unselect_method/
You can select a single date or time by passing fullcalendar's 'select' method to the dayClick event listener:
$('#myCalendar').fullcalendar({
dayClick: function(date,jsEvent,view) {
$('#myCalendar').fullcalendar('select', date);
}
});
Note you will also need to fire the 'unselect' method on your next callback (or dayClick).
Why not use selectAllow?
Start by converting the start and end times to seconds. Compare that to the number of seconds in a day.
Working Solution Without Using Moment.js:
selectAllow: function (e) {
if (e.end.getTime() / 1000 - e.start.getTime() / 1000 <= 86400) {
return true;
}
}
This configuration setting worked for me on FullCalendar v5:
selectAllow: function(selectionInfo) {
let startDate = selectionInfo.start;
let endDate = selectionInfo.end;
endDate.setSeconds(endDate.getSeconds() - 1); // allow full day selection
if (startDate.getDate() === endDate.getDate()) {
return true;
} else {
return false;
}
}
simply :
selectAllow: function (selectInfo) {
return selectInfo.end.diff(selectInfo.start, 'days') == 1;
}
For me using the selectAllow option like this worked
selectAllow: function(selectionInfo) {
// Don't allow creation of events over more than 1 day
return moment(selectionInfo.start).utcOffset(false).isSame(moment(selectionInfo.end).subtract(1, 'second').utcOffset(false), 'day');
},
I used utcOffset(false) because for whatever reason it doesn't work reliably without it and I used subtract(1, 'second') because the end date is inclusive, so without it you can't select the end of the day
This will be executed only when the user selects a day
// ...
select: function(start, end){
if(moment(start._d).add(1, 'days').format('YYYY-MM-DD')==moment(end._d).format('YYYY-MM-DD')){
// just select one day
}
},
// ...
I could do this using validRange:
https://fullcalendar.io/docs/validRange
Not at this time: the range of selectable days can not be customized without modifying the source.
The ASP.NET calendar always displays 6 weeks of dates in a 7x6 grid. My problem is that the first day of the target month does not necessarily appear in the first row... in some cases, the entire first row displays dates from the previous month. In other cases, the entire last row displays dates from the next row.
Is there a reliable way to query the calendar object to determine the 42-day range that would be rendered for a specific month/year?
For example, consider June 2008 and Feb 2009:
Notice that the first week contains ONLY dates from prior month http://img371.imageshack.us/img371/2290/datesmq5.png
I assume that the calendar tries to avoid bunching all of the "other month" dates at either the top or bottom of the grid, and therefore puts the first of the target month on the 2nd row. I am looking for an easy way to determine that the displayed range for June 2008 is May 25 - July 5, for instance.
Looking at the public members exposed by the ASP.NET Calendar control I do not believe that this information is something that you can just get from the calendar control.
You have a few options as "workarounds" to this though, although not nice....but they would work.
You could manually calculate the first week values
You can handle the "day render" event to handle the binding of the individual days, and record min/max values.
Granted neither is elegant, but AFAIK it is the only real option
Edit
After discussion in the comments, another option is a modified version of my second option above. Basically the first time Day Render is called, get the block of data for the next 42 days, then you can simply search the list for the proper day value to display on future calls to DayRender, avoiding a DB hit for each day. Doing this is another "non-elegant" solution, but it works, and reduces a bit of load on the DB, but introduces some overhead on the application side.
It will be important here to define well structured page level properties to hold the items during the binding events, but to ensure that if a month changed, etc that it wasn't loaded incorrectly etc.
I wrote a couple of methods to help with this. Just pass in Calendar.VisibleDate:
public static DateTime GetFirstDateOfMonth(DateTime date)
{
return new DateTime(date.Year, date.Month, 1);
}
public static DateTime GetFirstDisplayedDate(DateTime date)
{
date = GetFirstDateOfMonth(date);
return date.DayOfWeek == DayOfWeek.Sunday ? date.AddDays(-7) : date.AddDays((int)date.DayOfWeek * -1);
}
public static List<DateTime> GetDisplayedDates(DateTime date)
{
date = GetFirstDisplayedDate(date);
List<DateTime> dates = new List<DateTime>();
for (int i = 0; i < 42; i++)
{
dates.Add(date.AddDays(i));
}
return dates;
}
I've just been looking into this myself, and got directed to here. I'm personally tempted to go with option two, because the alternative is messy. Ronnie's version is nice, but unfortunately doesn't take into account cultures with different FirstDayOfWeeks.
Using Reflector, we can see how it's done internally:
...
DateTime visibleDate = this.EffectiveVisibleDate();
DateTime firstDay = this.FirstCalendarDay(visibleDate);
...
private System.Globalization.Calendar threadCalendar =
DateTimeFormatInfo.CurrentInfo.Calendar;
private DateTime EffectiveVisibleDate()
{
DateTime visibleDate = this.VisibleDate;
if (visibleDate.Equals(DateTime.MinValue))
{
visibleDate = this.TodaysDate;
}
if (this.IsMinSupportedYearMonth(visibleDate))
{
return this.minSupportedDate;
}
return this.threadCalendar.AddDays(visibleDate,
-(this.threadCalendar.GetDayOfMonth(visibleDate) - 1));
}
private DateTime FirstCalendarDay(DateTime visibleDate)
{
DateTime date = visibleDate;
if (this.IsMinSupportedYearMonth(date))
{
return date;
}
int num = ((int)
this.threadCalendar.GetDayOfWeek(date)) - this.NumericFirstDayOfWeek();
if (num <= 0)
{
num += 7;
}
return this.threadCalendar.AddDays(date, -num);
}
private int NumericFirstDayOfWeek()
{
if (this.FirstDayOfWeek != FirstDayOfWeek.Default)
{
return (int) this.FirstDayOfWeek;
}
return (int) DateTimeFormatInfo.CurrentInfo.FirstDayOfWeek;
}
private bool IsMinSupportedYearMonth(DateTime date)
{
return this.IsTheSameYearMonth(this.minSupportedDate, date);
}
private bool IsTheSameYearMonth(DateTime date1, DateTime date2)
{
return (((this.threadCalendar.GetEra(date1) ==
this.threadCalendar.GetEra(date2)) &&
(this.threadCalendar.GetYear(date1) ==
this.threadCalendar.GetYear(date2))) &&
(this.threadCalendar.GetMonth(date1) ==
this.threadCalendar.GetMonth(date2)));
}
Sadly, the functionality is already there, we just can't get at it!
Mitchel,
Worked perfectly, thank you.
Started with a public variable
bool m_FirstDay = false
in the day_render function
if(m_FirstDay == false)
{
DateTime firstDate;
DateTime lastDate;
firstDate = e.Day.Date;
lastDate = firstDate.AddDays(41);
m_FirstDay = true;
}
I then had the visible date range of the asp.net calendar control. Thanks again.
see this one.
