Angularjs next and previous day, year, month

Question

Using the Angular date $filter date, I can get the current day, year and month .

But how can I get the next and previous day, year, month ?

This is the code I wrote, but I don’t know where to start with

 $scope.month = $filter('date')(date, 'MMMM');//December-November like $scope.day = $filter('date')(date, 'dd'); //01-31 like $scope.year = $filter('date')(date,'yyyy');//2014 like $scope.nextYear = Number($scope.year) + 1; $scope.prevYear = Number($scope.year) - 1; $scope.nextDay = ? etc... 

Do you have any ideas?

You can do it like this, angular date $ filter does not offer you an easier way to do this, it just formats the date in the user-desired format.

day

 var myDate = new Date(); var previousDay = new Date(myDate); previousDay.setDate(myDate.getDate()-1); var nextDay = new Date(myDate); nextDay.setDate(myDate.getDate()+1); 

Month

 var previousMonth = new Date(myDate); previousMonth.setMonth(myDate.getMonth()-1); var nextMonth = new Date(myDate); nextMonth.setMonth(myDate.getMonth()+1); 

Year:

 var previousYear = new Date(myDate); previousYear.setYear(myDate.getFullYear()-1); var nextYear = new Date(myDate); nextYear.setYear(myDate.getFullYear()+1); $scope.month = $filter('date')(myDate, 'MMMM');//December-November like $scope.day = $filter('date')(myDate, 'dd'); //01-31 like $scope.year = $filter('date')(myDate,'yyyy');//2014 like $scope.nextDay = $filter('date')(nexyDay, 'dd'); $scope.prevDay = $filter('date')(previousDay, 'dd'); $scope.nextMonth = $filter('date')(nextMonth, 'MMMM') $scope.prevMonth = $filter('date')(previousMonth, 'MMMM') $scope.nextYear = $filter('date')(nextYear,'yyyy'); $scope.prevYear = $filter('date')(previousYear,'yyyy'); 

If you are going to do this a lot, I suggest you create a service to implement this logic.
