How to add year/months/day to a current date using angularJS -

i new angularjs , how add together year current date.

let's can user dob , want add together year+1.

i have tried using,

$scope.userdob = $rootscope.user.dob; $scope.userdob.add(1,'years');

but it's not working.

can help me know logic illustration ?

tia..,

it looks $rootscope.user.dob instance of moment moment.js library. think main problem angular's alter detection cannot observe when mutate instance. because instance remains same internal underlying date value change. i'd suggest:

$scope.userdob = $rootscope.user.dob.clone().add(1,'years').valueof();

that way angular regular javascript date object instead of moment instance , it's alter detection work correctly.

fyi accomplish same standard javascript date instance can do:

var userdob = new date(); userdob.setyear(userdob.getfullyear() + 1)

to advance year 1.
