how to add days to date variable on every ng-repeat loop in angularjs

Question

I have set date variable in "ng-init" directive and i want to add days to this date variable on every ng-repeat loop like below:

<table>
  <tr ng-repeat="n in myArr" ng-init="myDate=('07/25/2017'|date:addDays($index))">
    <td ng-bind="myDate"></td>
  </tr>
</table

You can instantiate your first date in the controler like this :

$scope.firstDate = new Date('07/25/2017');

And add days to it in the ngRepeat like this :

<tr ng-repeat="n in myArr" ng-init="myDate=(firstDate.setDate(firstDate.getDate() + 1)|date)">

And if you want your date with the format mm/dd/yyyy, you need to add at the end of your ngInit :'M/d/yyyy', like this (you can take a look at the doc for more information about date format) :

<tr ng-repeat="n in myArr" ng-init="myDate=(firstDate.setDate(firstDate.getDate() + 1)|date:'M/d/yyyy')">

But if you have other things to do with dates I think it could be a good idea to take a look at moment.js

var app = angular.module('plunker', []);

app.controller('MainCtrl', function($scope) {
  $scope.firstDate = new Date('07/25/2017');
  $scope.myArr = [1, 2, 3, 4, 5];
});

<table ng-app="plunker" ng-controller="MainCtrl">
  <tr ng-repeat="n in myArr" ng-init="myDate=(firstDate.setDate(firstDate.getDate() + 1)|date)">
    <td ng-bind="myDate"></td>
  </tr>
