如何将日期格式从dd / mm / yyyy更改为MM / dd / yyyy，其中日期已从字符串转换？

Question

I am getting date from a API which is in string format, I converted that string to date but unable to change it's format. Currently I got string like this -> '20/11/2016' I want to convert this & should look like this -> 11/20/2016 & then only I can display this in html page using html 5 date input type

    <input type='date' ng-model='myDate'>

   myApp.controller('myCtrl',['$scope','$filter'],
   function ($scope,$filter)
   {
    //consider this string comes from api...
   var stringDate='20/11/2016';
   var convertedDate=new Date(stringDate);
   $scope.myDate=$filter('date')(convertedDate,'MM/dd/yyyy');
   });

Answer 1

var stringDate1=this.dStartDate;
var splitDate1 = stringDate1.split('-');
var year1  = splitDate1[0];
var month1 = splitDate1[1];
var day1 = splitDate1[2];
this.dStartDate = month1+"-"+day1+"-"+year1;
console.log("date"+this.dStartDate);

Answer 2

Using momentjs

var convertedDate = moment('20/11/2016', 'dd/MM/yyyy');

Using vanilla javascript

var dateArray = '20/11/2016'.split('/');
var convertedDate = new Date(dateArray[1]+'-'+dateArray[0]+'-'+dateArray[2]);

Probably this is not the best implementation, but it works!

Answer 3

remove 'new' so

var stringDate='20/11/2016';
var convertedDate=new Date(stringDate);

should be

var stringDate='20/11/2016';
var convertedDate=Date(stringDate);

Answer 4

First of all you can not give stringDate directly as input to Date object as it is not a valid Date string.

Revised code:

var stringDate='20/11/2016';
var splitDate = stringDate.split('/');
var convertedDate=new Date(splitDate[2], splitDate[1]-1, splitDate[0]);
console.log(convertedDate.toLocaleDateString("en-US"));
$scope.myDate = convertedDate.toLocaleDateString("en-US");

Here using en-US locale returns 11/20/2016 format. You can find more about toLocale conversion here .

Answer 5

Here you go:

  var stringDate='20/11/2016';
  $scope.myDate=$filter('date')(stringDate, 'MM/dd/yyyy');

Answer 6

You can split and then pass to date object. After that using Date functions reform the date.

var dateArray = '31/12/2016'.split('/');
var convertedDate = new Date(dateArray[1]+'-'+dateArray[0]+' '+dateArray[2]);
