Answer 2

You could use this solution (worked in my case) -

Firstly, use Moment.js in your code, include it in your project. Now, The time string that you are getting here var str = "29-1-2016"; and along with moment.js use the below code and you're good to go -

var str = "29-1-2016";
var time = moment(str).toISOString();
\\ This variable time is now converted into ISO string

Answer 3

convert your date using toISOString

var mydate="2017-04-24"
var IsDate=new Date(mydate).toISOString();
console.log('my iso date',IsDate);
