Convert string to javascript date

Question

I have a string that I retrieve from a JSON object and I am trying to cast that to a javascript date variable as given below but its returning an Invalid date all the time. Any reasons why?

jsonObj["dateValue"]; //has a value: 2016-11-04T08:08:42.5780021+00:00
var dateValue = new Date(jsonObj["dateValue"]); // returns invalid date??

JsFiddle

do a typeof of jsonObj["dateValue"], what is that returning? — aliasav

if you do a new Date("2016-11-04T08:08:42.5780021+00:00") it shall return a valid date object, provided that its a string — aliasav

Please create a snippet that reproduces the problem, because the code you posted does not give this error. — trincot

You have the jsonObj as an array not an object. The first value in the array is your actual object.

try:

 var dateValue = new Date(jsonObj[0]["dateValue"]);

Or simplify your jsonObj value by making it the object, not a wrapping array.

Your jsonObj is an array - you should thus take the first item

var jsonObj = [{
dateValue : "2016-11-04T08:08:42.5780021+00:00"
}];

var dateValue = new Date(jsonObj[0]["dateValue"]);
console.log(dateValue);
