Date issue in ie8

I was left stunned when I encountered this wierd IE8 issue. My flow involved taking input from the user via a calender and convert that input into date. I used a datepicker which returned me date string in the format yyyy-mm-dd.

I took the values selected by user and pass it ot the Date constructor in javascirpt and it worked in FF, Chrome, IE8+. But as soon as i tried the same in IE8 it Bombed and left me wondering why?

Here's the code:

var dt=new Date("2013-05-28");

What really happend?

MSDN documentation says:

ISO Date Format is not supported in Internet Explorer 8 standards mode and Quirks mode.

ISO format is YYYY-MM-DDTHH:mm:ss.sssZ

Solution

Solution 1: To allow IE8 to be able to construct date we need to replace all - with /.

var d="2013-05-28";
d=d.replace(/-/g,"/");
var dt=new Date(d);

Solution 2: We can also do something like this.

var d="2013-05-28";
var dt=new Date();
dt.setYear(d.substring(0,4));
dt.setMonth(d.substring(5,7),d.substring(8,10));
