toLocaleDateString() in IE returns a 14 character string - is it a bug

Please look at http://jsbin.com/mehowehase/1/edit?html,js,console

var dt = new Date();
var x = dt.toLocaleDateString();
console.log("length : "+x.length);
var arr = x.split("/");
console.log("month : "+parseInt(arr[0],10));

In the above the length of x is 14 in IE but 9 in other browsers. Also the month value comes as NaN. Is this a bug in IE. How can we fix this.

This is a bug in IE11. You can find temporarily solution for this issue here

Basically you need to replace U+200E (LEFT-TO-RIGHT MARK).

console.log((new Date()).toLocaleDateString().replace(/\u200E/g, ''));

It is not a bug. IE's toLocaleDateString method returns a unicode string, and your code isn't expecting one. For example, the first character in IE (for me and my locale (en-US)) is 8206, which is the left-to-right mark character, which is also why your parseInt is failing. The entire sequence is

8206,49,49,8206,47,8206,51,8206,47,8206,50,48,49,53

which is 14 characters long and looks like "11/3/2015"

Why aren't you doing this:

var dt=new Date();
var day=dt.day;
var month=dt.month;
var year=dt.year;

Solved it like this

var day = arr[1];
var month = arr[0];
var year = arr[2];
if(isNaN(month)){
   var curr = "";
   for (var i = 0; i < month['length']; i++) {
      if(!isNaN(month.charAt(i)))
         curr += parseInt(month.charAt(i));
   }
   month = curr;
}
console.log("month: "+parseInt(month,10));

For me, on Chrome 42.0 the string output of toLocaleDateString is "11/3/2015". For Internet Explorer 11.0.9, it is "Tuesday, November 03, 2015". You'll have to change your parsing to read the format that Internet Explorer outputs, it's has all of the information you need, just in a different format.
