"Number Expected" Error in IE 11 with .toISOString()

I'm getting the error "Number expected" at the line:

new Date($('#itemOpenDate').val()).toISOString()

Open in new window



where $('#itemOpenDate').val() is a string representing a date, e.g. "8/11/2016"

No problems in the latest version of Chrome, Firefox, and Safari. Should be supported in IE11 per the documentation. Am I missing something?

go over, don't fight with IE, use this :
var arr = $('#itemOpenDate').val().split("/");
new Date(arr[2], arr[0]*1-1, arr[1]).toISOString();

Open in new window

That should work, but IE 11 gives me NaN for arr[0] * 1 - 1. Other browsers return the expected...

I've narrowed it down to how I'm populating the form field. See the below code. For line 43, the following works in IE11:

$('#itemOpenDate').val(new Date("8/2/2016").toDateString());

Open in new window


but I want the locale string format "8/2/2016", and the following breaks (in IE11 only):

$('#itemOpenDate').val(new Date("8/2/2016").toLocaleString());

Open in new window


Any ideas?

I got it to work by using momentjs in line 43, instead of
toLocaleString()

Open in new window

:

$('#itemOpenDate').val(moment("8/2/2016").format("L"));

Open in new window
