So one common problem is with the Date Object. The problem only seems to exist when you are passing in a date into a date object such as:
var d = new Date("2014-02-24"); alert(d);
If you were to do that in Internet Explorer then you would get NaN. The issue is that Internet Explorer 8 doesn’t support the date format of “yyyy-mm-dd”. I have no idea why that would be. Also, I don’t have a list of all possible formats but one you can use is:
var d = new Date("02/24/2014"); // "mm/dd/yyyy"
var d = new Date(2011, 01, 24); // yyyy, mm-1, dd
If you keep that in mind, you should be okay.
