Error throwed is Microsoft JScript runtime error: Object doesn't support this property or method

I m using jQuery 1.3.2 in my page .

Whats wrong with this? Please help

Answer 1

There is no addDays() method - you need to use setDate():

now3.setDate(now3.getDate() - 4);

See the Date object documentation for more information.
