campare two dates in Javascript

The Date object is also used to compare two dates.

The following example compares today's date with the 14th January 2011:

/* var myDate=new Date(); myDate.setFullYear(2011,0,14); var today = new Date(); if (myDate>today)   {   alert("Today is before 14th January 2011");   } else   {   alert("Today is after 14th January 2011");   }

*/
