Code for validating date in javascript

When setting a date, without specifying the time zone, Java Script will use the browser's time zone.When getting a date, without specifying the time zone, the result is converted to the browser's time zone.If you are passing in a string to the date constructor, you must pass in a standardised string to get a reliable result.Specifically, "The string should be in a format recognized by the Date.parse() method".Search the page for "parsedate" and you'll find: $.datepicker.parse Date( format, value, settings ) - Extract a date from a string value with a specified format.(More info re specifying date formats is found at Date) In the above example, you wouldn't see the alert message since '01/03/2012' is a calendar-valid date in the specified format. Inspired by Borgar's approach I have made sure that the code not only validates the date, but actually makes sure the date is a real date, meaning that dates like 31/09/2011 and 29/02/2011 are not allowed.In a nutshell, Array objects created within one iframe do not share

Even if you don't want to use the datepicker widget on your page as a UI element, you can always add its library to your page and then call the validator method, passing the value you want to validate into it.To make life even easier, it takes a string as input, not a Java Script Date object.See: It's not listed as a method, but it is there-- as a utility function.You don't need to do that when using HTML 5 type="date" attribute (the format then will be forced to be YYYY-MM-DD).options can be either a date string in the format of YYYY-MM-DD or a Date object.
