Javascript Converting IETF Date to ISO8601 Format

I am using this awesome jQuery calendar plugin

http://arshaw.com/fullcalendar/

One of the options for clicking on a date is a callback function to return the date that is clicked on.

I believe it only returns the date in this format IETF format - Wed, 18 Oct 2009 13:00:00 EST

I however, need it to 开发者_如何学JAVAbe in ISO861 format to post the data. I can't seem to find anything on it in google. I am trying to convert it in Javascript. If not, then conversion can take place in the Java backend. Help is appreciated

From the fine manual:

date holds a Date object for the current day.

Emphasis mine.

I'd guess that the IETF format you're seeing is just the default stringification of the Date object. The Date class has getYear(), getMonth(), and getDate() methods so you can easily produce an ISO-8601 date string if you're careful with the zero-padding of course.

Since dayClick gives you a Javascript Date object already, you can format it as an 8601 formatted date string using this function from the Mozilla site.

it returns a regular javascript date object. you can use the fullcalendar formatDate utility function with it like this:

$.fullCalendar.formatDate(date, 'u');

you can use the formatDate function belong on your Date object dayClick!

function getGMTOffset(localDate) {
    var positive = (localDate.getTimezoneOffset() > 0);
    var aoff = Math.abs(localDate.getTimezoneOffset());
    var hours = Math.floor(aoff / 60);
    var mins = aoff % 60;
    var offsetTz = padzero_(hours) + ':' + padzero_(mins);
    // getTimezoneOffset() method returns difference between (GMT) and local time, in minutes.
    // example, If your time zone is GMT+2, -120 will be returned.
    // This is why we are inverting sign
    if (!positive) {
      return '+' + offsetTz;
    }
    return '-' + offsetTz;
}

      n = '0' + n;
