Jquery Countdown Showing NaN in Safari, Works fine in Chrome / Firefox

Question

I am creating a penny auction site and I have several auctions on the home page. Each auction gets its own timer based on a date from the mysql date format, which is in format 'Y-m-d H:i:s'.

The code works fine and the timers all start counting down perfectly on Firefox and Chrome, but in Safari the number shows NaN:NaN:NaN

Here's my function, its using the jquery countdown plugin by Keith Wood:

function updateTimers() {
        $( ".il-timer" ).each(function( index ) {

            var timer = $(this);
           var end_date = $(timer).attr('data-end-date');
           var auction_id = $(timer).attr('data-auction-id');

           var end = new Date(Date.parse(end_date,"yyyy-mm-dd hh:mm:ss"));

          $('#auction_listing_timer_'+auction_id).countdown({until: end, format: 'HMS', compact: true, description: ''});

          //Do it every 10 seconds...
            setTimeout(function(){

                updateTimers();

            }, 10000);

        });
    };

Answer 1

A few things:

• The Date.parse function does not take a second parameter. The value "yyyy-mm-dd hh:mm:ss" you're passing is being ignored.

• Date parsing in JavaScript is implementation dependent. Firefox chooses not to parse values in that particular format.

• new Date(Date.parse(...)) is redundant. You can just pass the string to the date constructor.

• A quick fix would be to replace the dashes with slashes before parsing:

  var end = new Date(end_date.replace(/-/g, '/'));
  

• A better approach would be to use a library like moment.js, so you can control the format used for parsing:

  var end = moment(end_date, 'YYYY-MM-DD HH:mm:ss').toDate();
