Making Live Clock javascript

Question

does anyone know how to make live javascript time running..

i have this php code

    $expiredate = date(\'d m Y G:i:s\', $rdate1);
    $f_ex_date =          


        

Answer 1

Here's how to do it. Working Demo.

First, at the top of your HTML document:

.datetime {
    color: #C11B17;
    font-family:arial;
    font-size: 16px;
}

We do this so we can clean up our HTML code a little bit:

$rdate1 = 1240550032; // Fri, 24 Apr 2009 05:13:52 GMT
$expiredate = date('d m Y G:i:s', $rdate1);
$time = $rdate1 - time();
$days = floor($time/86400);
$hours = floor(($time-($days*86400))/3600);
$mins = floor(($time-($days*86400)-($hours*3600))/60);
$secs = floor($time-($days*86400)-($hours*3600)-($mins*60));

printf("
    Your account is going to expire in
    %s Days
    %s Hours
    %s Minutes
    %s Seconds
", $days, $hours, $mins, $secs);

I'm not quite sure where that middle step you were taking for came from, but the code above gets me the difference in time between $rdate1 (presumably a unix timestamp) and time().

Finally, we can do something like this with Javascript to update the time once the page loads:

addEvent(window, 'load', function() {
    var eDays = document.getElementById('days');
    var eHours = document.getElementById('hours');
    var eMinutes = document.getElementById('minutes');
    var eSeconds = document.getElementById('seconds');
    var timer;
    timer = setInterval(function() {
        var vDays = parseInt(eDays.innerHTML, 10);
        var vHours = parseInt(eHours.innerHTML, 10);
        var vMinutes = parseInt(eMinutes.innerHTML, 10);
        var vSeconds = parseInt(eSeconds.innerHTML, 10);

        vSeconds--;
        if(vSeconds < 0) {
            vSeconds = 59;
            vMinutes--;
            if(vMinutes < 0) {
                vMinutes = 59;
                vHours--;
                if(vHours < 0) {
                    vHours = 23;
                    vDays--;
                }
            }
        } else {
            if(vSeconds == 0 &&
               vMinutes == 0 &&
               vHours == 0 &&
               vDays == 0) {
                clearInterval(timer);
            }
        }
        eSeconds.innerHTML = vSeconds;
        eMinutes.innerHTML = vMinutes;
        eHours.innerHTML = vHours;
        eDays.innerHTML = vDays;
    }, 1000);
});


function addEvent( obj, type, fn ) {
  if ( obj.attachEvent ) {
    obj['e'+type+fn] = fn;
    obj[type+fn] = function(){obj['e'+type+fn]( window.event );}
    obj.attachEvent( 'on'+type, obj[type+fn] );
  } else
    obj.addEventListener( type, fn, false );
}
