jquery timer implementation

Question

All,

Is there a jQuery timer which can start a timer for 20 minutes and display time elapsed? Please point me to a small code for it.

var austDay = new getTime();
austDay = new getSeconds(austDay);
var duration = 1200;
duration +=  austDay;

Thanks

Not sure about a jQuery solution, but it's quite simple to do anyway:

var elapsed = 0;
var interval;
var total = 60 * 20; // 20 mins in seconds

function showElapsedTime()
{
    if(elapsed < total)
    {
        elapsed += 1;

        // If you want you can convert the seconds elapsed to minutes and seconds
        // here before you display them

        $('#elapsed').html(elapsed);
    }
    else
    {
        clearInterval(interval);
        alert('Done');
    }
}

$(function(){
    interval = setInterval(showElapsedTime, 1000);
});

Where #elapsed is a div or span that you want to show the elapse time in.

There are quite a few timer plugins, but they are all just abstractions of setTimeout and setInterval anyway, and I'm not sure they're really much simpler to use.

Here is an example of slighly different behaviour. You can change it to suite your needs.

   1. $("#start").click(function() {
   2.  $("#example_2").everyTime(1000, 'timer2', function(i) {
   3.   $(this).text(i);
   4.  }, 15);
   5. });
   6. $("#stop").click(function() {
   7.  $("#example_2").stopTime('timer2');
   8. });
