<script src="path/to/timer.jquery.js"></script>
<script>
(function($) {

  //start a timer
  $("#div-id").timer();

}());
</script>

Usage

To start a timer with options:

$("#div-id").timer(options);

Options for timer:

$("#div-id").timer({
	seconds:	{Int},		// The number of seconds to start the timer from
	duration: 	{String},	// The time to countdown from. `seconds` and `duration` are mutually exclusive
	callback: 	{Function},	// If duration is set, this function is called after `duration` has elapsed
	repeat: 	{Bool},		// If duration is set, `callback` will be called repeatedly
	format:		{String},	// Format to show time in
	editable:	{Bool}		// If click and edit time is enabled
});

Methods available on an initialized timer:

//pause an existing timer
$("#div-id").timer('pause');

//resume a paused timer
$("#div-id").timer('resume');

//remove an existing timer
$("#div-id").timer('remove');  //leaves the display intact

//get elapsed time in seconds
$("#div-id").data('seconds');

Timed Events

Start a timer and execute a function after a certain duration. You can use this to simulate a timed event.

//start a timer & execute a function in 5 minutes & 30 seconds
$('#div-id').timer({
	duration: '5m30s',
	callback: function() {
		alert('Time up!');
	}
});

Start a timer and execute a function repeatedly at a certain duration.

//start a timer & execute a function every 2 minutes
$('#div-id').timer({
	duration: '2m',
	callback: function() {
		console.log('Why, Hello there');	//you could have a ajax call here instead
	},
	repeat: true //repeatedly calls the callback you specify
});

Start a timer and execute a function repeatedly at a certain duration and then reset the timer.

//start a timer & execute a function every 2 minutes
$('#div-id').timer({
	duration: '2m',
	callback: function() {
		$('#div-id').timer('reset');
	},
	repeat: true //repeatedly calls the callback you specify
});

Timer state

You can get the current state of timer by querying the state property on it’s data object

$('#div-id').data('state'); 	// running | paused | stopped
Duration Syntax

When you initialize a timer with the duration and callback parameters, the timer plugin executes the callback function at the set duration. The syntax for specifying the duration is verbose. h for hours. m for minutes and s for seconds. Here are some examples:

'3h15m'		// 3 hours, 15 minutes
'15m'		// 15 minutes
'30s'		// 30 seconds
'2m30s'		// 2 minutes 30 seconds
'2h15m30s'	// 2 hours 15 minutes and 30 seconds
Format Syntax

By default the timer displays the biggest whole unit. Examples:

  • seconds: 50 will show as 50 sec
  • seconds: 63 will show as 1:03 min
  • seconds: 3663 will show as 1:01:03

If you want to customize the format in which the timer displays time, use the format option. Available formats the timer understands are:

Format Description Example
%h Non-zero padded Hours %h hours gives 3 hours
%m Non-zero padded Minutes unless number of minutes is greater than 60 %h:%m minutes gives 0:6 minutes or 1:06 minutes
%g Non-zero padded Total Minutes Irrelative to hours %G minutes gives 75 minutes or 6 minutes
%s Non-zero padded Seconds unless number of seconds is greater than 60 %h:%m:%s gives 0:0:6 or 0:1:06 or 1:01:06
%t Non-zero padded Total Seconds Irrelative to minutes and hours %t gives 3660 or ‘9’
%H Zero padded Hours %H hours gives 03 hours
%M Zero padded Minutes %H:%M minutes gives 00:06 minutes
%G Zero padded Total Minutes Irrelative to hours %G minutes gives 75 minutes
%S Zero padded Seconds %H:%M:%S gives 00:00:06
%T Zero padded Total Seconds Irrelative to minutes and hours %T gives 3660

Countdown

You can use the jQuery timer plugin for countdown as well.

$('#timerDiv').timer({
    countdown: true,
    duration: '3m40s',    	// This will start the countdown from 3 mins 40 seconds
    callback: function() {	// This will execute after the duration has elapsed
    	console.log('Time up!');
    }
});
