How to use
In your web page:
<script src="path/to/jquery.js" type="text/javascript"></script> <script src="path/to/timer.jquery.js"></script> <script> (function($) { //start a timer $("#div-id").timer(); }()); </script> Usage Instructions
Start a timer from 100 seconds (1:40)
$("#div-id").timer({ seconds: 100 }); 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. You can use this to sync current state with the backend by initiating a ajax request at regular intervals.
//start a timer & execute a function every 2 minutes $('#div-id').timer({ duration: '2m', callback: function() { alert('Why, Hello there'); //you could have a ajax call here instead }, repeat: true //repeatedly calls the callback you specify }); 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
