jQuery Timer

Download the jQuery timer plugin and put it in a SCRIPT tag in your HTML page after jQuery itself. 

$('#divId').timer(); //Same as $('#divId').timer('start')

$('#divId').timer({
    seconds: 100 //Specify start time in seconds
});

$('#divId').timer('pause');

$('#divId').timer('resume');

$('#divId').timer('remove');

$('#divId').data('seconds');

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

//start a timer & execute a function every 2 minutes
$('#divId').timer({
    duration: '2m',
    callback: function() {
        alert('Why, Hello there');
    },
    repeat: true //repeatedly calls the callback you specify
});

//start a timer & execute a function every 30 seconds and then reset the timer at the end of 30 seconds.
$('#divId').timer({
    duration: '30s',
    callback: function() {
        console.log('Timer will reset!');
    },
    repeat: true, //repeatedly call the callback
    reset: true //optionally reset the timer to 0
});
