Timer Based Animations using jQuery

Abstract: In this article, we will explore how to create timer based animations using jQuery.

There are two functions built into JavaScript that allow you to implement a time based delay in your code – setTimeOut() and setInterval(). The difference between the two is that setTimeout performs an action only once after the specified time period elapses, however setInterval keeps repeating the action.

In this article, we’ll see how a <div> can be hidden once the user clicks on it. We will also see how to auto collapse the <div> if the user does not click on it within 10 seconds. Since we need to perform the action only once, we will use setTimeOut() to create a Time Bound Animation.


Create a new file ‘TimeBoundAnimations.html’. Use the following Div:

<div id="divautofade">
    Watch this Div auto close after 10 seconds.<br /><br />
    Alternatively, Click on the Div to close.

Let’s see the code which autocollapses our Div in 10 seconds if the user does not manually hide it by clicking on it.

$("#divautofade").on("click", function () {
    if (timer)

var timer = setTimeout(function () {
}, 10000);

As you can see, we have used setTimeout to add a delay, and run the code at a specified time interval of 10 seconds. The code hides the Div after 10 seconds by calling slideUp() on the Div.

We have also attached a click handler to the Div, which hides the Div using slideUp() when it is clicked upon. If you observe, setTimeout returns an ID timer which we pass to clearTimeout to cancel the running of the timeout. This is done to avoid slideUp from being triggered if the div is already clicked in that 10 second duration. If the timeout has already run, clearing it won’t do anything.

$("#divautofade").on("click", function () {
    if (timer)

Save and view the file in your browser. Click on the Div to collapse it. Now refresh the page and wait for 10 seconds. The div will auto collapse.

Using this technique, you can build some cool notification widgets in your website!

Using delay() and stop()

The same requirement can be achieved using a built-in function of jQuery - delay(). Let us see how.

Create a new file ’1-TimeBoundAnimations.html’. Our markup remains the same. Use the following code:

$("#divautofade").on('click', function () {

As you can see, we have used chaining to elegantly achieve what we did with setInterval. The click hides the div using slideup(). We have used stop(true) to clear the animation queue so that delay(10000).slideUp('100') does not get fired if the div has already been closed by clicking on it.

Using delay() we set a timer to delay the slideup() in the queue by 10 seconds.

That’s it. Save and view the page in your browser and you have the same effect we achieved using setInterval().
