It’s replacement, .on(), DOES NOT bind to future elements by default.

The following explains how to bind future elements using .on().

You want to loop through a collection of DOM objects, so you use .each().

But what if you want to have a delay between effects on the current item?

In short – don’t use .each() for looping – and don’t use setTimeout for the delay.

We’re going to call items by index instead, optionally using a clever way to add a delay.

Handling multiple timers with JavaScript’s setInterval and jQuery

For a recent project I needed to create a slideshow with auto play capability. To achieve this I used JavaScript’s setInterval to rotate the slides every 15 seconds.

window.clearInterval(intervalId);

All well and good if you only have one timer on a page.
