When clicking on the <b>div</b> element, it will alert that the div element was clicked. When clicking on the <b>p</b> element, it will return both the p and the div element, since the p element is inside the div element. But when clicking on the <b>span</b> element, it will only return itself, and not the p and the div element (even though its inside these elements). The event.stopPropagation() stops the click event from bubbling to the parent elements. </p> <p><b>Tip:</b> Try to remove the event.stopPropagation() line, and click on the span element again (the click event will now bubble up to parent elements).</p> <footer>简单教程，简单编程<br/>Copyright © 简单教程 www.twle.cn</footer>
