Jquery prevents event bubbles

I wrote a small effect for my friend. After clicking the label, the label will change color and add a cross image. Then, I click the label to restore it to its original state. For details, click the result below.

It is not difficult, but it mainly records the blocking event bubbles.

Because a click event is added to the DIV, And the IMG inside the DIV also adds a click event, when you click IMG, The Click Event on the IMG is triggered first, and then the click event on the DIV is triggered, this is event bubbling.

In jquery, we can easily block it.

As follows:

1Event. stoppropagation ();

In this way, clicking IMG will no longer trigger the DIV click event.
