What is Event Propagation?
During the capturing phase, the event traverses from the outermost parent element down to the target element, allowing ancestor elements to capture the event along the way.
Once the event reaches the target element, the target phase begins, where event handlers attached directly to the target element are executed.
After the target phase, the event enters the bubbling phase, where it travels upward through the parent elements, triggering their respective event handlers.
To visualize this concept, we can represent it using a diagram:
This diagram illustrates the event propagation flow. The event starts from the topmost parent element, goes through the capturing phase, reaches the target element, and then proceeds to the bubbling phase, propagating it up to the parent elements.
By understanding event propagation, we can handle events at different levels of the DOM hierarchy, providing flexibility and control in event handling.
What is Event Bubbling?
When an event gets triggered within the nested set of HTML elements, this event bubbles up from that element to the outermost element of the nested HTML elements, this process is called event bubbling. During this process, event listeners attached to those elements which were involved in the bubbling process of that event also get triggered like a ripple in a pond.
