Event handling is a fundamental aspect of JavaScript, but it’s crucial to consider accessibility when implementing it. In this article, we’ll explore the concepts of event bubbling and capturing, and how to ensure your event handling practices are inclusive for all users.
Understanding Event Bubbling and Capturing
Event bubbling and capturing are two different ways in which events propagate through the DOM (Document Object Model).
Event Bubbling: When an event occurs on an element, it first triggers the event handler on that element, then it “bubbles up” to the parent elements, triggering their event handlers as well, until it reaches the top of the DOM tree.
Event Capturing: In this approach, the event is first captured by the outermost element in the DOM tree, and then it “trickles down” to the target element, triggering event handlers along the way.
Accessibility Considerations
While both event bubbling and capturing have their use cases, it’s important to consider accessibility when implementing them. Here are some key points to keep…
