Event Listening on Dynamically Created Elements without jQuery
When working with external pages, adding event listeners to dynamically generated elements can prove challenging. Delegating event handling is crucial in such scenarios.
One approach is to use the event.target property to check if the clicked or triggered element is of the desired type. Here's an example:
<code class="javascript">document.querySelector('body').addEventListener('click', function(event) {
if (event.target.tagName.toLowerCase() === 'li') {
// Execute desired action on encountered 'li' elements
}
});</code>
Note: This approach assumes that your desired elements are within the
element. Adjust the selector accordingly if they're nested within other containers.Caveats:
- This method only applies to standards-compliant browsers (e.g., IE9 ).
- For older IE versions (e.g., IE8), a custom wrapper around the proper native functions using attachEvent may be necessary.

What is event bubbling and capturing in the DOM?
Jul 02, 2025 am 01:19 AM
Event capture and bubble are two stages of event propagation in DOM. Capture is from the top layer to the target element, and bubble is from the target element to the top layer. 1. Event capture is implemented by setting the useCapture parameter of addEventListener to true; 2. Event bubble is the default behavior, useCapture is set to false or omitted; 3. Event propagation can be used to prevent event propagation; 4. Event bubbling supports event delegation to improve dynamic content processing efficiency; 5. Capture can be used to intercept events in advance, such as logging or error processing. Understanding these two phases helps to accurately control the timing and how JavaScript responds to user operations.
