Loading Images Dynamically from a Folder Using jQuery/JavaScript
Navigating folders to load assets like images can be challenging when their names are non-sequential. However, jQuery provides a solution to retrieve and display images from any directory.
Solution:
Implementing this solution involves utilizing an AJAX call to fetch the content of the target folder:
<code class="javascript">var folder = "images/";
$.ajax({
url : folder,
success: function (data) {
$(data).find("a").attr("href", function (i, val) {
if( val.match(/\.(jpe?g|png|gif)$/) ) {
$("body").append( "<img src='"+ folder + val +"'>" );
}
});
}
});</code>
This approach uses jQuery to parse the HTML response from the AJAX call. It then iterates over the anchor tags within the response, filtering out only those ending with supported image file extensions. Finally, it dynamically appends these validated image paths to the DOM.
Note:
For this solution to work effectively, it's crucial to configure your server to allow folder listings. In Apache servers, the option "Indexes" should be enabled. For Express.js and Node.js, an external package named "serve-index" can be utilized to achieve the same functionality.

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.
