How to Update a Portion of a Page Without Reloading using jQuery/AJAX
Reloading a specific div on a button click without affecting the entire page is a common requirement in web development. This can be achieved using jQuery's AJAX functionality.
Example
Suppose you have a button that, when clicked, should update the content of a div called div1. Here's how you can do it:
HTML:
<code class="html"><input type="button" id="myButton" value="Update DIV" />
<div id="div1">
<!-- Content to be updated -->
</div></code>
jQuery:
<code class="javascript">$("#myButton").click(function() {
$("#div1").load(location.href + " #div1");
});</code>
Explanation:
- The jQuery click event handler is attached to the button with the id myButton.
- When the button is clicked, the load() function is called on the div with the id div1.
- The load() function loads the content of the specified URL into the div.
- In this case, the URL is location.href " #div1". This retrieves the current page's URL and appends the #div1 selector.
- The space before the second # sign is crucial. Without it, the above code will reload the entire page within the div.
- As a result, when the button is clicked, the content of div1 will be updated with the content of the same div from the current page.
Note: Remember to include the jQuery library before using the above code.

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.
