Reload Div Content with jQuery and Ajax
Problem:
You need to reload the content of a specific div on the click of a button without refreshing the entire page.
Code Sample:
<code class="html"><div role="button" class="marginTop50 marginBottom"> <input type="button" id="getCameraSerialNumbers" value="Capture Again" class="disabled" /> <input type="button" id="confirmNext" value="Confirm & Proceed" class="disabled marginLeft50" /> </div> <div id="list"> <!-- Content to be reloaded --> </div></code>
Incorrect Approach:
<code class="javascript">$("#getCameraSerialNumbers").click(function () {
$("#step1Content").load();
});</code>
This code is incorrect because the load() method needs a URL to load content from.
Solutions:
jQuery's load() method can be used with a URL to load remote content. However, to reload content from the current page, we can use the following approach:
- Use Absolute URL with Hash:
<code class="javascript">$("#list").load(location.href + " #list");</code>
This loads the content of the element with the ID "list" from the current URL. Note the space before the second "#" sign.
- Use Ajax:
Another approach is to use Ajax. With this approach, we make an Ajax request to the server, retrieve the content, and update the div.
<code class="javascript">$("#getCameraSerialNumbers").click(function () {
$.ajax({
url: "YOUR_ENDPOINT_URL",
success: function (data) {
$("#list").html(data);
},
});
});</code>
In this case, the "YOUR_ENDPOINT_URL" is the server endpoint that returns the content to be loaded into the div.
Additional Notes:
- Make sure that the "Capture Again" button is enabled before reloading the content.
- If you are using the Ajax approach, ensure that the server endpoint returns the content in the appropriate format (HTML or JSON).

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.
