How to Automatically Launch a Bootstrap Modal on Page Load
Bootstrap offers versatile modal windows to enhance user interactions. As a beginner in JavaScript, you may encounter challenges activating modals on page load. Let's delve into a practical approach to addressing this need.
According to Bootstrap documentation, modals can be invoked via JavaScript using the '$('#myModal').modal(options)' syntax. However, the documentation doesn't explicitly detail how to activate the modal on page load.
To resolve this, embed the modal within a jQuery load event placed in the head section of the document. This ensures that the modal pops up as soon as the page finishes loading. Here's an example:
JS
<script type="text/javascript">
$(window).on('load', function() {
$('#myModal').modal('show');
});
</script>
HTML
<div class="modal hide fade" id="myModal">
<div class="modal-header">
<a class="close" data-dismiss="modal">×</a>
<h3">Modal header</h3>
</div>
<div class="modal-body">
<p>One fine body…</p>
</div>
<div class="modal-footer">
<a href="#" class="btn">Close</a>
<a href="#" class="btn btn-primary">Save changes</a>
</div>
</div>
With this setup, the modal will automatically appear when the page loads. Additionally, you can still invoke the modal through a trigger element (e.g., a link):
<a class="btn" data-toggle="modal" href="#myModal">Launch Modal</a>
In summary, embedding the modal within a jQuery load event provides a straightforward way to display modals immediately on page load, even for JavaScript beginners.

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.
