Targeting Specific Bootstrap Tabs with External Links
Query:
How can I navigate to a specific Bootstrap tab when clicking on an external link, ensuring the desired tab remains active upon page reload?
Answer:
To achieve this functionality, implement the following JavaScript code:
// Javascript to enable link to tab
var hash = location.hash.replace(/^#/, ''); // ^ means starting, meaning only match the first hash
if (hash) {
$('.nav-tabs a[href="#' + hash + '"]').tab('show');
}
// Change hash for page-reload
$('.nav-tabs a').on('shown.bs.tab', function (e) {
window.location.hash = e.target.hash;
})
Explanation:
- Locating the hash: Retrieve the hash (part following the "#") from the current URL.
- Activating the tab: Search for a tab link that matches the hash and toggle it to show.
- Preserving the hash on reload: Update the URL hash when a tab is shown to maintain its active status upon page reload.

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.
