Preventing Browser Back Button Activity in JavaScript
Disabling the browser back button is a common topic in JavaScript development. However, it's important to understand that browser security protocols can make it difficult to prevent users from navigating back in their history.
One approach that has been attempted is calling window.history.forward(); and defining a noBack() function that repeatedly calls window.history.forward();. However, this method can interfere with other scripts, particularly those involving timers.
The best practice is to provide a friendly warning to users that their work may be lost if they navigate away from the page:
window.onbeforeunload = function() { return "Your work will be lost."; };
While this approach doesn't completely disable the back button, it serves as a reminder to users that they are in a secure environment and should only leave the page if their work is complete.
It's also worth noting that the page at http://www.irt.org/script/311.htm lists various techniques for disabling the back button, but it cautions that these methods are not guaranteed to work due to browser security policies.

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.
