Can JavaScript Change a Browser\'s URL without Reloading the Page?

How to Alter Browser URL without Page Reload Using JavaScript

Problem Overview:
Users desire a JavaScript solution that modifies the browser's URL without triggering a page reload, allowing them to store page state in the URL. Additionally, they request the back button to revert to the original URL.

Solution:

While modern browsers support history.pushState() and history.popState() to manipulate the URL, legacy browsers require an alternative approach. For these browsers, utilizing the fragment identifier (#) is a viable solution.

Implementation:
Set the window.location.hash property to a string containing the desired state information. Then, either use the window.onhashchange event for modern browsers or implement periodic checks (e.g., using setInterval) for older browsers. Remember to also check the hash value on page load to initialize the page state.

Cautions:
Avoid conflicts with element IDs on the page, as the browser will automatically scroll to matching IDs. To enhance usability, consider utilizing plugins like jQuery's hashchange plugin, which offers support for multiple browser implementations.
