How to Remove a URL Hash Without Refreshing the Page Using JavaScript?

Removing the Hash from URL without Page Refresh Using JavaScript

When you encounter URLs like "http://example.com#something" with a hash component (#) at the end, removing it without refreshing the page can prove challenging. Traditional methods involving setting the "window.location.hash" to an empty string fail to remove the hash symbol itself.

Solution: HTML5 History API

Modern browsers provide a solution through the HTML5 History API. By utilizing the "history.pushState()" function, we can modify the location bar to display a new URL without triggering a page refresh.

function removeHash() {
    history.pushState("", document.title, window.location.pathname
                                                       + window.location.search);
}

This method effectively removes the hash from the URL in current and compatible browsers, including Chrome, Firefox, Safari, Opera, and Internet Explorer 10 and above.

Graceful Degradation for Unsupported Browsers

For browsers that do not support the History API, you can employ a graceful degradation script:

function removeHash() {
    var scrollV, scrollH, loc = window.location;
    if ("pushState" in history)
        history.pushState("", document.title, loc.pathname + loc.search);
    else {
        // Preserve current scroll position
        scrollV = document.body.scrollTop;
        scrollH = document.body.scrollLeft;

        loc.hash = "";

        // Restore scroll position
        document.body.scrollTop = scrollV;
        document.body.scrollLeft = scrollH;
    }
}

This approach ensures compatibility across different browsers, eliminating the hash symbol without causing page refreshes.

Note:

• To replace the current history entry instead of adding a new one, use "replaceState()" instead of "pushState()".
• Removing the hash is dependent on browser support. However, this solution provides a comprehensive approach that covers both supported and unsupported browsers.
