How to Remove Hash Js from Your Website

If you're a web developer, you may have come across hash js in your code. A hash js is a method that adds a "#" to the URL of a page, which is often used by single-page applications (SPAs) to keep track of routing and state. However, if you're not using an SPA, it can be unnecessary and even cause issues with SEO.

Method 1: Removing Hash Js with JavaScript

If you're using hash js in your code and want to remove it, one way to do so is by using JavaScript. You can do this by placing the following code in a script tag on your HTML page:

// Remove Hash Js from URL
if (window.location.hash && window.location.hash === '#_=_') {
  window.location.hash = '';

This code checks if the URL has a hash and if it's equal to "#_=_", which is often added by Facebook authentication. If it matches, the code removes the hash from the URL.

Method 2: Removing Hash Js with Server-side Code

If you're using a server-side framework like PHP, you can remove hash js by adding the following code to your .htaccess file:

RewriteCond %{REQUEST_URI} ^/.*$
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ /#$1 [NE,R=301,L,QSA]

This code redirects any URLs with a hash to the same URL without the hash. It also preserves any query strings that may be present in the URL.

Method 3: Using HTML5 History API

If you're using an SPA and want to remove hash js, you can use the HTML5 History API. This allows you to change the URL of a page without causing a full page refresh.

You can use the following code to replace the current URL without the hash:

// Replace Hash Js with HTML5 History API
window.history.replaceState({}, document.title, window.location.pathname);

This code replaces the current state of the History object with an empty object and the current URL without the hash. This effectively removes the hash from the URL without causing a page refresh.


There are multiple ways to remove hash js from your website, depending on your use case and coding approach. Whether you choose to use JavaScript, server-side code, or the HTML5 History API, removing hash js can improve the SEO and user experience of your website.
