Converting a static site to ajax?

Question

PHP

I have a static site in PHP. Works through rewrite, i.e. when you click on the link: site.ru/about/ index.php is constantly called and displays the desired page, i.e. separate PHP file.
Here is .htaccess

AddDefaultCharset utf8
DirectoryIndex index.php
RewriteEngine On
RewriteBase /
RewriteCond %{SCRIPT_FILENAME} !-f
RewriteCond %{SCRIPT_FILENAME} !-d
RewriteRule ^(.*)$ /index.php [QSA,L]

Tell me how to implement the call pages via ajax, like this: "site.ru/!#about" without reloading. I am not strong in this, so I ask you for help.

Answer 1

and why do you need it? Just judging by your question, you are just starting to learn about php, web servers, and js.
Better a simple but working site than a buggy site with such a load.
Oh yeah, if you haven't changed your mind:

You are right, I am new to this business, but the customer's decision is necessary!
