I have only an index.html file and I don't want to add php file to my html file so please help me with a simple and clean code.

Answer 1

If you want a dynamic solution, that will update the page title everytime the anchor/hash changes:

$(function(){
  // event
  $(window).on('hashchange', function() {
    let hash = location.hash.replace( /^#/, '' );
    document.title = 'example ' + hash;
  });

  // just to set on page load (you might need to tweak in case there is no hash)
  $(window).trigger('hashchange');
});

Answer 2

You have to use atleast javascript.

Try this:

 var str = 'example.com/#city1'; var str1 = str.substring(0,str.indexOf('.'))+' '+str.substring((0,str.indexOf('#')+1)); document.getElementsByTagName('p')[0].innerHTML = str1; //in your case replace p with title tag
