Answer 1

As Mike X and Naltroc said you can do it using jQuery, here is an example code:

$(".fb-send").click(function(event){
    event.preventDefault();// this will stop redirecting to other page
    $(this).attr("href", "https://www.google.com");
});

Answer 2

 <p><a href="https://www.w3schools.com" id="w3s">W3Schools.com</a></p>
 <button>Change href Value</button>

 <script>
 $(document).ready(function(){
     $("button").click(function(){
        $("#w3s").attr("href", window.location.href);
     });
 });
 </script>

finaly i got my answer window.location.href with some jquery did that job perfectly.
