How to add PHP in JAVASCRIPT?

I have tried using dots (.) and double quotation to add php code in javascript. But works nothing. Here is the code:

  $( ".box-hover" ).hover(
    function() {
    $( ".box-hover ").prepend( $(`<div class="gizfeatshare">
   <div class="postfb">
     <a nohref target="popup" onclick="window.open('http://ift.tt/OxyLGR','name','width=600,height=400')"><img src="http://ift.tt/1IdNFwg" width="45px" />
     </a>
  </div></div>`) );
    }, function() {
    $(this).find( "div" ).remove();
    }
    );

I want to add some PHP code in the link for Wordpress use. Here is the PHP code <?php get_permalink(); ?> and <?php echo "Content"; ?>
