You cannot do it in JS file

After sending Ajax GET request, url will become ./js/abc.js?action=action&lt=lt . Hence, you are sending parameters to JS file & JS file will not execute or change automatically because .js extension. except: when you changed server configuration

Another way is: to change your file extension to .php or .html or whatever(JavaScript output in PHP file)

Like:

function add(lt,ln)
{
    $.ajax({
          type: 'get',
          url: "js/abc.php",
          data: {action: "addme", lt: lt,ln:ln},
          async: false,
          success: function(data){
           ///Do something with 'data'
           ///'data': var lt=lt; alert(lt);
            }
            });
}

js/abc.php :

<?php
   $action = $_GET["action"];
   if($action=="addme"){ //check if action=addme
      echo "var lt=".$_GET["lt"].";"; //Adding variable coming from Ajax request
    }?>
 alert(lt);

Try to understand code. Hope it will help you
