$ .get（）不工作Jquery

I'm tryin to get a value in URL from php file via $.get(), here is the code:

PHP folder called 'jquery_con4.php':

echo (isset($_GET['req'])) ? 'found':'notfound';

JQuery called 'pass.js':

$.get('connection/jquery_con4.php', function(data){
        alert(data);
});

the main folder called 'password_c.php' which include the javascript called 'pass.js' which has $.get but it shows me in note 'notfound', & if remove if echo, it shows be 'undefined index:req' --- URL is: 'http://localhost/series/skyface/password_c.php?req=65yDq0zI39UcRSF'

Thanks!

    http://localhost:8888/series/skyface/password_c.php?req=65yDq0zI39UcRSF

    In order to pass the 'req' value from the URL querystring to the jquery_con4.php script, you need a JS function that will grab it for you and pass it into an ajax request.

    Below is an example of how that might work.

    /series/skyface/password_c.php

    <!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Document</title>
</head>
<body>
  <script src="http://code.jquery.com/jquery-1.11.3.min.js"></script>
  <script src="../../main.js"></script>
</body>
</html>

    /main.js:

    jQuery(document).ready(function($) {

  function getParameterByName(name) {
    name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
    var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
        results = regex.exec(location.search);
    return results === null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
  }

  function success(data) {
    console.log(data);
  }


  $.ajax({
    url: '/connection/jquery_con4.php',
    data: {req : getParameterByName('req')},
    success: success
  });

});

    /connection/jquery_con4.php:

    <?php echo(isset($_GET['req'])) ? 'found' : 'notfound'; ?>
