From jQuery Ajax add the below line

$('#discount option:selected').val();

You can print those values from the selected drop-down list by adding these below lines above the Ajax i.e, from JavaScript

var discount = $('#discount option:selected').val();
console.log(discount);

There is only a couple of things wrong with your code. See the working example below.

$(document).ready(function() {
  $('#discount').on('change', function() {
    alert($('#discount').val());
  });
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<select id="discount" onchange="discountPostback()" title="">
  <option value=""></option>
  <option value="0">نمایش کل</option>
  <option value="1">نمایش افراد با تخفیف</option>
  <option value="2">نمایش افراد بدون تخفیف</option>
</select>

You need to select the select using the ID which requires the # in your selector, and val() is the jQuery method to get the select's value and nothing else as shown below.

Fix

$('#discount').val()

jQuery .val()

jQuery ID selector
