Is it possible that document.getElementById("").value doesn't function properly when making an Ajax call?

Searching multiple times is a feature I want to incorporate into my project. However, after adding AJAX for filter search, the code utilizing document.getElementById("").value no longer works as expected.

        $(document).ready(function() {
            $('#job_no').change(function() {
                $.ajax({
                    type: 'POST',
                    data: {JOB_NO: $(this).val()},
                    url: 'select.php',
                    success: function(data) {
                        $('#input_na').html(data);
                    }
                });
                return false;
            });
        });

<script type="text/javascript>document.getElementById('input_na').value = "<?php echo $_POST['input_na'];?>";</script>

Answer №1

Give this a shot:

$(document).ready(function() {
  $('#job_no').change(function() {
    var $currentJob = $(this); 
    $.ajax({
      type: 'POST',
      data: {JOB_NO: $currentJob.val()}, 
      url: 'select.php',
      success: function(data) {
        $('#input_na').html(data);
      }
    });
    return false;
  });
});

Make sure to assign the value of 'this' in the $.ajax(...) function to another variable like "$currentJob" for clarity and ease of use inside the ajax function.
