404 error because of ajax code?

I have a form with action="" and many AJAX codes to validate or chain-select the form elements as below.

** My current code (Simplified) **

<?php
if( isset( $_POST['create_transaction'] ) ) {
 // do something
}
?>

<div>
  <!-- period information will be filled up by ajax -->
  <input type="text" name="period" class="form-control" id="period" readonly />
</div>

<form id="form" method="post" action="">
  <input name="r_date" type="date" value="<?php echo isset( $_POST['r_date'] ) ? $_POST['r_date'] : date( "Y-m-d" ); ?>" class="transaction_date" />
  <input type="submit" name="create_transaction" value="Create" />
</form>

<script>
jQuery(document).ready(function($) {

  // Do this and that...


  /*  Get period information if date is already filled up on page load */
  var ajaxurl = '<?php echo admin_url('admin-ajax.php'); ?>';
  var $transaction_date = $(".transaction_date").val();

  if( $transaction_date ) {
    // call ajax for period <-- THIS IS THE PROBLEM CHILD.
    jQuery.ajax({
        url: ajaxurl,
        data: 'action=get_period_by_date&transaction_date='+$transaction_date,
        type: 'GET',
        success:function(results) {
            jQuery("#period").val(results);
        }
    }); 
  }

});
</script>

Here I am retrieving a period name using the input date. For example, if the date is 2014-01-01, then the #period div will be filled up with PERIOD-01. If the date is 2014-08-25, then the #period div will be filled up with PERIOD-08. This date field is auto-filled up with today's date when the page loads.

The problem is that if I insert the AJAX code to retrieve period information using the date input, submitting the form (clicking the 'create' button) leads to 404 error. If I remove the code, the form works well.

There doesn't seem to be a problem in the get_period_by_date function since it correctly retrieves and shows period name.

What would be the cause of my problem?

404 error means that your AJAX request leads to an unexisting path. Thats the first issue you should solve :).

Use your console to debug this one:

 var ajaxurl = '<?php echo admin_url('admin-ajax.php'); ?>';

You are using this var in a jQuery method. I think it will be literally interpreted. I don't think it's possible to use php syntax here.

I'm not sure if it's a good practice, but for a quick fix you could make a hidden field in your html page with that tag. And then you could easily get the value from it with the use of jQuery or javascript
