Uncaught ReferenceError: id is not defined at HTMLButtonElement.onclick
<p>I'm trying to code a detailed ticket information from database that could be deleted by the admin. I want to use jquery ajax to remove it once the user have click on the button</p>

<p>my codes are :</p>

<p>`</p>

<pre><code>&lt;form class="white" method="post" action="" id="frmBA2N29F"&gt;
&lt;span class="col3"&gt;BA2N29F&lt;/span&gt;
&lt;span class="col3"&gt;Medan(KNO)&lt;/span&gt;
&lt;span class="col3"&gt;Jakarta (CGK)&lt;/span&gt;
&lt;span class="col3"&gt;BA&lt;/span&gt;
&lt;span class="col2"&gt;BA001&lt;/span&gt;
&lt;span class="col4"&gt;2016-01-01&lt;/span&gt;
&lt;span class="col3"&gt;05:00:00&lt;/span&gt;
&lt;span class="col3"&gt;07:00:00&lt;/span&gt;
&lt;span class="col1"&gt;60&lt;/span&gt;
&lt;span class="col3"&gt;560000.00&lt;/span&gt;
&lt;span class="col3"&gt;560000.00&lt;/span&gt;
&lt;span class="col3"&gt;280000.00&lt;/span&gt;
&lt;button class = "delete" type="button" id="deleteBA2N29F" onClick = "delete_row(BA2N29F);"&gt;delete&lt;/button&gt;
&lt;/form&gt;
</code></pre>

<p>`</p>

<p>my javascript function :</p>

<pre><code>&lt;script type="text/javascript" src="../../JS/jquery-3.1.1.min.js"&gt;&lt;/script&gt;
    &lt;script&gt;
function delete_row(id)
{
 $.ajax
 ({
  type:'post',
  url:'delete-ticket.php',
  data:{
   delete_row:'delete_row',
   row_id:id,
  },
  success:function(response) {
   if(response=="success")
   {
    var row=document.getElementById("frm"+id);
    row.parentNode.removeChild(row);
   }
  }
 });
}
&lt;/script&gt;
</code></pre>

<p>and my delete-ticket.php code :</p>

<pre><code>&lt;?php
include_once '../../database.php';
if(isset($_POST['delete_row']))
{
 $row_no=$_POST['row_id'];
 mysqli_query($connection,"delete from flight where flight_id='$row_no'");
 echo "success";
 exit();
}
?&gt;
</code></pre>

<p>The message that I got from my browser is </p>

<pre><code>tiket-list.php:98 Uncaught ReferenceError: BA2N29F is not defined
    at HTMLButtonElement.onclick
</code></pre>

<p>So what's the error in my code?</p>
