Send Email to a specific record in the list using Javascript

Question

I have a comment list and I would like to send a specific email to a person on the list, but sending does not happen.

When I click on Answer back, the form box to fill the answer normally opens, however, by clicking on Send Email is not sent.

Follows the code:

while($painel_comentarios_artigos=mysqli_fetch_array($artigos_comentarios))
{

$idcomentario = $painel_comentarios_artigos['id'];
echo "<div class='titulo_comentarios'>".$painel_comentarios_artigos['nome']."</div><br>";
echo "<div class='msg_comentarios'>".$painel_comentarios_artigos['msg']."</div><br>";
echo "<div class='responder_comentarios'>
<a class='displayDiv' div-id='{$idcomentario}'>Responder</a>
</div><br>";
echo "<div id='div{$idcomentario}' style='display: none' class='txt_comentarios'>

<form div-id='{$idcomentario}' method='post'>
<textarea class='textarea_responder' name='cmt_resp'></textarea>
<input type='hidden' name='codigo' value=''>
<button class='btn_responder' type='submit'>Enviar</button>
<div id='msg_sugestao_resposta'></div>
</form>

</div><br>";

}
?>
</div>

<script>
$( "a.displayDiv" ).click(function() {
var id = $(this).attr('div-id');

$('div.txt_comentarios').css('display','none');
$('#div'+id).fadeIn(500);

// ENVIO DA RESPOSTA

$(function(){

  $('#id').submit(function(event) {
    event.preventDefault();
    var formDados = new FormData($(this)[0]);

    $.ajax({
      url:'resenviar.php',
      type:'POST',
      data:formDados,
      cache:false,
      contentType:false,
      processData:false,
      success:function (data)
     {document.getElementById('msg_sugestao_resposta').innerHTML = 'Sugestão enviada com sucesso.';
        $('#id').each (function(){
      this.reset();
           });
    },
      dataType:'html'
    });
    return false;
  });
});

// FIM DO ENVIO DA RESPOSTA

});
</script>
