I want to make a post without refresh, where it opens a modal confirmation.
But it is re-updating the site when the post is submitted and when the e.preventDefault(); is placed the post does not send, because in the confirmation modal it does not load the data.
<form id="addEvent" method="post" action="">
<h2>Data</h2>
<input type="date" name="date" id="date" >
<div class='col-sm-4'>
</div>
<h2>Observações</h2>
<textarea placeholder="Observações" name="notes" cols="30" rows="10"></textarea>
<h2>Matéria</h2>
<select name="tags" id="mat" >
<?php
$add = new USER();
$stmt = $add->runQuery("SELECT * FROM materias ORDER BY id_mat");
$stmt->execute();
$m=$stmt->fetchAll(PDO::FETCH_ASSOC);
foreach($m as $mat) {
$materia = $mat['materia'];
?>
<option value="<?php echo $materia;?>"><?php echo $materia;?></option>
<?php }?>
</select>
<br>
<br>
<input type="submit" class="o-btn js-event__save md-trigger md-setperspective" data-modal="modal-18" id="dataform" name="dataform" value="AGENDAR">
</form>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script>
$("#dataform").click(function(){
$.ajax({
dataType:'html',
url:"ag-monitoria.php",
type:"POST",
data:$(this).serialize(),
beforeSend: function(data){
}, success:function(data){
alert("Dados Enviados");
}, complete: function(data){}
});
});
</script>
