Ajax提交不起作用

Question

$(document).ready(function(){
  $("#form1").submit(function (e){
        alert ('working 01');
            e.preventDefault();
            var $form = $(this);
        alert ('working 02');
         $.ajax({
                type: 'POST',
                url : '../portal.php',
                data: $('#form1').serialize(),
                success: function(response) {
                $('#form1').fadeOut("slow");
                alert ('working 03');
                }

                })
  });
  return false;
});

I have echoed in several places to see where it goes wrong. only "working 02 is displayed and nothing happened. portal.php is ready to accept data. Here's my form.

 <form id="form1" method="post">
          <label class="label_title"> e-mail </label>
          <input type="text" id="email" required>

          <label class="label_title">Comments:</label>
          <textarea cols="50" rows="10" name="com" id="com" class="textarea required" required ></textarea>
          <input type="submit" class="button" value="Send">
          </form>

you can't use submit and ajax, it's better to use click:

$(document).ready(function(){
  $(".button").click(function (e){
        alert ('working 01');
            e.preventDefault();
            var $form = $(this);
        alert ('working 02');
         $.ajax({
                type: 'POST',
                url : '../portal.php',
                data: $('#form1').serialize(),
                success: function(response) {
                $('#form1').fadeOut("slow");
                alert ('working 03');
                }

                })
  });
});

P.S. it's better to remove the type="submit" from your button

UPDATE:

$(document).ready(function(){
  $(".button").click(function (e){
        alert ('working 01');
            e.preventDefault();
            var $form = $(this);
        alert ('working 02');
         $.post('../portal.php',{data:$('#form1').serialize()},function(response){
             $('#form1').fadeOut("slow");
             alert ('working 03');
         });
  });
});
