Modal form Submission to PHP using Jquery .ajax

问题:

I am trying to post a modal form to a table using php, jquery .ajax but it never works.. tried debugging using firebug and i don't see any errors. i tested the form by using form action="notes_functions.php" and it worked fine.

Profile.php

    <div class="modal-body">

        <form class="noteform" id="notesmodal" method="post">
           <fieldset>      
          <label>Title</label>
                <input type="text" class="form-control" name="note_title" placeholder="Enter a title for your note">
                <label>Note</label>
                <textarea rows="4" cols="50" class="form-control" name="note_content" placeholder="note"></textarea>
                <label>Note type</label>
                <div class="panel-body">
                    <input type="tagsinput" id="teetete" class="tagsinput" value="" />
                </div>                                                  
                <label for="exampleInputFile">Attach a document</label>
                <input type="file" id="exampleInputFile3">
                <p class="help-block">PDF, DOCX and image files are supported.</p>
            <div class="checkbox">
                <label>
                    <input type="checkbox"> Check me out
                    <input type="label" name="note_account" value="<?php echo $acctname ?>"/> 
                </label>
            </div>
            <input type="hidden" name="note_creator" value="<?php echo $_SESSION['username'];?>"/>
              </fieldset>
             <button class="btn btn-default" id="submitnote" >ADD</button>
        </form>
    </div>

this is my js code

$(function(){
  $("button#submitnote").click(function(){
    $.ajax ({
      type:"POST",
      url:"notes_functions.php",
      data: $('form.noteform').serialize(),
      success: function(msg){
        $("#thanks").html(msg)
        $("form.noteform").modal('hide');
      },
      error: function(){
        alert("failure");
      }
    });
  });
});

notes_functions.php

<?php

include_once 'dbconnect.php';

if (isset($_POST['note_title'])) {



        $notetitle = strip_tags($_POST['note_title']);
        $noteContent = strip_tags($_POST['note_content']);
        $noteAccount = strip_tags($_POST['note_account']);
        $noteCreator = strip_tags($_POST['note_creator']);

        mysql_query("INSERT INTO account_notes (note_title, note_contents, note_account, note_creator) 
            VALUES ('$notetitle','$noteContent', '$noteAccount', '$noteCreator') ");

        echo "Name = ".$notetitle;
        echo $noteCreator;




 }

?>

You should really be using .submit() rather than click (for submit-by-enter, etc.) and returning false to block conventional submits. You also need to make sure the code to bind the events runs after the form element is created. The easiest way to do this is to put it in the document ready handler.

jQuery(document).ready(function ($) {
    $("#notesmodal").submit(function () {
        $.ajax({
            type: "POST",
            url: "notes_functions.php",
            data: $('form.noteform').serialize(),
            success: function (msg) {
                $("#thanks").html(msg)
                $("form.noteform").modal('hide');
            },
            error: function () {
                alert("failure");
            }
        });
        return false;
    });
});

And change the ADD button to be:

<input type="submit" name="submit" class="btn btn-default" id="submitnote" value="ADD" />
