使用多个按钮和PHP提交jQuery ajax表单

here is my problem:

<script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"></script>
<form id="roomform" action="room.php" method="POST">
<button name="room" value="Room01">IMG01</button>
<button name="room" value="Room02">IMG02</button>
<button name="room" value="Room03">IMG03</button>
<button name="room" value="Room04">IMG04</button>
<button name="room" value="Room05">IMG05</button>
<button name="room" value="Room06">IMG06</button>
<button name="room" value="Room07">IMG07</button>
<button name="room" value="Room08">IMG08</button>
<button name="room" value="Room09">IMG09</button>
<button name="room" value="Room10">IMG10</button>
<script type="text/javascript">
    var frm = $('#roomform');
    frm.submit(function (ev) {
            type: frm.attr('method'),
            url: frm.attr('action'),
            data: frm.serialize(),
            success: function (data) {


PHP using $_POST['room'] to get the room name Room01-Room10(Room100 maybe?) and doing something special. It works good. Now I need to do this using Ajax. Above code seems ok, but I cannot get any data(Room01-Room10) from it.

then I found this:

<form action="/vote/" method="post" class="vote_form">
    <input type="hidden" name="question_id" value="10" />
    <input type="image" src="vote_down.png" class="vote_down" name="submit" value="down" />
    <input type="image" src="vote_up.png" class="vote_up" name="submit" value="up" />

$(".vote_form").submit(function() { return false; });
$(".vote_up, .vote_down").click(function(event) {
    $form = $(this).parent("form");
    $.post($form.attr("action"), $form.serialize() + "&submit="+ $(this).attr("value"), function(data) {
        // do something with response (data)

but it seems not suitable to my case, my all buttons with same name="room" for $_POST['room'] and no class. and this not works:

$(function() {
    var _data= $('#roomform').serialize() + '&room=' + $(this).val();
      type: 'POST',
      url: "room.php?",
      success: function(html){
    return false;

anyone know how to solve this problem?

    Your (last) code is not sending AJAX requests because you attached the handler to the wrong input selector. Your buttons are button elements, not input elements. This should work:

    $('button[name=room]').click(function() { ...


    Your first code isn't working because your buttons are just buttons. You have to add the type attribute to let your form know you're pressing a submit button: <button type="submit"...>

    The serialize() method does not collect the data from a button element. Take a look to the documentation on this link: https://api.jquery.com/serialize/. In your code I would assume that your data object is empty.

    Also if you post several form controls (serialized) , they should have different name attributes.
