来自选择框和复选框的数据

Question

I want to get data from my select/dropdown box and from my checkboxes. I get the data from the input fields like this:

 'formData'         : {
   'timestamp' : '<?php echo $timestamp;?>',
   'token'     : '<?php echo md5('unique_salt' . $timestamp);?>',
   'parentId'      : $('input[name=parentId]').val(),
   'projectnr'      : $('input[name=projectnr]').val(),
   'gebruiker'      : $('input[name=gebruiker]').val(),
   'gebruikerid'      : $('input[name=userId]').val(),
   'uploadbash'      : '<?php echo $uploadbash; ?>'
 },

How do I get the selected value from my <select> field and checkboxes?

I tried:

  'groepId'      : document.getElementsByName("map")

But it doesn't work...

The select looks like this:

<select name="map" id="map">
                                <option value="0">Algemeen</option>
                <?php
                    if(mysql_num_rows($query_select_map) != 0)  {

                        while($fetch_map = mysql_fetch_assoc($query_select_map))    {
                            if($fetch_map['parent'] != "")  {
                                $voegtoe = ">";
                            }
                            echo '<option value="'.$fetch_map['id'].'">'.$voegtoe.' '.$fetch_map['naam'].'</option>';
                        }
                    }
                    ?>
                            </select>

Weird thing, i build in this check:

<script type="text/javascript">
$(document).ready(function(){
$('#zenden').click(function(){
alert($('#map').val());
});
});
</script>

When I submit I get the right number of the selected item in my alert box, but it sends the wrong number the next page. All other data is right...

怎么样：

$("input[name=map]:checked").val();
