JQuery .each loop prob

Question

Okay so here's the idea:

I want to make a jQuery script to handle multiple forms. Every form has a button. When you click this button the script should send all input fields' name and value in $_POST to the form's action URL. But I can't make it work.

It won't loop through my .each on line 3 in my jQuery file.

jQuery:

$("input[type='button']").click(function(){
    var query = {};
    $(this).parent('form').children('input[type="text"]').each(function(){
        query[$(this).attr('name')] = $(this).val();
    });

    $.post($(this).parent('form').attr('action'), query, function(data) {
        $("#dialog").html(data);
        $("#ui-id-1").html('Activate account');
        $("#dialog").dialog("open");
    }, 'json');
});

HTML:

<form action="/action/activateacc.php">
<table>
    <tr>
        <td>E-mail:</td>
        <td><input type="text" id="mail" name="mail" /></td>
        <td><img class="tick" id="mailIMG" width="20px" /></td>
    </tr>
    <tr>
        <td>Activation code:</td>
        <td><input type="text" id="code" name="code" /></td>
        <td><img class="tick" id="codeIMG" width="20px" /></td>
    </tr>
    <tr>
        <td>Choose organization-name:</td>
        <td><input type="text" id="name" name="name" /></td>
        <td><img class="tick" id="nameIMG" width="20px" /></td>
    </tr>
    <tr>
        <td></td>
        <td style="text-align:center"><input type="button" style="cursor:pointer" value="Activate account" /></td>
    </tr>
 </table>
 </form>

Answer 1

Just use .serialize() with the form to get name/values of your inputs- also you should be using closest since parent only goes up one level

$("input[type='button']").click(function(){   
    var query = $(this).closest('form').serialize();
    $.post($(this).parent('form').attr('action'), query , function(data) {
        $("#dialog").html(data);
        $("#ui-id-1").html('Activate account');
        $("#dialog").dialog("open");
    }, 'json');
});
