JQuery and nested elements

Question

Using jQuery ...

I want to be able to take the parent div and search through any internal elements to find a specific element that can be nested in ANYWHERE with the parent element.

Then I take these elements and look at them and based on their value, disconnecting / activating different elements ...

I also want to make it so that I have several sets of parent divs that allow the functionality to work the same with the specific elements inside it ...

so if i have ...

<div class="parent">
    <table>
        <tr>
            <td>
                <input type="text" />
            </td>
        </tr>
        <tr>
            <td>
                <input type="text" />
            </td>
        </tr>
        <tr>
            <td>
                <input type="text" />
            </td>
        </tr>
        <tr>
            <td>
                <input type="submit" />
            </td>
        </tr>
    </table>
</div>

<div class="parent">
    <table>
        <tr>
            <td>
                <input type="text" />
            </td>
        </tr>
        <tr>
            <td>
                <input type="text" />
            </td>
        </tr>
        <tr>
            <td>
                <input type="text" />
            </td>
        </tr>
        <tr>
            <td>
                <input type="submit" />
            </td>
        </tr>
    </table>
</div>

Any changes that I make in the first set of text fields will enable / disable the submit button for the first group .. and the same for the second group.

jquery, , , div, div- SubmitDisable....

$(document).ready(function() {

    $('.SubmitDisable > input[type=submit]').attr('disabled', 'disabled');


    $('.SubmitDisable > input[type=text], input[type=textarea]').keyup(function() {
        $(this).siblings('input[type=submit]').removeAttr('disabled');

        $.each($(this).parent().children('input[type=text], input[type=textarea]'), function() {
            if ($(this).val() == "") {
                $(this).siblings('input[type=submit]').attr('disabled', 'disabled');
            }
        });

    });
});
