I'm trying to convert these forms to ajax (an example)

<table>
<tr>
            <td>Prov</td><td>Cod</td><td>Nombre</td><td>Precio</td><td>Stock1</td><td></td><td></td>
        </tr>

                <tr class="o d">
                    <td class="provName">Karabitian</td>

                    <td class="cod d">494011135</td>

                    <td class="alignright">$&nbsp;69.00</td>
                    <td class="center">-</td>
                    <td class="add">

                </nobr>
                </td>
                </tr>
</table>

But I cant figure out how to get the inputs from the same row i clicked

$('input[type=image]').click(function(){
    // insert voodoo go get inputs here
    // ajax call
    return false;
});

I can't do something like $(input[name="barcode"]) Any ideas?

Answer 1

you need to do sth like:

$('input[type=image]').click(function(){
    var image = $(this);
    var parent = image.parent(); // this will be the fieldset
    var neededInput = $('input[name=barcode]', parent);
    // do something with it
    return false;
});

Answer 2

inside your click function, this will be a reference to the image you clicked. So you can do

$(this).siblings()

or

$(this).closest('fieldset').find(...);
