jquery get id of input field

Question

i need to get the id of a input that's inside a span of a sharepoint list. it looks like the code below.

<tr id="idEstablishmentRow">
<td class="ms-formbody" vAlign="top">
<span dir="none">
<span style="vertical-align: middle;">
<input type='text' id='hello' />
</span>
</span>
</td>
</tr>

now i want to get the id of the input. i have tried:

    var _test = $('#idEstablishmentRow').find('td.ms-formbody');
    var _test1 = _test.find('span.style');
    var _test2 = _test1.find('input');
    var _test3 = _test2.attr('id');
    alert(_test3);
    alert(_test2);

but it didn't work. could anyone help me ?

Solution 1

You might want this :

var id = $('#idEstablishmentRow td.ms-formbody span input').attr('id');

But as your HTML doesn't have any element whose id is idEstablishmentRow, it's hard to be sure of what you exactly want.

Demonstration

Solution 2

var inputId = $("span input").attr("id");

i have a sharepoint list with alot of trs/tds, the idestablishmentrow is the id of the row forgot to put it in sorry.

So that should work. Maybe you want to replace td with td.ms-formbody too, depending on your real HTML.
