jQuery获取输入字段的ID [英] jquery get id of input field

问题描述

我需要获取在共享点列表范围内的输入的ID. 看起来像下面的代码.

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>

现在我想获取输入的ID. 我尝试过:

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);

但是没有用. 有人可以帮我吗?

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

推荐答案

您可能想要这样:

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

但是由于您的HTML没有任何id为idEstablishmentRow的元素，因此很难确定您到底想要什么.

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