javascript Jquery选择TD内的输入

Jquery select input that is within a TD

提问by carlg

Here is the HTML code that I copied/pasted using Firebug:

这是我使用 Firebug 复制/粘贴的 HTML 代码：

<div id="TBI">
<tr class="t-state-selected t-grid-edit-row">
    <td>8081</td>

    <td class="t-grid-edit-cell">
        <input id="ijn" class="text-box single-line valid" type="text" value=""  name="ijn"> 
    </td>

I'm able to access the 2nd cell of this table using the following:

我可以使用以下方法访问该表的第二个单元格：

$('#TBI tr.t-state-selected')[0].cells[1] 

and all works well.

一切正常。

But, how can I get a jquery reference to the input that is contained within the TD? Once I figure out how to get a selector for that text box, I can manipulate it as I wish.

但是，如何获得对包含在 TD 中的输入的 jquery 引用？一旦我弄清楚如何为该文本框获取选择器，我就可以随心所欲地操作它。

Thanks ahead of time for help!

提前感谢您的帮助！

Just try:

你试一试：

$("#TBI tr.t-state-selected input")

Or for the input inside the second td:

或者对于第二个 td 内的输入：

$("#TBI tr.t-state-selected:nth-child(1) input");

Demo: Fiddle
