jquery get next input element value in <td>
提问by Ela Buwa
I have some piece of an html table which reads like
我有一些 html 表格，它读起来像
<table>
<tr>
<td>
<input type="text" class="myclass" name="first_ele[]" value="100" />
</td>
<td>
<input type="text" class="anotherclass" name="secon_ele[]" value="" />
</td>
</tr>
</table>
I have a piece of jquery that will get the value of the element that contains class "myclass" on keyup and I am getting the proper value. I need to get the value of the next input element. FYI , The table gets rows added dynamically. My issue is I don't know how to point to the next available input element.
我有一段 jquery，它将在 keyup 上获取包含类“myclass”的元素的值，并且我得到了正确的值。我需要获取下一个输入元素的值。仅供参考，该表会动态添加行。我的问题是我不知道如何指向下一个可用的输入元素。
my jquery to get the element which has the class "myclass" is as follows.
我的jquery获取具有类“myclass”的元素如下。
$('.tInputd').keyup(function(){
var disc = $(this).val();
});
your help is greatly appreciated.
非常感谢您的帮助。

var disc = $(this).closest('td').next().find('input').val();
});

或者
