jquery get next input element value in

jquery get next input element value in

I have some piece of an html table which reads like
<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.
my jquery to get the element which has the class "myclass" is as follows.
$('.tInputd').keyup(function(){
var disc = $(this).val();
});
your help is greatly appreciated.
