JQuery :: Get A Reference To The Textbox That Fired Blur Even, Then Get The Row Of The Matching Textbox

<script type="text/javascript">
$(function () {
$('input[id *=txtAmt]').blur(function () {
var txtBoxThatChanged = $('How do i get a reference to the textbox that changed?');

[Code]....

In my grid each row has a twin row (not consecutive) the rows each have 1 text box with a name containing txtAmt. When a user enters a value in the text box in a row. I need to put that value in the text box in the twin row. i got the blur function to work on each text box but do not know how to do the rest. I typed a description of the selector in each $().
