JQuery :: Determine The Position (index) Of A Particular Textbox In A Textbox Array?

I have two textbox columnsof equal length they are accessed in the following manner:

taborder 1
taborder 2 taborder 3 taborder 4 taborder 5 taborder 6 taborder 7 taborder 8

When I leave the first textbox (taborder 1), I need to check and see if the textbox contains avalue. If it does, then I need to check and see if the second textbox (taborder 2)contains a value. If it doesNOT, then I need to loadthe second textboxwith "100" and highlight (select) the text. I am adding a blur event to all the column one textboxes as they all contain"rawCount" in the id. Here is my blur event code:

$(document).ready(function(){
$('input[id*=rawCount]').bind('blur', function (event) {
// Code to go here
});
});

What I am trying to do isadd thecode tocheck and update thecolumn two textbox in the corresponding row (same index)to the blur event of the column one textboxes without having to loop the array each time to find the current textbox array position. Since it is adding the blur event, it has to be possible.
