Thanks, Rick! That's an excellent example, and I could achieve my
functionality with that. However, I would like to know if we could
access the value with the text box name also. For example, if we know
that the text box's name is text_1, then we could use like:
$("form input#text_1").attr("value");
In this case the name is dynamically generated. So, I tried with
txt_name = "text_" + i;// i is a counter
$("form input#" + txt_name).attr("value");
But this doesn't seem to work. Any syntactical error?
This way of working would be useful in other cases too. For example,
if we want to know the value of the i-th text box.
Thanks,
Barun.

Thats brilliant. i'd be interested in working on that if the need arises (test
cases etc)

Well I had a thought. It might be a bad thing to add extra code into
JQuery simply to check if the developer has been stupid. It'd be
better to have a plug in that developers can add and temporarily use.
I'm working on such an proof of concept plug in, so I'll post here
again with the example.
