[jQuery] Finding index of the first empty text field

[bikuta]

Hi all,

I'm trying to find the index of the first empty text field (class name
is item).

I am able to get the text field object by using:
$("[EMAIL PROTECTED]''"])

However I can't get the index, i.e., which text field is it?

The number of text fields are dynamic, but there will always be at
least one that is empty.

Using:
$("[EMAIL PROTECTED]''"]).index(this);
Returns:
-1

Also tried $(".item").index($("[EMAIL PROTECTED]''"]));
also returns -1

Anyone know how to do it?

Cheers.
