How to check the LAST TAB?

Hi!
I have several input text and every input text has its tabindex property!
When I open the page, if I push the tab, cursor sets itself on the first input text having the property tabindex=1.
It's correct.
The the cursor moves itself on the other field.
BUT when I reach the last tab the cursor moves itself up to the document and not on the first tab with tabindex=1.
It's correct because tab works in this way but then:
HOW can I obtain the cursor setted on the first tab???

Thanks a lot

Not understanding your last sentence..aka the real question?

You want to force it to go to the first element?

Sorry for late.
Yes, the first element, which has tabindex=1!

Thank you
