auto refresh of a div

auto refresh of a div

I'm using the jQuery tabs at the moment to have tabs in my browser window. And in one of those tabs I have a div which contains the content of that tab.
Now I want to refresh that content say every one minute, when looking online the only solutions I found were where the contents of that div comes from a separate file. ( http://stackoverflow.com/questions/220767/auto-refreshing-div-with-jquery for example).
Is this really neccesary, or is there a way to refresh that div with the contents which are in there now.

I hope I made myself a bit clear in this post and that you guys understand my question, any help would gladly be appreciated!
