How to open links of ajax page in same ajax part?

hey guys,
i was using $.ajax method to get my ajax page on my main page,
which is working great.

But now if i have links in that ajax page then i can't open them in that same div,
the links are opening in new window,
but i want to open in same part,

i tried google it and then found, i have to use iframe instead of div.

So,
can any one gave me any idea how to do with only use jquery and div.

Thanks in advance....
