[jQuery] refresh a link

[jQuery] refresh a link

Hi Poeple,
I am looking for ideas on ho wto do the following.
I have a link in a web page that points to a live audio stream but
this link only shows up is the stream in on otherwise you do not see the link to the stream.
The way is working now is that I have to refresh the entire page in order to see the link
to the stream.  I do not want to refresh the entire page because it is using a div that display
of hides a list of previous meetings.
If I set up an autorefresh then the user could be looking at the list of previous meetings and when it is refresh
the list will be automatically hidden.
How do I accomplish the refreshing of the link only and not the entire page.
I hope that is not too confusing.
Thanks,
Rotsen
