[javascript] refresh div with jquery

I'd like to refresh a div. It should have new information from the server on it. All the other answers assume that you've gotten the new data from your $.ajax request and tell you to load that data onto your div, hide it, and show it again, like so:

$("#panel").hide().html(data).fadeIn('fast');

I know, I know, I probably should just get data with Ajax. But right now, I want to just refresh the div, without refreshing the page, and without putting new HTML into the div. Is this possible?

I tried the first solution and it works but the end user can easily identify that the div's are refreshing as it is fadeIn(), without fade in i tried .toggle().toggle() and it works perfect. you can try like this

$("#panel").toggle().toggle();

it works perfectly for me as i'm developing a messenger and need to minimize and maximize the chat box's and this does it best rather than the above code.
