Ajax requested content that appears without any event?

Ajax requested content that appears without any event?

Hi I have spend a lot of time trying to solve this problem.

I have web video player that can display adds by inserting a div tag on top of the player after an amount of seconds that I specify.

I would like to manipulate the content of the div tag with jquery but I can't do this since the div tag is not present when the document is loaded.

I have looked into several options.

But all the solutions seems to rely on an event to happen - a link is clicked, some element is mouseovered and then jquery runs throug the DOM again.

But in this case no event occurs! The user click play (on a flash player) remove the hand from the mouse and 15 secs later the div tag with the add is displayed.

Is there any way to select this div tag and manipulate the content?

And How?

Thanks.
