How to loop through a ASP.NET Repeater Control using JQuery?

How to loop through a ASP.NET Repeater Control using JQuery?

Hi.
I have created a Announcement page which works as when the title is clicked, it discloses the contents and there is a close button to hide the contents then it only shows the title.

but the hide function of my close button only work for the first title and does not work for the other titles below it.

The list is a repeater control so I guess I have to loop thorugh this repeater list and create a different pointer so that it can hide each contents no matter how many they are opened.

Any help on my situation?
