reload help!!!

I am not sure whether this is related to PHP. I'm using PHP and Javascript to do my program. I have some problem with my reloading parent window. In my program, I have a delete button which will pop up a child window once the user clicked the button. In the child window will have two option of delete buttons. Once the user clicked either one button, i want the child window to be close and at the same time the parent window will reload. How should I do this. Please give some advise or tips to me. thanks.
