javascript to refer runtime-created gridview

Question

Dear all,
I have a question which is a little complicated. I want to refer  a runtime-created GridView Control through Javascript, But the GridView is placed in a PlaceHolder <asp>, the PlaceHolder <asp> is placed in a Panel <asp>. How can I use Javascript to refer to it? Thanks
