[Javascript] indexing page sections

[David Levy]

I'd like to, without reloading, have certain sections of text appear or
disappear using a switch.  In order to do this I thought that if I could
name parts of the page in a way that javascript could detect it, I could
show or hide that part of the page.  Does anyone know if there's a way to
assign a variable or object name to a portion or a web page?

David.
