Subject: [Javascript] controlling layer visibility from another page
hi there,
i am trying to control layer visibility when clicking a link from another
page.

i have a series of text based menu items which i would like to access from
external links. i created the layers in dreamweaver and need a script that
will force hidden layers to show when accessed from another page.

Can't you put the layers you want to show in a querystring?

<a href="mypage.asp?show=1,2,3">Go</a>

Then grab the id's and script accordingly. Alternatively, can you use the
document.referrer property to get the referring page and script the layers
based on that?
