AnchorPosition.js
Author: Matt Kruse
Last modified: 10/11/02
DESCRIPTION: These functions find the position of an <A> tag in a document,
so other elements can be positioned relative to it.
COMPATABILITY: Netscape 4.x,6.x,Mozilla, IE 5.x,6.x on Windows. Some small
positioning errors - usually with Window positioning - occur on the
Macintosh platform.
FUNCTIONS:
getAnchorPosition(anchorname)
Returns an Object() having .x and .y properties of the pixel coordinates
of the upper-left corner of the anchor. Position is relative to the PAGE.
getAnchorWindowPosition(anchorname)
Returns an Object() having .x and .y properties of the pixel coordinates
of the upper-left corner of the anchor, relative to the WHOLE SCREEN.
NOTES:
1) For popping up separate browser windows, use getAnchorWindowPosition.
Otherwise, use getAnchorPosition
2) Your anchor tag MUST contain both NAME and ID attributes which are the
same. For example:
<A NAME="test" ID="test"> </A>
3) There must be at least a space between <A> </A> for IE5.5 to see the
anchor tag correctly. Do not do <A></A> with no space.
