Window frame width and height property

[cschang]

I am not sure this is the right place to ask this question. I have a
web page composed with two frames (left and right). Then in my
frmae2(right one) , I open a pop-up window by javscript:
window.open(... ). I hope the pop-up window has the same size of the
frame2, therefore I use the document.body.i nnerHeight and InnerWidth
(this is on IE 6), but My question is how can I get the left-top
position of the frame2 so that I can use the moveTo() to superimpose the
pop-up window over the frame2. It will make the popup looks like laid
top of frame2 at least from the openning of the main window. I can not
find anything about the frame.height and .width. Can anyone give me a
clue?

Questions about the scripting of web pages are the main subject of this
group.

Pop-up blocking means that maybe you don't open a new window for a
proportion of users.

Hope?

innerWidth/Height are not intended to report client area dimensions. On
IE clinetWidth/Height are more useful, though on IE 6 it may not be the
body that they should be read from (depending on the value of
document.compat Mode).

Given a mouse event object, you can use the difference between clinteX/Y
and screenX/Y to calculate the screen co-ordinates of the top left
corner of the client area. However, there is no cross-browser method of
positioning a new window at those co-ordinates (even with browsers that
are capable/willing to open new windows).

Scripted control of window positioning is being increasingly restricted
due to abuse of the facility, so this is an optimistic desire.

As you have extremely restricted control over window chrome this seems a
value-less activity.

It strikes me that wanting to alter the user's display in an area
restricted to that of a frame in a browser, the sensible approach would
be to restrict activity to within that frame.

With IE you can use
window.screenLe ft
window.screenTo p
from inside the frame to find position relative to the screen.
