accessing an object as variable

[shumway]

Im trying to move an image within an iframe. The problem is that I have the id of the iframe in a variable and I cant get it to work.



This works great:
Games.document.all['DivBorderTR'].style.left = 100;

But this doesnt:
$module = 'Games';
getElementById( $module ).document.all['DivBorderTR'].style.left = 100;

(I have several iframes that looks similar and this code is supposed to work for any iframe-id given in $module.)

You can look at it at: www.battlesite.com/henrik/battlesite2 (just press login-button - no userid or password required)

A JavaScript identifier, or name, must start with a letter or underscore ("_"); subsequent characters can also be digits (0-9). Because JavaScript is case sensitive, letters include the characters "A" through "Z" (uppercase) and the characters "a" through "z" (lowercase).

Thanks for your answer gil davis but im not sure I follow you. The id "Games" do follow the rules and variables starts with $-signs dont they - at least everything else works fine with that.

Actually you can use $sign to begin a variable name.

I think in your code you are not using document before getEle,,,,
getElementById( $module )
should be
document.getElementById( $module )
and instead of using document.all[] use document.getElementById
