document.bgColor in Opera

[Just One]

Hi,

I'm trying to dynamically assign a div background the value of the document
background with a code like this:

var menuDiv = '<div style="visibility:hidden; ';
menuDiv = menuDiv + 'background-color:';
menuDiv = menuDiv + document.bgColor;
menuDiv = menuDiv + '></div>';

In IE and FF, that's working great but not in Opera. I don't really think
Opera is very popular but still, I'm wondering if what I want is easily
achievable with this browser?

Thanks

document.style.backgroundColor;

And then make sure it is defined as background-color in the CSS of the
body element.

Randy's suggestion will not work, try this:

var menuDiv = '<div style="visibility:hidden; ';
menuDiv = menuDiv + 'background-color:';
menuDiv = menuDiv +
(document.bgColor||
getComputedStyle(document.body,null).backgroundColor||'transparent');
menuDiv = menuDiv + '></div>';

Cheers, scripts.contact! That works great, even though I don't quite know,
let alone understand that method. I guess being stuck with JS1.3 and old
browsers is the reason, have to fast-forward to version 1.5 and Gecko-based
DOM (as I understand both FF and Opera try adhering to it).

Only because it should have been document.body.style.backgroundColor
