It works in IE because the 'filter' CSS property is a non-standard IE extension. MSDN: filter attribute, values.

Though there is no alpha/opacity property in CSS 2.1, CSS3 will have it.

Other browsers support opacity properties to varying degrees. Mozilla has a non-standard CSS extension called -moz-opacity. It takes a value between 0 and 1.0, though, as does Safari. Opera 9 will support opacity. I don't think Konqueror supports it at all.

This can be very fiddly to make work across platforms. It has nothing to do with your getElementById selector.

well...

Actually, it's more like:

var alph = 0;
function appear(){
alph += 10;
document.getElementById(object).style.filter = "Alpha(opacity="+alph+")";
setTimeout("appear()",10);
}

'
...
I think. 'cause it's on my other computer. My code works on IE, but I want to put it on the web for everyone, and I want people to see it.

document.getElementById() is possibly the most important function in the DOM, it's the basis for practically everything! Naming a replacement to this is functionally impossible, but am also certain you should be able to achieve the results you need with it.

Let us know if you're trying to do something like the following:

document.getElementById('elementname').style.background = 'black';

That'll set the elements background to black for instance. If you give us more details about what you're trying to do, and/or show us code we can help you more.

What exactly are you concerned about with it? I don't see any problems with getElementById and CSS properties. Whatever selector you use, you should ultimately operate on the same object, the same way.

Is something not working? Can you show us code?

Well, my main concern with it is with DHTML, changing CSS values, mainly "filter:Alpha(opacity=XXX)"

Hey kker, melcome to TWF!

I can't name a drop-in replacement to getElementbyId with the same parameters and return type -- that would be redundant.

Related methods are listed here: Section 1.2 Fundamental Interfaces in the DOM Core, mainly under Document Interface. getElementsByTagName is probably nearest to getElementById.

We could probably give you a more helpful answer if you give us details about your problem or what you're trying to achieve.
