does getElementById() work in netscape

does getElementById() work in netscape, or is it just IE. And if its only IE, what substitute will work in both??

As document.getElementById() is part of the DOM, it will naturally work with any browser that is DOM compliant. So yes, that means it will work with NS 6 or above, but not NS 4 or below--to my understanding IE 5.5 and above also support the method, but I'm not 100% on the actual version number. If you want to achieve an equivalent effect in the older browsers, you will need to use their proprietary BOM's (Browser Objet Models) to access the elements you want.

Hope this helps.

Yes, it works in IE 5.5 for windows. Haven't tried on a Mac.

how do you substitute part or all of an object reference with a variable? Just wondering.

Well, if you're talking about the DOM, it would be something like the following:

var something = document.getElementById("ElementId");

The BOM's are similar, but withough the getElementById() method of course.

Hope this is what you were asking.

no thats not what Im asking. Ive seen in some site were the entire object reference was substituted with a variable
but I forgot how it was done
such as
x = "document.fdsa.asdf.value"
and than was somehow
used to reference an obect
To make this easier to understand:
lets say:

var x = prompt("type in something","")

somebody types the complete syntax for referencing something in the prompt (such as document.fdsa.asdf.value). than what ever the thing that x refers to would be alerted

alert( ((the value of document.fdsa.asdf.value)) )
and lets say document.fdsa.asdf.value = "hello"
so it would alert "hello" and not "document.fdsa.asdf.value"

is this what you mean?

var x = prompt("type in something","")
alert(eval(x));

of course, if the input is not a valid javascript expression, it will throw an error.
