Even simpler (shorter):

var d=document;
function o(id){
    return d.getElementById?d.getElementById(id):(d.all?d.all[id]:(d.layers?d.layers[id]:null));
}

I have tested this code, and it seems to return the id for the tag name and field name passed. This piece of code has helped resolving the issues with fetching element ids

function getElementId(_tagName,_fieldName) {
	var elements = document.getElementsByTagName(_tagName);
	if (elements != null && elements.length != 0) {
		for (i=0, x=elements.length; i<x; i++) {
			if(elements[i].id.match(_fieldName) != null) {
			return elements[i].id;
			}
		}
	}
}

For null checks as well the code which i have used and I feel it can be of help to this forum:

function IsNotEmpty(aTextField) {
	if (aTextField != null) {
		if (( aTextField.value == 'undefined') || (aTextField.value == null)) {
			return true;
		} else {
			return false;
		}
	} else {
		return true;
	}
}

var ThisIsYourElementID = document.GetElementByID('ThisIstheIDofYourElement');

You might find this site interesting too:

http://webbugtrack.blogspot.com/2007/08/bug-152-getelementbyid-returns.html

It points out that the getElementById method in IE6 and IE7 is *STILL* broken! and will return the wrong objects (if you aren't very careful)

A workaround for the bug is also provided at the end of the article.
