174156 - barnettpage.com - Buttons on web page don't work, LAYERS

Status: RESOLVED INVALID

(Tech Evangelism Graveyard :: English US, defect)

Description

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC; en-US; rv:1.2b) Gecko/20021011

On this page, is a picture of a remote control.  There are some blue buttons
that, when clicked on, alter the contents of the LCD display on the top as well
as the text on the right.  But this only works in Internet Explorer, not in
Mozilla.  In Mozilla, clicking on the buttons does nothing.

I don't know if this is an evangelism issue or not, because this could either be
because Mozilla doesn't support some obscure HTML command, or because the web
page is providing different HTML for IE vs. Netscape, or whether it's
genererating bad HTML.

Reproducible: Always

Steps to Reproduce:
1. Visit page
2. Click on blue buttons along left and buttom of LCD display
3. There is no step 3! (Apologies to Jeff Goldblum)

Actual Results:  
Nothing

Expected Results:  
The contents of the LCD display and the text to the right should change.

I forgot to mention that similar problems occur on the main page,
http://www.barnettpage.com, as well as the rest of the site.

The page you are talking about contains a script, which has lines like this in it:

function CSIEStyl(s) { return document.all.tags("div")[s].style; }
function CSNSStyl(s) { return CSFindElement(s,0); }
function CSFindElement(n,ly) { if (CSBVers < 4) return document[n];
	var curDoc = ly ? ly.document : document; var elem = curDoc[n];
	if (!elem) { for (var i=0;i<curDoc.layers.length;i++) {
		elem = CSFindElement(n,curDoc.layers[i]); if (elem) return elem; }}
	return elem;
}

Other functions are similar.

So, it uses only document.all and document.layers, and not the usual
document.getElementById(). Mozilla does not have document.all (as it's MSIE
specific method) nor document.layers - it has only the document.getElementById().

So, this is not a bug in Mozilla. This is a very badly designed website.

indeed.  the page assumes that if the browser isn't IE, it must be NS4

Why can't Mozilla implement document.all?
