57382 - citroen-web.com - [LAYER] I get a blank screen

Status: VERIFIED FIXED

(Tech Evangelism Graveyard :: English US, defect, P3)

Description

[Igor Furlan]

If you click on this URL
http://www.citroen-web.com/
you will get blank screen

This page works with NEtscape 4.73 for Linux and MSIE5.0 for windows

I  found the following text in the source of the page.
<meta name="GENERATOR" content="Microsoft FrontPage 4.0">

Perhaps THIS explains everything

Sincerely

Igor

All the text an graphics in this site are contained inside <p> tags with the
visibility set to 'hidden' initially.
If I understand things correctly, netscape 4 will show content that has a
visibilty of 'hidden', as it expectes a value of 'hide'.
When the site loads a function is called which shows the content.
This function looks for IE and Netscape and sets the visibilty to 'visible' if
the browser is IE, otherwise it leaves the visibility as is.
Therefore for Mozilla, which understands a visbilty of 'hidden', the content
will never become visbile.

When NN4.7 loads this Web page, you see no errors in the JavaScript console. 
However in Mozilla, you see this in the JavaSript console: 


                 Error:       doc_els has no properties
                 Source file: http://www.citroen-web.com/animate.js
                 Line:        105



As Conor was saying, the HTML detects IE4 correctly, and it will detect
NN4.7 correctly, but it doesn't detect Mozilla and therefore exits early
out of the key animation function. Here is a sample of the code: 


function dynAnimation(obj)
{
   animateElements = new Array()
   var ms = navigator.appVersion.indexOf("MSIE")
   ie4 = (ms>0) && (parseInt(navigator.appVersion.substring(ms+5, ms+6)) >= 4)

   if(!ie4)
   {
      if((navigator.appName == "Netscape") &&
                   (parseInt(navigator.appVersion.substring(0, 1)) >= 4))

              doc_els=document.layers
      else
              return
   }
   else
      doc_els=document.all


                    etc. 
                    etc. 



We can see from this that doc_els will never gets defined in N6/Mozilla.
NN4.7 supported document.layers, but N6/Mozilla doesn't, as per the W3C spec.
