[thelist] JavaScript chunk: Internet Explorer 5.5 versus Opera 6, Netscape Navigator 4.77

[Syed Zeeshan Haider]

Hi Duncan O'Neill,
Thank you for taking time to reply me. I was away for some time,
therefore, I am replying late.
Let me confess that I have never tried to write a cross-browser
compatible script. This time I felt a need to do this but too complex
script is a great obstacle for me. I just copied a part of script in my
post. Other script on the page (from which I copied JS) is very complex
(perhaps only for me because I am not very experienced and I wrote it
after a very hard work). I mostly write IE compatible JS. The web pages
are on my local machine, because I want them to be more dynamic and
bug-free before being online.
I do not clearly know how NN 4.x deal JS. Therefore, I need some further
explanation for following line:
document.layers['rut'].document.layers[imgName].src='whatever';
"layers" is confusing. Why am I supposed to use layers for NN 4.x?
Thank you,
Syed Zeeshan Haider.

Syed,

There are two things I can see which are likely to
be causing problems with N4.x, and a third which
is a possible hiccup;

1) You have to access the <divs> and their contents
differently. You may have to do something hideous like;

document.layers['rut'].document.layers[imgName].src='whatever';

2)Netscape 4.x uses 'show' and 'hide' instead of 'visible'
and 'hidden' on  <divs>. So you need to do;

if (document.layers){visible='show';
                     hidden='hide';}
else {visible='visible';
      hidden='hidden'; }

at the top of yr script, and then you can set the visibility
properties with variables instead of strings.

3) Netscape 4.x sometimes has difficulties if the styles on the
<div>s are  declared inline.

sorry I have no ideas about Opera 6, as you give no URL.

hth,

Duncan O'Neill
