Netscape frustrations ... :(

TeaAddictedGeek · Mar 2, 2000

I'm trying to create a bit of code that will rotate some graphics and text underneath to go with it. It works BEAUTIFULLY in IE, I couldn't be prouder. In Netscape, the image rotation works, and the text just sits there and thumbs its nose at me. 
 
Worse yet, the Netscape browser appears to be having an identity crisis, and detecting the browser through the standard code isn't working, either. 
 
Please help! My code is included below. It's a combination of Javascript and DHTML, hence why I'm here, pleading and moaning for someone to help before I destroy all copies of Netscape in the known universe.... 
 
 
function rotate() { 
 
browsername=navigator.appName; 
document.picform.slideshow.src = imgs[n]; 
 
 
if (browsername=="Netscape&quot

document.layers["footer"].document.write(footers[n]); 
 
else 
footer.innerHTML = footers[n]; 
 
 
(n == (imgs.length - 1)) ? n = 0 : n++; 
window.setTimeout("rotate()", timedelay); 
} 
window.onload = rotate; 
// End --> 
</script> 
 
 
<center> 
<form name=picform> 
<img name=slideshow src="../images/flower.gif"> 
 
<script> 
browsername=navigator.appName; 
if (browsername=="Netscape&quot

document.write('<layer id="footer">'); 
else 
document.write(''); 
 
</script> 
A flower! 
<script> 
browsername=navigator.appName; 
if (browsername=="Netscape&quot

document.write('</layer>'); 
else 
document.write(''); 
 
</script> 
</form>

It may be that you didn't close off your code. Compare 
 
Your code: 
 
if (browsername=="Netscape&quot

document.layers["footer"].document.write(footers[n]); 
 
 
The way it should be: 
 
if (browsername=="Netscape&quot

{ 
document.layers["footer"].document.write(footers[n]); 
}

Still not working. See code below, it returns the same error: 
 
 
function rotate() { 
browsername=navigator.appName; 
 
 
document.picform.slideshow.src = imgs[n]; 
 
if (navigator.appName.indexOf("Internet Explorer&quot

!= -1 ) 
{ 
footer.innerHTML = footers[n]; 
} 
else 
{ 
var myText = footers[n]; 
document.layers["footer"].document.open(); 
document.layers["footer"].document.write(myText); 
document.layers["footer"].document.close(); 
} 
 
(n == (imgs.length - 1)) ? n = 0 : n++; 
window.setTimeout("rotate()", timedelay); 
} 
window.onload = rotate; 
// End --> 
</script> 
</HEAD> 
 
<BODY> 
 
<center> 
<form name=picform> 
<img name=slideshow src="../images/flower.gif"> 
 
</form> 
<div id="footer">A flower!</div> 
</center>

Try using the toLowerCase() function, this seems to relieve a lot of problems for some reason, so instead of having browsername=navigator.appName, it would be browsername=navigator.appName.toLowerCase(). I don't know why this is, but it seems to work. I also just noticed that you do not put quotation marks around the you names. Netscape doesn't usually like this. I also just noticed that you reference your layer as layer["footer"], but all you really need is just footer (so instead of looking like document.layer["footer"], it would be document.footer. Get rid of the second document in document.layers["footer"].document.open(). That would confuse any browser. A layer really isn't a separate document.

Quotation around the *what* names? Please explain. 
 
And the code for the layer would be document.footer.open() then?

In answer to your question about the layer, yes that's correct. 
 
Your code: 
<img name=slideshow src="../images/flower.gif">

LAYER is a browser-specific tag, an ugly invention that tries to make up for a sub-par browser when it comes to dHTML (sorry, Netscape). Netscape tried to guess as to what direction the W3C would turn considering layers and dHTML, and they guessed wrong. IE has a far better JavaScript DOM, and the fact that the two browsers have differing DOM's is the reason you need browser-specific code. The whole thing will be a mess until Netscape 5 comes and Netscape 4 is phased out (beta release is coming in under a month!). 
 
you don't need the brackets as ndogg proposed... if you only have one statement, you don't need the brackets, so that's definitely not your problem. 
 
I don't believe in the idea of creating browser-reactive HTML code... but that's just a personal thing. One quick idea, in your "window.onload = rotate;" statement. Is "rotate" a variable or a function here? If it's a function call, you forgot your parentheses. Also... just curious. Where is the object "footer" and the array "footers" coming from? I suppose the object is a reference to the paragraph id? Also... your image is outside of your "footer" layer/paragraph... I thought you wanted it inside? 
 
Best of luck

D@^^n!t, everyone's got a gripe about Netscape, don't they? Just wait, in 25 days,beta-v6 based on Mozilla will be out and will be fully compliant with W3C's specification for HTML, CSS, XML, DOM, and JavaScript. Ooooh...I can't wait.
