If you browse these forums using Opera 8.x, you will notice the link fader doesn't work too well. I believe this is due to Opera fixing their DOM to be more standard in the new release. Just replace the detection logic:

Before:
Code: [ Select ]
if (navigator.userAgent.indexOf("Opera") != -1) opera = true
else if (document.all && !opera) ie = true
else if (!document.all && document.getElementById) dom = true;
  1. if (navigator.userAgent.indexOf("Opera") != -1) opera = true
  2. else if (document.all && !opera) ie = true
  3. else if (!document.all && document.getElementById) dom = true;

After:
Code: [ Select ]
// Modified to let Opera 8 use standard dom
opera = false;
ie = false;
dom = false;

if (navigator.userAgent.indexOf("Opera 8") != -1 || navigator.userAgent.indexOf("Opera/8") != -1) dom = true;
else if (navigator.userAgent.indexOf("Opera") != -1) opera = true;
else if (document.all && !opera) ie = true;
else if (!document.all && document.getElementById) dom = true;
  1. // Modified to let Opera 8 use standard dom
  2. opera = false;
  3. ie = false;
  4. dom = false;
  6. if (navigator.userAgent.indexOf("Opera 8") != -1 || navigator.userAgent.indexOf("Opera/8") != -1) dom = true;
  7. else if (navigator.userAgent.indexOf("Opera") != -1) opera = true;
  8. else if (document.all && !opera) ie = true;
  9. else if (!document.all && document.getElementById) dom = true;

Opera 8.0 seemed to need the variables to be explicitly set (true of false) rather than undefined.

I don't know if the fix applies to the 7.x series of Opera. If so, it could be extended to check for Opera 7.

I think someone needs to take a look at the fader.js script here on Ozzu.

It throws errors almost constantly in Firefox, and rarely, it throws about 10 errors a second, which clogs up the Firefox JS console so bad, it slows the browser to a crawl until I refresh the page or click a link.

The first error is:
Code: [ Select ]
Error: fader is not defined
Source File: http://www.ozzu.com/fader.js
Line: 130
  1. Error: fader is not defined
  2. Source File: http://www.ozzu.com/fader.js
  3. Line: 130


the second error is:
Code: [ Select ]
Error: document.links[x] has no properties
Source File: http://www.ozzu.com/fader.js
Line: 118
  1. Error: document.links[x] has no properties
  2. Source File: http://www.ozzu.com/fader.js
  3. Line: 118


and the one that clogs my JS console is:
Code: [ Select ]
Error: uncaught exception: [Exception... "Object cannot be created in this context" code: "9" nsresult: "0x80530009 (NS_ERROR_DOM_NOT_SUPPORTED_ERR)" location: "http://www.ozzu.com/fader.js Line: 58"]


All of this is on Firefox 1.0.6 (but has happened since at least 1.0.4)

Anyone else seeing similar behavior or is it just me?

I use FireFox both on linux and windows and it works fine, not sure what could it be.

Check your Javascript Console. Sometimes when it seems that Ozzu is lagging, it's actually doing the 10-second thing I mentioned above.

Should have mentioned this when I posted, this is on Windows. Under Suse 9.3 I have no problems.

Interesting. I get the lagging from time to time but never associated it with the fader.js. But you are correct. The error is there. My javascript console is loaded with them.

I've seen this error since waaaaay back - ever since I started using Firefox (about 0.9-ish). Never reported the error as I never thought it was a big deal.

So if I am understanding correctly this error seems to happens randomly? If any of you can figure out when it happens exactly that would help me duplicate the problem so that I can attempt to fix it.

The primary error is this:
Error: hex has no properties
Source File: http://www.ozzu.com/fader.js
Line: 77

The code function is:
Code: [ Select ]
function convert2Dec(hex)
    {    
        var rgb = new Array();
        for (var u = 0; u < 3; u++)
            rgb[u] = parseInt(hex.substring(u*2, u*2+2), 16);
        return rgb;
    }
  1. function convert2Dec(hex)
  2.     {    
  3.         var rgb = new Array();
  4.         for (var u = 0; u < 3; u++)
  5.             rgb[u] = parseInt(hex.substring(u*2, u*2+2), 16);
  6.         return rgb;
  7.     }


Other errors:
Error: fader is not defined
Source File: http://www.ozzu.com/fader.js
Line: 130

Code: [ Select ]
function clearFade()
    {
        if (document.layers) return;
        if (fader) clearInterval(fader);
        fader = setInterval("fade(" + x + ", 0)", speed);
    }
  1. function clearFade()
  2.     {
  3.         if (document.layers) return;
  4.         if (fader) clearInterval(fader);
  5.         fader = setInterval("fade(" + x + ", 0)", speed);
  6.     }


Error: document.links[x] has no properties
Source File: http://www.ozzu.com/fader.js
Line: 118

Code: [ Select ]
function findLink(over)
    {
        if (document.layers) return;
        if (fader)
            {
                clearInterval(fader);
                document.links[x].style.color = "#" + ocs[x];
            }
        if (over && !this.id) this.id = over;
        x = 0;
        while (!(this.id == document.links[x].id) && (x < document.links.length))
            x++;
        if (this.id == document.links[x].id)
            {
                oc = currentColour(x);
                fader = setInterval("fade(" + x + ", 1)", speed);
            }
    }
  1. function findLink(over)
  2.     {
  3.         if (document.layers) return;
  4.         if (fader)
  5.             {
  6.                 clearInterval(fader);
  7.                 document.links[x].style.color = "#" + ocs[x];
  8.             }
  9.         if (over && !this.id) this.id = over;
  10.         x = 0;
  11.         while (!(this.id == document.links[x].id) && (x < document.links.length))
  12.             x++;
  13.         if (this.id == document.links[x].id)
  14.             {
  15.                 oc = currentColour(x);
  16.                 fader = setInterval("fade(" + x + ", 1)", speed);
  17.             }
  18.     }


Unfortunately Firefox's javascript console doesn't give the time of the error, so I've cleared my log in an attempt to discover when it happens.

It appears to be random. Same three errors. I was able to initiate the error by mousing over the Meet The Mods Link and I got the error when entering this post to reply. But I wasn't able to consistantly duplicate the errors.

I think the error comes about when you "mouse over" a link before the page loads up entirely. If you refresh the page, or click on one of the forums, and then quickly mouse over some links, you'll see the error in the JS console.

Yes. I can duplicate the errors fairly consistantly that way.

I see the lag error after replying mostly, I think.

I did get that frequently as well. I seem to be able to duplicate it more consistantly where simple_header.tpl is involved.

//edit -- strike that. I forgot the reply thing uses overall_header.tpl
