Changing Style Class in Netscape

[Memnoch1207]

I created a custom textbox control in .NET, which calls a javascript function whent he control gets the focus. The function get's the contorls css className then adds the word "_Selected" on the end
So a control whose cssClass (className) is "textBox", would then have it's className changed to "textBox_Selected".

Everything works fine in Internet Explorer, but not in Netscape. So I was curious if anyone new why?

Here is the javascript function

function activeField(ptr)
{
   'Get the current cssStyle
   var myClass = ptr.className;

   if((ptr.disabled != true) && (ptr.readOnly != true))
   {
      'Append '_Selected' to the current cssStyle
      ptr.className = myClass + '_Selected';
   }
} 

When the control get's the focus, the color just changes to white, however, it should change to a light brown.

The function looks fine to me, except for how you're written your comments. I'm suprised it even workied in IE.
You probably added those comments just now though.

The only other thing I can think of is that NS doesn't support this yet or that or displayes the colour differently to IE, try something like black, see what happens then.
