CSS-Klassen

[Struppi]

Hallo alle zusammen,
wie kann ich CSS-Klassen mit Javascript ändern?

so:

function setClass(className, attr, value)
{
    var rule = getStyleSheet(className);
    if(rule) rule.style[attr] = value;
}
function getStyleSheet(className);(name)
{
     if(!document.styleSheets) return null;
     if(!name) return null;
     for(var i = 0; i < document.styleSheets.length; i++)
     {
         var rules = document.styleSheets[i].rules;
         for(var j = 0; rules && j < rules.length; j++)
         {
             if(rules[j].selectorText == name) return rules[j];
         }
     }
     return null;
}

Struppi.
