Problem mit layern!

[Torben]

Nur wie muss ich das nun verbinden:

function toggle2( targetId )
{
  if (document.getElementsByClassName)
  {
    var target  = document.getElementsByClassName( targetId );

if (target.style.display == "")
    {
      target.style.display = "none"
    }
    else
    {
      target.style.display = ""
    }
  }
}

function getElementsByClassName(class_name)
{
  var all_obj,ret_obj=new Array(),j=0,teststr;
  if(document.all)all_obj=document.all;
  else if(document.getElementsByTagName && !document.all)all_obj=document.getElementsByTagName("*");
  for(i=0;i<all_obj.length;i++)
  {
    if(all_obj[i].className.indexOf(class_name)!=-1)
    {
      teststr=","+all_obj[i].className.split(" ").join(",")+",";
      if(teststr.indexOf(","+class_name+",")!=-1)
      {
        ret_obj[j]=all_obj[i];
        j++;
      }
    }
  }
  return ret_obj;
}
