zoom problem in FF, working in IE

[muisjepiep]

hey

this code works in IE but not in FF

function ZoomFrames(obj)
{
    if (isVisibleObject(document.getElementById("FRHEAD").style))
    {
        document.getElementById("FRZOOM").src='images/zoomin.gif';
        hideObject(document.getElementById("FRHEAD").style);
        hideObject(document.getElementById("FRINDEX").style)
    }
    else
    {
        document.getElementById("FRZOOM").src='images/zoomout.gif';
        showObject(document.getElementById("FRHEAD").style);
        showObject(document.getElementById("FRINDEX").style)
   }
}
 
ns4 = (document.layers)? true:false
ie4 = (document.all)? true:false
 
function showObject(obj)
{
    if (ns4) obj.visibility = "show"
    else if (ie4) obj.display="block"
}
 
function hideObject(obj)
{
    if (ns4) obj.visibility = "hide"
    else if (ie4) obj.display="none"
}

does anybody has an idea?

Firefox doesn't support either document.layers or document.all.

If you don't need to support Netscape 4, just set the display property instead for all modern-ish browsers.
