Javascript Object Visibility

Hey all,

I am trying to do some error checking in my javascript code and I have ran across an issue with the visibility of an object.

I am hiding an object on the page using document.getElementById('objectname').style.display = 'none';

When I go to see if it exists using the code below (the object IS not visible on the screen at the time), nothing happens

if(document.getElementById('objectname').style.visibility == 'hidden')
{
alert('message');
}


I have also used with no avail:


if(document.getElementById('objectname').style.display == 'none')
{
alert('message');
}

Any ideas?
