only way to disable a div, as far as i know, is by overlaying another div on top of it with higher z-index

<div id="divToBeOverlayed"></div>

<div id="divThatOverlays"></div>

#divToBeOverlayed
{
  position:absolute;
  top:100px;
  left:100px;
  height:100px;
  width:100px;
  z-index:1;
}

#divThatOverlays
{
  position:absolute;
  top:100px;
  left:100px;
  height:100px;
  width:100px;
  z-index:3;
}

since the z-index of the divThatOverlays is higher, it will come on top and divToBeOverlayed will look like disabled

Yes, it can be used for any element as long as you have positioned that element.

you need to give position:relative for that td

i guess, even if the div with z-index 2 is not hidden, div with z-index 3 will always be enabled regardless, since it will be on top of div with index 2.
Higher index takes more priority and it overlays whatever is beneath with lower z-index

{
   var divId1ZIndex = document.getElementById(divId1).style.zIndex;
 
   document.getElementById(divId1).style.zIndex = document.getElementById(divId2).style.zIndex;

   document.getElementById(divId2).style.zIndex = divId1ZIndex ;
