show is not a valid value of display It should be block or inline-block — Rory McCrossan

Try the following:

var shad ='SUBJECT';      
if (shad !="") {
  document.getElementById("subjectr").style.display = 'none';
}
else {
  document.getElementById("subjectr").style.display = 'block';
}

sub: <input type="text" name="subjectr" id="subjectr" value='SUBJECT'/>
