APEX

Hi All

I am using apex 5.0.3

Trying to disable the popup lov text field and button based on condition from other column.

Here is my code

<script language="JavaScript" type="text/javascript">
function disableItems(checkcolumn, columnvalue, disablecolumn)
{
 var f1 = document.getElementsByName(checkcolumn);
 var f2 = document.getElementsByName(disablecolumn);
 var k;
  if (f1)
 {
  for (k = 0; k < f1.length; k++)
   {  
   if (f1[k].value !== "")
    {  
    f2[k].disabled = true;
    f2[k].style.backgroundColor = 'silver'; 
    }
  }
 } 
}


function enableItems(column)
{
 var x = document.getElementsByName(column);
 var k;
 if (x)
 {
  for (k = 0; k < x.length; k++)
  {
    x[k].disabled= false;
   x[k].style.backgroundColor = 'white';
  }
 }
}
</script>

I am using dynamic action to fire this code on page load disableItems('f12', 'Y', 'f04')

I am able to make text area disable but the lov button still show up and when user makes changes via clicking button then lov values it accept the values.

How can I disable/not show the LOV button.

Thanks in advance for your time.
