How to hide/show div based on variable using javascript

I am trying to display a div based on the URL parameter. I have to use only html css and javascript. I got it working until the part where the div must be set to display none if the variable (parameter from URL) matches.

HTML

   <div id="cfiblinks">
     <div class="row">
       <div class="twelve columns">
         <ul class="nav-bar">
           <li>
             <a href="#" target="_blank">
               <span>Order Document Upload</span>
             </a>
           </li>
           <li>
             <a href="#" target="_blank">
               <span>Business Card History</span>
             </a>
           </li>
           <li>
             <a href="#" target="_blank">   
               <span>Material Inventory</span>
             </a>
           </li>
         </ul>
        </div>
     </div>
   </div>

Javascript

<script language="JavaScript">

    function getURLParameter(name) {
        return decodeURIComponent((new RegExp('[?|&]' + name + '=' + '([^&;]+?)(&|#|;|$)').exec(location.search)||[""])[1].replace(/\+/g, '%20'))||null
    }

    myvar = getURLParameter('UserGroupId');

    document.write('The url parameter is: ' + myvar +'       ');

    if (myvar == 10102) {
        document.write('The url parameter is: ' + myvar +'     ');
        document.getElementById('cfiblinks').style.visibility = 'visible';
    } else {
        document.write('The url parameter is not : ' + myvar +'      ');
        document.getElementById('cfiblinks').style.visibility = 'hidden';
    }


</script>

Any help would be greatly appreciated. I suspect something is wrong with the document.getElementById.

Try this..

if (myvar == 10102) {

    document.write('The url parameter is: ' + myvar +'     ');
    document.getElementById('cfiblinks').setAttribute("style", "display:block");

} else {
   document.write('The url parameter is not : ' + myvar +'      ');
   document.getElementById('cfiblinks').setAttribute("style", "display:none");
  }

Try:

document.getElementById('something').style.display = "block";


and

document.getElementById('something').style.display = "none";

You can set the display property using block or none.

document.getElementById('cfiblinks').style.display = 'block'; //Will show
document.getElementById('cfiblinks').style.display = 'none'; //Will hide
