Hide Other Divs with Hide/Show

Question

I'm using the below javascript code to hide and show some divs. When I click on an icon, it expands a div. When I click on another icon, it expands another div but doesn't close the original div. I want it so that there can only be one div open at a time and that the opened divs close when you click on another icon.

<script type="text/javascript">
    function unhide(divID) {
      var item = document.getElementById(divID);
      if (item) {
        item.className=(item.className=='hidden')?'unhidden':'hidden';
      }
    }
 </script>

 <script type="text/Javascript">
   function hideshow(id) {
     if (document.getElementById(id).style.display == ""){    
       document.getElementById(id).style.display = "none";
      } else {
        document.getElementById(id).style.display="";
      }                 
    }
 </script><!--javascript to hide and unhide a div-->

Below is some of my HTML:

Answer 1

I ended up figuring it out. I changed my javascript to the below and kept my HTML the same.

<script type="text/javascript">
function hideshow(d)
{
var onediv = document.getElementById(d);
var divs=['foryou','forteam','forcustomers','forcommunity'];
for (var i=0;i<divs.length;i++)
  {
  if (onediv != document.getElementById(divs[i]))
    {
    document.getElementById(divs[i]).style.display='none';
    }
  }
onediv.style.display = 'block';
} 
</script>
