I am setting up a bio section on my site and I have 3 images of employees and 3 divs with each of the employees bios below. I want to hide all the bios by default and then display only the div associated with the image that is clicked and hide all other divs.

Currently it seems like it's not finding the elements because I am getting undefined

Here is my HTML so far:

<div onclick=showhide('bill'); class=bio_image><div class=name>Bill Murray</div></div>

<div onclick=showhide('bill2'); class=bio_image><div class=name>Bill Murray</div></div>

<div onclick=showhide('bill3'); class=bio_image><div class=name>Bill Murray</div></div>

<div class=hide id=bill>BILL</div>

<div class=hide id=bill2>BILL2</div>

<div class=hide id=bill3>BILL3</div>

And my Javascript:

function showhide(id){

        if (document.getElementById) {

          var divid = document.getElementById(id);

          var divs = document.getElementsByClassName(hide);

          for(var div in divs) {

             div.style.display = none;

          }

          divid.style.display = block;

        } 

        return false;

 }

JSFiddle

Any ideas? Thanks!
