How do I change an embedded video within a div?

[ryanart]

I'm currently trying to create a gallery section for my website. I have thumbnails located in the body of the website that are setup as buttons linked to embedded videos. At the top of my page I have a div that contains an embedded video. What I would like to do is click on the thumbnails and have the embedded video change in the div with a new video - without reloading the page. Is this possible?

JavaScript is a wonderful thing

<script type="text/javascript">
    function optionCheck(){
        var option = document.getElementById("options").value;
        if(option == "show"){
            document.getElementById("hiddenDiv").style.visibility ="visible";
        }
        if(option == "goto"){
            window.location = "http://google.com";
        }
    }
</script>
