Wait until the DOM is loaded?

<script src="http://static.opentok.com/v2/js/opentok.min.js" type="text/javascript"></script>
<script type="text/javascript">
document.addEventListener("DOMContentLoaded", function(event) { 
    var apiKey = xxxxxx;//my apikey
    var sessionId ="<%=@group.sessionId%>" ;
    var token = "<%=@opentok_token%>";
    var session;
    OT.setLogLevel(OT.DEBUG);

    session = OT.initSession(apiKey,sessionId);

    session.on
    ({
        streamCreated: function(event)
        {
            session.subscribe(event.stream,'subscribersDiv',{insertMode: 'append'});
        }
    });

    session.connect(token,function(error){
        if(error)
        {
            console.log(error.message);
        }
        else{
            session.publish('myPublisherDiv',{width: 320,height: 240});
        }
    }); 
});
</script>

another method

add

<div id="myPublisherDiv"></div>
<div id="subscribersDiv"></div>
