<!-- Javascript goes in the document HEAD -->
<script type="text/javascript">
function altRows(id){
        if(document.getElementsByTagName){  
                
                var table = document.getElementById(id);  
                var rows = table.getElementsByTagName("tr"); 
                 
                for(i = 0; i < rows.length; i++){          
                        if(i % 2 == 0){
                                rows[i].className = "evenrowcolor";
                        }else{
                                rows[i].className = "oddrowcolor";
                        }

window.onload=function(){
        altRows('alternatecolor');
}
