<script type="text/javascript">
$(document).ready(function(){
var brow=$.browser;
var bInfo="";
if(brow.msie) {bInfo="Microsoft Internet Explorer "+brow.version;}
if(brow.mozilla) {bInfo="Mozilla Firefox "+brow.version;}
if(brow.safari) {bInfo="Apple Safari "+brow.version;}
if(brow.opera) {bInfo="Opera "+brow.version;}
alert(bInfo);
$("#browser").html(bInfo);
})
</script>
