[jQuery] simple browser check (need help)

[jQuery] simple browser check (need help)


I have a tool that only operates under IE
So all other browser users get an alert here is my code...but it
doesn't work...
Can someone get me straightened out?
<script>
$(document).ready(function()
    {
    if($.browser.[safari, opera, mozilla])
        {
            $( function() { alert("You must use Internet Explorer to view the
links at this time!");
        }
    );
    }
);
</script>
