I would like to scroll The div bottom to the bottom of the page when page loads but will also like to scroll back up when needed to how can i archive this without any animations how can i achieve this
echo "<div id='bottom'><p><b>$from_username</b><br />$message</p></div>"; 
<script>
    function scrollpage() {     
        function f() 
        {
            window.scrollTo(0,i);
            if(status==0) {
                i=i+40;
                if(i>=Height){  status=1; } 
            } 
        setTimeout( f, 0.01 );
        }f();
    }
    var Height=document.documentElement.scrollHeight;
    var i=1,j=Height,status=0;
    scrollpage();
    </script>
this is what i have so far, i am able to scroll down automatically but can not scroll up when i want to, what can i do if i want to scroll up ?
