hi guys , In my case I working on one music portal..
I have one problem guys. In my system , after some ratings by users on uploader (artist) page . I want to display one hide button which is already there.
Ex- users are rate the particular song of artist then after I admin have satified after 3 rate out of 5 then one {send for license} button to display on artist page which is already hide.

 #btn1
            {
                display:none;
            }

this button is in one division which is separate,

 <div> 
                <form action="send_l.jsp">
                    <input  id="btn1" type="submit" value="send for license"/>
                </form>
            </div>

and I has been find ratings through ajax call to one jsp. and this counter display on artist_page jsp.]

 var a = 0;
            setInterval(function ajaxcall()
      
            {

                /*< audio controls >
                     < source src = "bell-ringing-05.mp3" type = "audio/mpeg" >
                     < /audio>*/
                var xmlhttp;
                if (window.XMLHttpRequest) {
                    // code for IE7+, Firefox, Chrome, Opera, Safari
                    xmlhttp = new XMLHttpRequest();
                }
                xmlhttp.onreadystatechange = function() {
                    if (xmlhttp.readyState == 4) {
                        var res = xmlhttp.responseText;
                        //                        alert(res);
                        if (res != a) {
                            document.getElementById('counter').innerHTML = res;
                            a = res
                            abc();
                            xyz();
                        }
                    }
                }
                xmlhttp.open("GET", "l_counter.jsp", true);
                xmlhttp.send();

            }, 6000);
