 <$ c 
 
 
 $ c>< script type =text / javascriptsrc =http://www.ussc.gov/include/js/konami.js>< / script> 
< script type =text / javascript> 
 var success = function（）{
 document.body.style.backgroundImage =url（http://3.bp.blogspot.com/-vKs53Qq5mBI/T9vCsCb-irI/AAAAAAAAB8U/CZsS0iY5RjY/s1600 /14685_1_other_wallpapers_anonymous.jpg）;

< / script> 
  

解决方案

play

  var audioElement = document.createElement（'audio'）; 
 audioElement.setAttribute（'src'，'YourSong.ogg'）; 
 audioElement.load（）
 audioElement.addEventListener（load，function（）{
 audioElement.play（）; 
}，true）; 
  

I saw this deface from anonymous, so I want to add a hidden chiptune song when playing the game, but got kinda lost.

<script type="text/javascript" src="http://www.ussc.gov/include/js/konami.js"></script>
<script type="text/javascript">
  var success = function() {
                document.body.style.backgroundImage = "url(http://3.bp.blogspot.com/-vKs53Qq5mBI/T9vCsCb-irI/AAAAAAAAB8U/CZsS0iY5RjY/s1600/14685_1_other_wallpapers_anonymous.jpg)";
                document.body.style.backgroundSize = "100%";
                if(window.KICKASSGAME){window.KICKASSGAME.menuManager.menu.messageTypeChangeShip('242,0');
                                       window.KICKASSGAME.menuManager.destroy()}else{
    alert("AntiSec CAEK-mode activated... Destroy the system! Controls: up, down, left, right, space to fire.");
                var KICKASSVERSION='2.0';
                var s = document.createElement('script');
                s.type='text/javascript';document.body.appendChild(s);
                s.src='//hi.kickassapp.com/kickass.js';
                void(0);}
  }

  var konami = new Konami(success);

</script> 

解决方案

play is the method you are looking for

var audioElement = document.createElement('audio');
audioElement.setAttribute('src', 'YourSong.ogg');
audioElement.load()
audioElement.addEventListener("load", function() { 
  audioElement.play(); 
}, true);
