1 ['mousedown', 'touchstart'].forEach(function(name){  
 2         window.addEventListener(name, function _mousedown () {
 3           function audioAutoPlay() {
 4               var musicEle0 = document.getElementById('audioPlay');
 5                   musicEle0.src = 'data:audio/mp3;base64,'
 6                   musicEle0.play();
 7           }
 8           audioAutoPlay();
 9           window.removeEventListener(name, _mousedown);
10         });
11       });
