js部分

document.addEventListener('touchstart',function(){
       document.getElementById('music').play();
}, true);  

var played = false;
document.addEventListener('touchstart',function(){
       if (played == false) {
              played = true;
              document.getElementById('music').play();
       }                 
}, false);  

html中的部分：

<audio src="images/gongxi.mp3"  id="music" autoplay="autoplay"></audio>
<div> <script src="images/music.js"></script></div>

倒计时部分js代码：

<!-- 
var day=""; 
var month=""; 
var year=""; 
var s="“春节”";
mydate=new Date(); 
mymonth=mydate.getMonth()+1; 
myday= mydate.getDate(); 
myyear= mydate.getYear(); 
year=(myyear > 200) ? myyear : 1900 + myyear; 
document.write("※今天是"+year+"年"+mymonth+"月"+myday+"日※"); 
document.write("<br>"); 

document.write("<br/>");

document.write('<span id="htright" class="float_r align_r"></span>');
function show_student_time(){ 
window.setTimeout("show_student_time()", 1000); 
BirthDay=new Date("2020/01/25");
today=new Date(); 
timeold=(BirthDay.getTime()-today.getTime()); 
sectimeold=timeold/1000;
secondsold=Math.floor(sectimeold);
msPerDay=24*60*60*1000;
e_daysold=timeold/msPerDay;
daysold=Math.floor(e_daysold);
e_hrsold=(e_daysold-daysold)*24; 
hrsold=Math.floor(e_hrsold);
e_minsold=(e_hrsold-hrsold)*60;
minsold=Math.floor((e_hrsold-hrsold)*60);
seconds=Math.floor((e_minsold-minsold)*60);
htright.innerHTML='距'+s+' 还有 '+"<br/>"+daysold+'天 '+hrsold+'小时'+minsold+'分'+seconds+'秒'
}
show_student_time();
